How check table update program, FM etc..

Hi ,

I need to prepare a document for table the KNB5, the table contain 11 fields, need to prepare a document for all the fields how they are updating and what Programs, Fucntion Module, Module Pool/enhancement etc.. involved for table updating .

I will use where used list for each field and get list programs, Fucntion Module, Module Pool/enhancement etc. involved but in what basis, I will confirm weather this program or FM really using table updates or not.

Shall I search with update command or with table? is any other way?

Thanks in advance.
