In short

On this page

What it means

Each ram:TelephoneUniversalCommunication inside ram:DefinedTradeContact of ram:ProductEndUserTradeParty must contain exactly one direct ram:CompleteNumber child. This rule does not check whether the number text is empty or correctly formatted.

Why it matters

The Extended profile requires one number field within each of these contact telephone blocks.

How to fix it

In your CII XML, check ram:TelephoneUniversalCommunication inside the product end user's ram:DefinedTradeContact. Add the missing ram:CompleteNumber with the contact's phone number, or remove extra number elements while keeping the correct one. Export the corrected file and recheck it.
