Diagnosis
Several assignments are assigned to this purchase order item through theprice-shop report.
At least one store is contained in 2 or more assortments. Because eachstore can only be assigned to an allocation table item once, however, aseparate allocation table item is created for each assortment.
As a result, several allocation table items now exist for this purchaseorder item.
Synchronization between the purchase order item and the allocation tableis not possible due to this multiple assignment.
