MVT 651 versus MVT 655

L.S.

Here at our customer we have a return process where standard MVT 651 is used. We want to have the option that goods, with quality, are posted using a MVT655.

At first we would like to create QM entries for this material, but the question is if this works when the system detemines a 651 movement. Is than automaticaly a 655used depending on the quality control parameter 06 in the quality view of this material?

Or is is better to modifiy the positiontype so, via the scheduling type, a 655 is defined via this.
