New to BAPI

Purpose: I am trying to create a new BAPI to generate a list of Flight Customers that will display both Customer ID and Customer Name using FlightCustomer Business Object type.

BAPI name: Z_BAPI_GET_CUSTOMER_LIST

Processing type: Remote-enable module

Can I define a reference type?

I am getting an error message of 'Reference Parameter are not allowed with RFC' when trying to define the following EXPORT parameters:

Parameter name: RETURN

Type spec: LIKE

Reference type: BAPIRET2

Pass type: no

Short text: Return parameter

Please advise. Thanks in advance.
