Warning

CII-SR-232: Seller phone number should not have a URI field

In short

Warning: worth checking.

CII-SR-232 means the telephone block of the seller's contact contains a URIID element, which EN 16931 does not use there. It is only a warning: keep the phone number in CompleteNumber and remove the URIID.

What it means

In a CII file, the seller's contact telephone (BT-42) is held in TelephoneUniversalCommunication, in its CompleteNumber element. This rule warns when that same block also has a URIID element.

Why it matters

The invoice is still accepted. EN 16931 only reads the phone number from this block, so the buyer's software will normally ignore the URIID. If it held something the buyer needed, it does not arrive.

How to fix it

Check what the URIID holds. If it is the phone number, move it into CompleteNumber. If it is an email address, it belongs in the separate email element (BT-43). Then delete the URIID from the telephone block, or ask your software supplier to stop writing it.
