Add Validation to 850 Component UPCs

EDI -> Incoming -> EDI Purchase Orders

Release 28_3, 29_0

A validation of the 850 component UPCs have been added. This is applicable to 850s where the prepack lines are processed instead of the component lines, as in example below.

When updating the EDI order, if one or more of the component UPCs is incorrect, an error will be displayed and processing will not be allowed.
