Reservation during OCM

Hello All,

I am changing BOM and routing after the creation of production order using OCM. When I add one or more components its working fine and components get added in same reservation number. But when I delete one or more componemts from BOM and doing all the steps in COCM, it is not get deleted from production order. Its still showing under the same reservation number.

Also when I do CO11N it is showing the deleted components and not showing the added one. Every time I have to add the newly added components and delete the deleted components.

Please suggest the solution so that system should delete the removed components and show added copmonents during co11n.

Regards,
