Creating a New Function Module in SAP ABAP
- To use the Function Builder, go to Development > ABAP Workbench > Function Builder on the SAP Menu.
- Form a Function set: A set of linked function modules is called a function group. “Create Function Group” may be selected by right-clicking on the “Function Groups” node in the Project Explorer. Please provide a descriptive name and unique name for the function group.
- To generate a new function module, right-click on it and choose “Create ABAP Function Module” from the menu. Give the function module a distinctive name and provide a short explanation.
- Describe the Function Module Interface: The interface lists the function module’s arguments and exceptions. Choose the “Parameters” tab in the Function Module Editor. Names, data types, and whether the parameters are input, output, or both should all be specified when defining the parameters.
- To put the Function Module logic into practice, go to the “Source Code” tab in the Function Module Editor. Write the logic for the function module in ABAP code. To carry out computations, get data, or communicate with external systems, use the parameter values.
- Function Module: Save and Activate: First, save the function module, and then activate it. This allows other ABAP applications to utilize the function module.
