Suppressing Transaction Type and Transaction Category Description

Hi,

We need to remove transaction type and category description centrally, which is applicable to all user, we tried to control by personalization keys but it works only for user level. Kindly suggest.

Want to see only Transaction type description for all users.

I have referred the following thread but that is application for single transaction type but in my case I have two transaction types under Business Activity.
