What causes this issue?

The delivery number in segment &V1& (segment number &V2&) can not be
explictely assigned. The delivery number is interpreted as an external
delivery number of a delivery that should lead to your system with the
partner identification along with a reference to the delviery. This
reference ist not specific enough because several deliveries with the
same external delivery number and supplier number exist in your system.
