I know about transaction CS20 to make mass changes to BOMs. However what I want to change is header data in a large number of BOMs. In other words, the point of entry for the change is not an item in the BOM, but the father materials themselves.
Is there a way to do this? I could use LSMW, but maybe there's a faster way.
I checked transaction MASS but there's no object for BOMs in there.
