Item : Drawing number and Issue Number

We need Items to have Drawing No. and Issue No.

The Routing and BOM can be different depending on the Item’s issue number.

What is the best way to proceed?

Do we use Routing / BOM Versions for each Item Issue - but keep the Item the same?

If so, where would I put the drawing number for each routing version ?

Thanks

You can add a new field in the table or you can use any unused field available in item card(i.e. Description 2), unless you want the data to flow in the required tables.
