I need some help for this special case.
Consignment fill-up was done out of plan 1110 for customer 4711.
Now the consignment return has to be done to a different plant 1120.
SAP doesn't allow this case right now by providing the following error no. "M7185".
Thank you for help to get this solved!
As you should be aware when you create a return order referencing the parent billing document, all data would be copied to target document and this includes the plant also, which you cannot change.
What you can do is that you create a separate storage location for returns and take the stock into that storage location in parent plant. From there, you can transfer the stock to a different plant via MB1B with movement type 301.
On the other hand, if you create a return sale order without referencing the parent billing document, then it is possible to receive the rejected stock into a different plant but this is NOT adviceable.
