Create the API Method Using the BAPI WIZARD

The BAPI wizard is used toTo expose the remote function module as a BAPI. The wizard will generate some additional code, so the function module is a valid method of the BOR. This allows the BAPi to be called as a workflow method in addition to be called by an outside program.

Note: Each function module corresponds to a method in the BOR

Go to the Business Object Builder SWO1.

You can either create the new Object type as a subtype of an existing business object or create a new business object from scratch. In this example it would be obvious to create the Object type as a subtype of BUS2005 Production order. However, to illustrate how to create a new Object type from scratch, we will do this.

In the Object/Interface type field write the name of the new Business Object: ZORDERSTAT. Press enter and fill in the additional fields necessary to create the object type.

Supertype: Not relevant because we are creating our object from scratch

Program. This is the name of the program where the wizard generates code for the Object type, NOT the function module we created earlier. The program name must not be the name of an existing program.

After you have finished the wizard, you will notice that the ZGetOrderStatus has been added to the business object:

You can double-click on the method to see its properties. To use the business object you must change the Object type status to Implemented. Use menu Edit->Change releases status->Object type->To implemented. No you can test the object (Press F8).

Note that the BAPI wizard has added a wrapper class for the function module so it can be sued as method in the business object. Choose menu Goto->Program to display the program:
