Have you ever received a request from the business to have some changes in the Sales Order Entry (P4210) form, to make it friendly for the user? Or from the buyer who have to deal with lots of purchase orders everyday and could perform their job faster and easier if an specific screen only displays the data they are interested to see?
You can make that available to the user with not much work and no customization required at all. The answer is in Personal Forms / Defined Queries. You will find more details in Understanding Personal Forms Available in 9.2.1 Tools Release and Newer (Doc ID 2204303.1). Make the difference for your business today!
