- Goto > Function Groups > Create Group
- Function Group name should start with ‘ZBAPI_’ e.g. ‘ZBAPI_PIS_ORDER_LIST’
- Each BAPI needs to have its own Function Group
Create a new Function Module via SE37
- Function Module name must include the keyword ‘BAPI’ e.g. ‘BAPI_PIS_ORDER_LIST’
- Set the Function Group to the one created above
- You will see the warning Function Module name is reserved for SAP which means the name of this Function Module can not be altered by future development
- Selected Remote-Enabled Module in attributes to allow the Function Module to be invoked via RFC
- Import/Export Parameters can only be BY VALUE for RFC enabled Function Modules
- Structures for use in BAPIs should include the keyword ‘BAPI’ e.g. ‘ZBAPI_PIS_INPUT’
- Add the relevant Source Code, Save and Activate as usual
Release the Function Module via SE37
- Function Module > Release > Release
Create the API Method using the BAPI Wizard via SWO1
- Object Type should be prefixed with ‘ZBAPI_’ e.g. ‘ZBAPI_PIS’
- Set the Object Name, Name and Program to be the same as the Object Type
- Provide a relevant description and set the Application to * (cross-platform)
- Utilities > API Methods > Add Method, enter the name of the Function Module created above
- Provide a relevant method name and description, click the black arrow twice then click Yes when prompted to automatically generate a new template for the not yet implemented method
- The newly created method should now be available under Methods
- Select the name of the BAPI at the top of the screen:
- Edit > Change Release Status > Object Type > To Implemented
- Edit > Change Release Status > Object Type > To Released
- Select the new API method under Methods:
- Edit > Change Release Status > Object Type Component > To Implemented
- Edit > Change Release Status > Object Type Component > To Released
- Object Type > Generate
