How To Fix WU647 - Caution if changing supply source - prices already activated

SAP Error Message - Details

• Message type: E = Error

• Message class: WU - Promotion management messages

• Message number: 647

• Message text: Caution if changing supply source - prices already activated

What causes this issue?

You wanted to change the sources of supply for a promotion item for
which prices have already been activated.
The sources of supply assigned in the promotion are used in the
conditions once the purchase prices are stored.
A subsequent change to this data may mean that the promotion contains
inconsistencies, if, for example, purchase prices are activated for a
vendor and stored as conditions, but this vendor is not visible in the
promotion because of the changes made to the sources of supply in the
promotion. Also, no purchase prices are stored for the new vendor, even
though the activation status indicates that this is the case.

System Response

The source of supply is not changed.

How to fix this error?

First delete the activated prices. You can then change the source of
supply.
