Message for PR creator

[Márton Zsolt]

Hi all,
We are in ECC 5.0
My task is to send a receipt message for a specified user (ex:purchase requisitions creator) when a good receipt is carried out. Int he MM there is a standard way to issue a message to the purchase order creator, but not for the requisition creator. Is there any way to add additional reciviers to a message in transaction NACE (Message contorol) or do I have to set up a workflow to fulfill my problem?

Thanks in advance
Zsolt
