About BOM line validity
Dynamics AX 4.0
BOM lines can be valid or invalid, depending on the validity dates specified on the BOM lines. This is useful if you need to assign a different item number to a BOM version for a period of time.
For example, you might want to substitute a frosted lampshade for the standard white lampshade in the lamp BOM for the month of May. Or, if the sub-production required for a BOM version is not available, you might want to use a replacement component from the vendor instead.
