[Erp5-dev] Packing list Arity

[Leonardo Rochael Almeida]

This means that, for some reason, you have more than one "causality"
relationship (category) in your Sale Packing List (SPL), or perhaps in
a "Sale Packing List Line" of this "Sale Packing List".

Check in the "Metadata" tab of your SPL or its lines.

Cheers,

Leo
