Diagnosis
The source of supply check found that neither the external vendor &V1&nor the internal vendor &V2& entered are valid sources of supply.
The source of supply key for the material is "&V4&".

System Response
If both an internal and external vendor are entered, the sales pricecalculation function checks only whether the vendor entered is valid;it does not search for a valid vendor.
No calculation could be performed for material &V3&.

Procedure
If necessary, repeat the calculation without entering a vendor. Thesystem may be able to determine another valid vendor for material &V3&.
Alternatively,check the settings that are relevant to supply sourcedetermination, such as the source of supply key, the purchasing inforecords for external procurement, the supplying sites for internalprocurement, and so on.
