What it means
In the Extended profile of Factur-X and ZUGFeRD, ram:SalesAgentTradeParty may contain zero or one ram:URIUniversalCommunication. The test counts these blocks, not the address text. This is the sales agent's electronic address, not the seller's electronic address (BT-34).
Why it matters
The profile permits at most one electronic address block directly within this sales agent block. Multiple blocks exceed that limit, even if they contain different addresses.
How to fix it
Check the electronic address you export for the sales agent. Under ram:SalesAgentTradeParty in ram:ApplicableHeaderTradeAgreement, keep the intended ram:URIUniversalCommunication and remove the extra blocks. Do not change the seller's electronic address (BT-34) to resolve this rule. Check the file again.
