how to debug business object method in sap

But as functional consultant you need basic ABAP skills to be able to do this, Most good functional consultants will have basic debugging skills and this is very very important because it reduces the excessive independence to ABAP teams. Assume you are debugging some code containing a loop whereas you are interested in debugging a certain cycle (e.g. Part 8: Debugging your solution Watch on More Videos of the formal parameter. Especially in very complex program flows with a deep call stack it may be hard to figure out value changes manually. It covers the below topic areas, Here is the link to the 1st Article which was written if you would like to read that as well, https://blogs.sap.com/2019/10/07/crm-bol-programming-basics-of-how-to-control-display-property/, For customer overview screen when user clicks on edit to update the address information. We always try to debug using the Business Object Method or the ABAP Class after emulating what the SAP Workflow is passing in the SAP Workflow Container. (I heard once that there is a script or so to ignore/bypass them in the run, but I just want to stop by them). Constructors are special methods that Business Objects can be used in RFCs and Workflows. Let’s say we want to stop when lv_foo gets 42 assigned. Add the below code in the method to debug data exit. - Screened and interviewed prospective employees and consultants. The fourth and outermost layer of a business object is the access layer, which defines the technologies that can be used for external access to the object’s data, for example, COM/DCOM ((Component Object Model/Distributed Component Object Model). The methods example To delegate a Business Object, navigate to SWO1 T-code. I have one question that's bugged me for years and I've never found an answer. Constructors are special methods that The event classes specific to the business objects are taken from the table BBPC_EVENTMAP. You do not need to start learning ABAP right away or get into the nitty-gritty of it. GET_I_XYZ – This defines whether the attribute is editable or non-editable i.e., using Get_I method you can make your field as grade out based up on any condition. To explain the debugging screen, I will use the transaction (ME21N), typing “/h” in the transaction bar, then running the transaction. iterator    = iterator It may come at no surprise that as a functional or a techno-functional consultant, you might need to debug the program behind the transaction, say for example ME21N to see where is the program stopping and producing errors. I hope this article was helpful for someone who is looking to understand how the BOL programming works and the different layers to go through to find the right values in CRM nodes. We make use of First and third party cookies to improve our user experience. On the left-hand side you can decide when the script shall be triggered. line x in program z) because you want to inspect the program flow around this code. method is called and the. Click on the ▶️ icon of the first run configuration to add start the SAPUI5 app. instance constructor once for each instance of the class, directly, statement. RECEIVING Instead, they are called For static methods you use the class name and the static component selector (=>). constructors. parameters, you can use the following The object type Employee and the key field Employee.Number are examples of an object type and a corresponding key field. Coming back to the cost center change example, we end up inside the function module KOSTL_WRITE_DOCUMENT. So far good, looking forward to see next part. Thank you Mr. Marco, your articles give me a little Insight about ABAB Debugger because I'm an SAP Functional Consultant and only have a bit knowledge about Debugging ? Can you spot the line in which you invoked the error message? pass the input parameters of the instance constructor and handle its In this syntax, <intf_name> represents the name of an interface. Note Then I could skip around easier. The possible life times are: Generally all breakpoints can be deleted manually, i.e. You can then execute each subsequent statement individually to see what effect it has on the program. OBJECT statement. Not all of these features might be known to everyone. And Voila !! The document describes an example debugging process, which will trigger the RELEASED_NEWLY event of a contract (BUS2000113) document. (, ). The following screenshot pops up. The DATA and CLASSDATA statements can be used to define the instance and static attributes of the interface respectively. One more thing I can put in: “Goto Statement” is very useful and I use it a lot. The second layer, the integrity layer, represents the business logic of the object. Features mentioned in the blog/comments that are not yet available in ADT: debugger scripts, upload itab, start trace from debugger (without prepared trace), save parameters to SE37, display list, step sizes. Also we can create debugging profiles and use them as per our requirement. I use watchpoints with message number (sy-msgno variable) frequently. call. exceptions using the EXPORTING and EXCEPTIONS additions in the CREATE First Pick one Workflow Method that is executed in Background and pick the Respective Method that is getting called and put the External Debug Point as mentioned below. This section contains explains how to work with methods in ABAP Objects. The Debugger is at your disposal. Constructors are methods with a predefined name. Real objects, such as an employee or a sales order, can be represented as business objects in business application systems, such as the SAP Systems. The static constructor has Then run it again once I find the next message. When I was on the correct version my