Because there will be changing requirements for the materials subjected to Net Change, the proposals generated after MRP have to be updated.
If proposal line info of the materials has not changed, these lines are updated by new values. If there are new requirements belong to different delivery dates, new lines are added to same proposal slip.
If there are delivered lines, "While deleting MPS/MRP/CTP if there is a transaction with unchanged status" (break relations / slips will be deleted) parameter is considered. If "slips will be deleted" option is selected, related material lines are deleted in delivery slip. If only this material is take place in slip lines, the slip is deleted too. If "break relations" is selected, the slip line relations are broken for the materials.
However, the slips of which status info has been changed are not updated. If the change in plan increases the requirements, a new slip is generated for the missing amount.
