24INTERFACE0709 – Steps to create Own Custom BAPI
- Create a Function Module
– Go to SE37 (Function Builder) and create a new function module.
– Ensure the function module is remote-enabled. In the properties tab, mark the function module as RFC (Remote Function Call) capable.
– Define input, output and changing parameters as required.
- Define Import/Export Parameters
– In the Import/Export tab, specify the parameters for your function module.
– Typically, the Import parameters are data passed to SAP and Export parameters are the results sent back to the caller.
– Map the parameters according to your business logic needs.
- Write the Business Logic
– In the Source Code tab, write the necessary ABAP code to fulfill the business requirement.
– Ensure you handle exceptions properly by defining Exception Handling
- Generate Function Group
– Every function module belongs to a Function Group. If you don’t have a group, create one using transaction SE80.
– After creating the function group, activate it along with the function module.
- Create a Business Object
-Go to SWO1 (Business Object Builder).
-Enter a name for your custom business object and create it.
-Assign a suitable program object type and name the key fields.
-Under the Methods tab, choose the option to create a new method.
- Link the Function Module to the Business Object
– Assign the previously created function module to the method of your custom business object.
– Define the method attributes and parameters.
– Activate the business object.
- Release the BAPI
– In SWO1, mark the business object as released for your custom BAPI.
– This step ensures the BAPI is visible for external systems to call.
- Test the Custom BAPI
– Use SE37 to test the function module independently.
-You can also test the BAPI using BAPI Explorer (transaction BAPI), which lists all released BAPIs.
