Quantities are not taken into account for blanket purchase orders or purchase orders for services, for which the services-related invoice check is not active. However, in certain circumstances, a negative value can be calculated for particular quantity fields (for example, BPREM). This negative value then generates the DYNPRO_CONVERSION short dump if the Table Control View is issued on the item list. Additional key words
