Runtime error while executing TCode due to inactive Structure after SPDD

Getting following error while executing Tcode:

"The current ABAP program "SAPLEINR" had to be terminated because it has
come across a statement that unfortunately cannot be executed.
In include "LMEPRU34 ", in line 450 of program
"SAPLMEPR ", the following syntax errors
have occurred:
The data object "LS_KOMP" does not have a component called "MBLBU". "

I can see two versions of KOMP structure one which is 'active' and other 'modif'. we need to activate the modif structure which was probably not activated after SPDD. Any ideas how can I achieve this?

While activating in SE11 its giving error. So how can I activate the SPDD modified table and make it in use not the active version.

Thanks.
