New Batch Record Item Defaults No Longer Working

NORMAL: When entering a new Item Batch record from a Purchasing Receipt the normal functioning is that the Item Number is pre-populated in the Short and full page format.

ABNORMAL: Since a new field was added on the “Purchase Receipt Item” form the pre-population no longer takes place.

Below are snapshots of this action after the new field is added to the Customized “Purchase Receipt Item” in Row 80.

Any Ideas (on how to resolve) would be appreciated.
