Question:
hi guys,
I have a scenario where i have created an message class object called Z1 in DEV and pushed it across to QA/PRD. The transports went thru, however, fatal errors have occurred (error 08 in transport log) stating that you can not modify a standard SAP object! But the object created is Z1 and is in the customer namespace! I looked in PRd and have found that the message class Z1 seems to have been created directly there for some reason and has a local development class $TMP. Can anyone shed some light on this dilemma?? Is there any way to check the change logs on message classes?
thanx
Answer:
Use SE91 to display message class and find out who changed/created it.
