Re: minus values in BOM

Dear Marcin,

I guess you want to know the life of a mandrel during production order execution.

In my understanding this mandrel can be created either as a Material PRT /equipment PRT and assign

it to the operation in the routing where it is required and not in the BOM.

Also the life of PRT/PRT availability is not taken into account during Materials planning.

Check if this link can help you,
