Changing Configuration Table to user maintenance table

Hi SDN team,

I recall that there was an OSS note that described the procedure to change a table in configuration to a user maintenance table. We have a scenario where the purchasing group table is maintained via IMG and the business process wants to maintain this as a master data table. Can anyone either walk me through the process of setting this up or point me to the OSS note that references this functionality?

Thank you.
