I am using ECM for BOM change.I am creating change number through CC01 and also maintaining the material code in Object type
material BOM with plant and usage.But when I am changing BOM with refrence to change number syatem is asking me valid from date . After entring valid from date also system is not allowing me to enter in to BOM for changes.Already I have maintained valid from date for change in CC01.Also I am using ECR without release key.Further the system status is created which is not editable.
When I am comparing same BOM with two different change numbers in CS14 system is throwing error BOM not processed with Engineerin change .
My requirement is I am creating Engg BOM with usage 2. After some days I have to do changes with amendment number, I should do with refrence to change number only .I need to compare original BOM with changed BOM in CS14.Secondly I am copining same item components partially for production BOM with usage 1.Change should reflect in production BOM also.
