How To Fix WV281 - Internal supplier &1 is not a permitted source of supply

SAP Error Message - Details

• Message type: E = Error

• Message class: WV - Messages about Sales Price Calculation

• Message number: 281

• Message text: Internal supplier &1 is not a permitted source of supply

What causes this issue?

The source of supply check has found that the internal vendor &V1&
entered is not a valid source of supply.
The current source of supply key "&V3&" (internal procurement before
external procurement) means that the system checks the internal vendor
entered first. If this vendor is not valid, the source of supply
determination checks for external vendors. In this case, the system
found internal vendor &V4&.

System Response

No price can be calculated for material &V2& with the restrictions
entered.

How to fix this error?

If necessary, repeat the calculation using vendor &V4&.
Alternatively, check the settings relevant for supply source
determination, such as the source of supply key, the purchasing info
records if using external procurement, the supplying sites if using
internal procurement, and so on.
