What it means
An invoice line (BG-25) may name the thing it relates to, such as a meter point, a telephone number or a subscription. This is the invoiced object identifier (BT-128), written in the file as a document reference with type code 130. The check finds lines that have more than one such reference.
Why it matters
The format has one place per line for this reference, so with several the recipient cannot tell which one is meant. Because this is a warning, the invoice is still accepted and processed, but a stricter recipient may ask you to correct it.
How to fix it
On the line named in the check result, keep the one identifier the buyer needs and delete the others. If the rest still matter, put them in the line description or the line note instead. It is worth fixing straight away if the buyer uses that reference to match the line to a meter or subscription, and otherwise the next time you update your invoice template.
