We are using APB to schedule shop orders. Parts are manufactured in four processes on different work centres with the different sub-assemblies (manufactured components) identified as separate parts. The processes need to be scheduled so that they are completed in time for the next part to be started. We are backward scheduling and the top part’s need date should drive the scheduling of the previous (lower) parts in the structure. APB is not scheduling the shop orders of the parts as we had expected. How can this be achieved in APB?
+7Hi
In APB, we can do material planning only if they are defined as Finite Capacity materials. Generally MRP execution fulfills the material planning requirement (Including sub assemblies in your case).
However if you are keen to manage the material availability within APB, you can find this setting in ‘Inventory Part Planning Data’ window. In this window you can set Finite Capacity (If they have a lead time) or Always Finite Capacity for your sub assembly manufactured parts. With these basic data APB should consider the availability of those sub assemblies when you are scheduling your parent manufactured part shop order with specific Need date. To execute Backward scheduling you need to use ‘as late as possible’ scheduling option in scheduling dialog in APB.
And also make sure to use this Finite capacity materials option only when it is really essential. If you set all materials as Finite that may impact the performance of the Scheduling engine.
Thanks & Regards!
