In this IMG activity you store texts to be used for the letter header, the letter footer, the address in the letter window and the signature line that are to be used for the credit memo which was created using the ERS procedure. These texts are company code specific. You can use the ERS procedure from the "normal" invoice verification or that of the logistics invoice verification. If you use the logistics invoice verification ERS procedure, standard message determination is used to produce the credit memo output. The message determination must therefore be set. To set the message determination, choose Materials Management -> Invoice verification -> Message Determination in the
Implemention Guide.