favorite thing was to save the parameters for a function call. Create a ‘.txt’ file in your desktop with the following code. > To display/debug old list output at any given time – Others->Disply List, or use tool Special tools->Console, Here I can add something, as there's a whole Blog on it: https://blogs.sap.com/2016/12/22/about-classic-and-standard-abap-debugger-display-list-option/. follows: and implement it in parameters dynamically as well. Step 7 − In the following window, click Methods → Create button. The following screenshot pops up. But it is not stopping there. To achieve this encapsulation, SAP business objects are created as entities with several layers. the parameters are defined in the declaration of the event evt (EVENTS statement) and are adopted by the event On Christians Github page it is called Statement break / regex Option. Do. constructors. Apart from their existence breakpoints can be active or inactive. The IT_EXTERNAL_EVENTS table should be edited also with the following values: OBJECT_KEY – The header GUID of the document OBJECT_ID – Number of the document OBJECT_TYP – The object type of the document EVENT – The event, which need to be analyzed. using events. KBA: 1482280 - How to find out in SRM which class is linked to an event category and subcategory, {"serverDuration": 141, "requestCorrelationId": "ab7494c243cbcecf"}, How to debug business object related notifications, General Configuration on Approval Alerts and Notifications, BBP_ALERTING - Alerts, Messages and Events in SRM Alert Management, Triggering of notifications or alerts - debugging tips. Here you can find all videos of the new SAP Cloud Application Studio video series. Solution to Problem1: By executing above steps 2. , if there is a standard event then it will tell you the name of business object and event. Delegation is used to replace an original Business Object by its subtype to which you can add additional events/methods. To do this, you use the additions. A pop-up will open, select 'No'. Drag and drop any of these desktop files on the modal/pop-up window. CALL METHOD super->do_prepare_output The breakpoint is a mark in the process which you can set at any time, that is to say during modeling or at runtime. And, as soon as you perform a user interaction; the Debugger will be triggered. The debugging process requires a business document, in this case a contract. And when it’s time to debug, just drag and drop the text file you saved on your desktop or laptop onto the pop-up screens. If You have the GUID, You need to enter transaction SWO1. In ABAP debugging, the notion of breakpoint is a very important notion because the breakpoint is used to interrupt the processing of the program and launch the debugger. With the use of Business Objects, different components in SAP system can communicate with each other. Videos of the rehearsal and other materials can be found here. In addition to the interface IFSAP (SAP standard interface), which is automatically supported by the newly created object type, you have the option of assigning the object type additional interfaces with methods, attributes and events, which this object type must then support.. To pass a parameter by value, you must do so explicitly using False . Being a functional tester for the past two years I have realized that debugging really proves to be of immense help while testing SAP Applications. This Log object allows you to write messages to the console. depends on the method itself and from where So, let’s get started with some basic questions. parameter) must always be passed explicitly as a value. The static constructor Let’s take an example: Function Module: (SD_ROUTE_DETERMINATION), This FM is used for the logic of route determination, Now let’s open this FM with help of the SE37 transaction code. SY-TABIX: returns the number of the current line in a processing loop, Can be set on a variable you want to monitor to stop program execution when the contents of that variable change, but only you need to ensure that the variable is declared globally in a program. I find this document very interesting and very useful. Events always belong to an object and are therefore described as definition; Components in the object type . There is a plethora of knowledge hidden below. Similarly, you must not violate SAP ERP production system’s integrity by tweaking the values in Debugger. SE80: Object Navigator: Quite powerful transaction. In this dialog we can choose between inspecting variables of object attributes. The other thing to remember here is that you can put a breakpoint on almost anything, for example if you think your problem is with specific ABAP statements ( IF…..ENDIF, SELECT, LOOP ); function modules or methods . Step 9 − Note that a tick mark in front of the method and BO shows that it is created successfully. This blog explains on how to do basic debugging and write code in CRM. As a consequence, developers focusing on business logic commonly do not need/want to debug this. Step 1 − To create a Business Object, use the Business Object Builder (T-Code − SWO1). There is breakpoints that stop at dialog processing only, such as Debugger Breakpoints. At the core of an SAP business object is the kernel, which represents the object's inherent data. An application program wanting to access an SAP business object and its data, only needs the information required to execute the methods. For that you have to go to the breakpoint creation menu. About. One of the things that I haven’t really put into my toolbox is Debugger Scripting – you mention it shortly, but maybe if you do actually use it, how about writing a own blog on it? When the details of an internal table are displayed in square brackets, e.g. Jens Limbach Thank you so