Hi Arnulfo
I think you should you decide which fields would you like to consider for updates.
You can create small program using similar program/FM used in MASSD.
For example, in our case we would like update the deletion flag in MASS for material location, so we have created small program with selection screen but internally called MASSD logic to update the data. It´s kind of small raper program with selections screen.
Request you to please check from your side and let us know if this information helps you.
Thanks
Amol
