Step5: Place this Function Module in to BOR using the T-code SWO1. Provide the name of the object and press create button.

Provide the following details.

Step 6: Add our Custom BAPI using Utilities->API Method->Add Method

Now, Provide the created Custom Function Module name and click enter.

Press the Next Step Button.
