How to change the quantity of a schedule (or to delete it) ?
We received 6 pieces of a material. (goods receipt done with movement types 103 and then 105)
Finally, we only need 2 pieces, so we used a type movement 122 to send the 4 useless pieces back to the vendor.
As a consequence, when I have a look at MD04, SAP expects the vendor sends 4 pieces again. (because 6 were requested for the schedule of the scheduling agreement). I wanted to change the quantity of the schedule (2 pieces instead of 6 pieces), but I'm not allowed to do it...
Do you have any idea how to proceed so that SAP doesn't expect any more these 4 pieces that we sent back to the vendor and that we don't want to receive any more ?
Thanks for your help and ideas !
