I want the validators of purchase orders to receive email notifications to validate the PO according to the classemnt of the validator in the validation circuit.
So, I found that I have to activate the workflow and add sending by email in the transaction 'SWDD'. (Workflow : WF_PO_REL)
My problem is that I did not find the variable that I have to put in 'expression' for the validator who receives the mail.
Currently the creator of the order that receives the email because the variable put in the field is '_WF_INITIATOR'.
