Adding new field in GLU1, require to add in GB01 also?

Hello Experts,

We have a requirement and to meet that, we have to add a new field in GLU1 table structure. Idea is to add it in transaction table without adding it in summary table.

While the program makes Finance posting, it calls GB01 Tcode to make posting and stores data in SPL table.

Now, the question is: do we need to necessarily add a new field in GB01 front end and map it to new field in table, in order to make posting and update value in new field?

We dont see any screen exit provided to add new field in GB01.

Pointers/ guidance in this regards would be much appreciated!

Best regards,

Karan
