Required Long Description field from item master in Purchase Order Lines editable.

Hi,

We are looking for the functionality to call Item Long Description from Item Master into Purchase Order Line. Based on Item Code entered in PO we need that Item's Long Description with editing rights at PO Lines so that the user can modify the long description as per his need.

The actual requirement is that one item code can have several specifications. The specification for the Item code is loaded in Long Description at Item Master. We want to call this Long Description field into Purchase Order line based on the item code in purchase order with editable functionality.
