Sales/Credit Orders

How do we apply Security to Sales Orders / Credit Orders in the P4201/P4210  ( Xe 7.333 )

Row Security has been considered, however the Sales Order Type 'Item' was never set-up in Data-Dictionary for Row Security use.

The general advice is NOT to change Item Settings in DD, as should be decided at implementation.

Can we set up Order Type Item in DD for Row Security Use and Apply Accordingly.

Or is there another way to lock users out of Sales Orders / Credit Orders ?

All Advice Welcomed.
