The SAP error message SEEF_BADI074 indicates that there is a missing class for a Business Add-In (BAdI) implementation. This typically occurs when the BAdI implementation is trying to reference a class that does not exist or is not activated in the system.
Cause: Missing Class: The class that is supposed to implement the BAdI is either not created or has been deleted. Incorrect Implementation: The BAdI implementation might be incorrectly configured or pointing to a non-existent class. Transport Issues: If the BAdI implementation was transported from another system, the class may not have been included in the transport request. Authorization Issues: Sometimes, the user may not have the necessary authorizations to access the class.
Solution: Check Class Existence: Go to transaction SE24 (Class Builder) and check if the class mentioned in the error message exists. If it does not exist, you may need to create it or restore it from a backup. Check BAdI Implementation: Go to transaction SE19 (BAdI Implementation)
