Diagnosis
The detail screen "Goods movements" was called already. Due to asubsequent change to the date "Execution Start", the material for thegoods issue and goods receipt are redetermined. Changes made forindividual materials and for unplanned goods movements are lost.
If more was confirmed than was planned, there is no requirement for thefollow-up material for a part to be discontinued, so the systemcompares the "Execution Start" date with the effective-out date definedin the material master. If the effective-out date has been reached, theadditional quantity is taken from the follow-up material, otherwisefrom the part to be discontinued.

System Response
The goods movements must be redetermined for every date change, sinceat this time the system cannot determine whether there are parts to bediscontinued in the goods movement overview.

Procedure
Check the goods movements again and, if necessary, change or add to thegoods movements before saving the confirmation.
