After executing the procedure you mentioned, the table /tmwflow/oldproj was filled but I'm still having same error related to
No maintenance cycle is open for the current system
IBase component is not a production system in system landscape
How can i verify a Mainteance Cycle is Open for that system?
Also, why does it says IBase component is not a Production system, BWP 500 is a Productive client
After checking Project Status, I found out its locked. I believe this is where the issue may be.
On Dolores blog, it mentions to check project being locked. I will check this and let you know the outcome
Thanks a lot for your help!
