Diagnosis
During supply source determination, the material named in the message,in the plant named in the message, is assigned a source of supply whichdoes not match the item category of the material.
In the allocation table, the item category of the material controls howthe material is procured and delivered to the plants.

Examples

• Procurement from an external vendor and delivery via a distribution
center

• Order placed with external vendor for direct delivery by the vendor


• Delivery from the distribution center without external procurement

Different item categories may also be needed to differentiate betweenthe type of delivery document for deliveries from the distributioncenter (e.g. stock transport order, delivery without purchase order).
Depending on the item category, selection of a vendor is limited. Forexample, a distribution center cannot be entered as the source ofsupply if the item category is 'third-party delivery'.
