When using procurement categories in purchase requisitions, the delivery address used comes from the preparer's employee file. It forces to re-enter business addresses of the company on the employee level, which for us is data duplication. on the purchase requisition line, the system has all the data )Legal entity-site-warehouse) to identify the correct delivery address. This is particularly essential for users that cover multiple sites. A good example is an health and safety supervisor, which oversees multiple warehouses and orders special equipment for multiple locations. 

It also happened that the purchase order was created with the employee home address.

The suggestion is to have a single parameter to define whether to use employee address or warehouse address. Catalog items already use the warehouse address.
