Hi 

 

Attached is an example of unexpected results in apb.

Shop order 903 is the parent shop order 1000 Disc and spindle is the child wanted for operation 10 of 903

Both parts are finite

Result from APB puts shop order 903 finish date ahead 1000, This is a physical impossibility

What do we need to do to make sure the parent SO uses the child part for its planning?

Thanks

If you define the component (Disc and spindle) as a finite material or Always Finite (Schedule Capacity in Inventory Part setting), then that will be added as a constraint when scheduling the parent part, i.e. the component needs to be available before the parent can be scheduled! 

Schedule Capacity

Specify whether the material is to be calculated with Finite availability (limited within a fixed non-zero lead time, or always limited) or with Infinite availability (unlimited) during operation scheduling with IFS Advanced Planning Board (APB) or Work task scheduling with Maintenance Planning Board (MPB)
