Important notes:
- Each BAPI must have its own function group.
- Under the attrbutes tab remember to select Processing Type Remote
Enabled module, otherwise the function module cannot be invoked via RFC and
used as a BAPI
- Import/Export parameters can only be BY VALUE for an RFC enabled function
module
- We are only creating one BAPI in this example, but you can create related
BAPIs in the same function pool, so they will be able to share global data.
Code
Notes:
- The subroutine SET_RETURN_MESSAGE is a standard routine used for BAPIs that
use the BAPIRETURN structure
- In form Z_BAPI_GET_ORDER_SYSTEM_STATUS there is a test IF 1 = 2. If
the test is true a mesage is displayed. The condition will obviously never be
true, and we will never want to display a message in a BAPI. The reason why it
is included is, that it create a reference for the message, so that the WHERE
USED funstionallity can be used for the message. This is the SAP standard way to
handle it, copied from the Company Code GetList BAPI.
