Hi,
If the message is hardcoded , then you can not change through configuration, same message has been hardcoded in our version:
* Only give error message if companycode overall bookings are not OK!
IF sy-subrc <> 1. "STFO590431
PERFORMmessageTABLES e_messages
USING c_msgid_pb 'E''497'
p_text p_object p_obj_data-bukrs p_bukrs
CHANGING p_maxrc.
IF1 = 2.
MESSAGE e497 WITH p_text p_object p_obj_data-bukrs p_bukrs.
ENDIF.
If the message triggering in your case..It is not possible to change through config..you need to check with SAP by raising OSS.
Thanks and Regards,
Chandra