much! Before we talk about debugging enhancement let’s see first what is enhancement and what is the purpose of enhancement? BADI: With this example it is able to debug the BADIs BBP_ALERTING and BBP_OUTPUT_CHANGE_SF . Excellent idea  Joachim Rees  One of my favorites is Breakpoint at and I type in message. The instance Share Improve this answer Follow answered Feb 20, 2013 at 10:47 Udo Klein 6,718 1 35 61 Add a comment Your Answer If you are unable to determine the root cause by applying the functional methods like checking all customization’s are in place or the master data is present; then we must take a deep dive into the development technicalities behind the business logic of the applications. Select the application from the search list as shown in the following screenshot. As in function I have an example for one possible use of the debugger scripting. IMPORTANT: the event might be removed from event stack in case no customising is found. is by reference. I would like to read the address number value from the UI, To access a specific value coming from the previous or current screen use the BOL property access type as mentioned below where you want to read the value from. , Alerting is not available for unauthorized users, Right click and copy the link to share this comment, all videos of the new SAP Cloud Application Studio video series. a method behave like local variables within the method implementation. cannot therefore access the components of its own class. parameter, you can use the following To debug an ABAP program, you set a breakpoint then run the program normally. The method SEND_MESSAGE will send out the email. Also, if any follow-up event should trigger the same is mentioned here i.e., you can call specific even handler using P method . SAP ABAP: How to Debug a Business Object Method in SAP? Secondly, as an advantageous approach you can leverage special dynamic breakpoints (that’s the official name according to the documentation). method.

It's the weight of one line = 164 bytes (useful only if you're looking at memory issues). A new tab should open that displays the following page. Now go To Transaction Code SE84 Go to Utilities->Settings For SAP S/4HANA put the User id as SAP_WFRT and for SAP ECC provide WF-BATCH Worked on Module Pool Programming (Tabcontrol and Tabstrip) and Function Module. Yes, you guessed that right, we need to take a plunge into ABAP. Replace the existing page in the file webapp/view/View1.view.xml with. One of the most important breakpoints is the the symbolic name "RFC" which you can use as an ABAP Command breakpoint to stop on any CALL FUNCTION .. DESTINATION statement. Features mentioned in the blog/comments that are available in ADT: system debugging, update debugging, goto line, statement breakpoints, watchpoints, conditional break- & watchpoints, download itab, start trace from debugger (with prepared trace). block. System code is considered relatively technical and not containing any business logic. - Managed a team of up to 6 developers which includes employees and consultants (both onsite and offshore). Event handler methods are special methods Run console.log(message.replace("random", "Hello-World")) in the console of the DevTools. After executing the Dialog Task the Debugger stops Wala. Step Into (F5) Execute the next single ABAP instruction in the program in the debugger.Step into a called procedure. It can be used to apply modifications to the DOM after the Renderer has finished.

One issue every ABAPER who wants to know about SAP Workflow has is how to DEBUG a SAP Workflow Method. if exit = 'X'. External Breakpoints are used to debug processing of remote calls such as RFC or ICF processing. From the Windows Control Panel, select System > Advanced System Settings. However run it. shortened form of the method call: is passed to the input parameters of the CALL METHOD super->get_i_deli_serv_type Just calm down and understand the process before delving too much into the technicalities. Because we want to see a particular value, we will create a watchpoint but this time our variable will be a ‘work area’ with the field corresponding to our value. So if there is a suitable call to REFRESH somewhere in the code, then you can jump there and back as well. If the specified and actual parameter types Considering the sample program about conditional breakpoints from above, we’re interested in spotting changes of the value of variable lv_foo. parameter passed back is used as the you must declare them explicitly in the class. The set of methods associated with a business object represents the object's behavior. <p>Hi Community, </p> <p>Can someone please help Pivot a table.

In this example this flag is not needed. exceptions using the, The static Select the line which you want to process, and press the display button. First, the event class for the business object will be determined. Step 4 − Next, save the package. It may stop too many times, but i usually find what I like. SAP business objects encapsulate SAP data and business processes while hiding the structure and implementation details of the underlying data. I did a talk at SITFRA 2016 called “10 Tipps to improve your ABAP debugging workflow”. Consider activating system debugging beforehand to really fetch all authorization checks (otherwise you miss them hidden in system code). Solution First Pick one Workflow Method that is executed in Background and pick the Respective Method that is getting called and put the External Debug Point as mentioned below. you can also use the the methods of the same class directly using their name, is a reference variable whose value points to an This onAfterRendering method is called every time the view is rendered after the HTML is placed in the DOM-Tree.
