Activation Error

Hello,

I copied some transport resuests from one SAP system to another, but when trying to activate some of the objects I get the following error message:

I guess the problem is in the BADI implementation OT_DESC_CHECK_MOA.

But now, whatever I want to do I always have this error message appearing (when trying to delete the BADI Implementation or to create a transport request or activating an object or anything).

I always get this error message.

Please help me solve this problem.

Thanks in advance.
