I have change number ECM1 which is valid from 10.04.2016. I have added 2 material A,B in a bom with the same cn.
Now I have created another cn ECM2 which is valid from 23.04.2016. I replaced material A,B with C,D with the 2nd cn.
When i display my BOM at present date material C and D only visible. Now I am creating a planned order in current date, in component list
both A,B against cn ECM1 and C,D against cn ECM2 is visible. Why A,B is still appearing in component list?
