FX-SCH-A-000816: Keep at most one delivery electronic address block

In short

Error: fails the selected checks.

FX-SCH-A-000816 means your delivery party, ram:ShipToTradeParty, contains more than one ram:URIUniversalCommunication block. Keep at most one electronic address block for that party.

On this page

What it means

Under ram:ApplicableHeaderTradeDelivery, each ram:ShipToTradeParty may contain zero or one ram:URIUniversalCommunication element. This check counts the blocks, not the address values inside them.

Why it matters

The EXTENDED profile provides one optional electronic address block for the delivery party.

How to fix it

Check which electronic address you intend to provide for your delivery party. Keep its ram:URIUniversalCommunication inside ram:ApplicableHeaderTradeDelivery/ram:ShipToTradeParty and remove other occurrences of that block. Export and recheck your file.
