I want to set up Master planning for an item that can be produced in batches of maximum 8 Tonne or 12 Tonne respectively, depending on the Resource used. Currently my Route has two operations; Operation A is a mixing process with a run time of 0.05 hours per Tonne using one machine (currently set up with infinite capacity) and Operation B is a setting process that uses a container from a group of containers of either 8T or 12T and always takes 2 hours.
A batch capacity constraint is set up on the container resources and the ticks for Finite capacity, Exclusive and Bottleneck resource are all set to Yes.
However, when I run master planning for a 36T sales order, then 36T is scheduled for production as a single batch and all 36T is processed using the same 12T container, except the run time is multiplied by 3 (i.e. 6 hours).
What setup should I change so that this will result in 3 batch production orders that each go through the Mixing and Setting operations independently?
I think to split it up, you’ll need to adjust the formula size. I’m not sure anything on the route is going to split production orders into multiples…
Maybe two different BOM versions with different formula sizes would do the trick?
Hi Jake, thanks for your response. That is quite disappointing. I will look into the formula size option, however I am not sure if this resolves the issue. The company does not have a restriction on the batch size. So they could produce 3T and set that in either a 8T or 12T container, depending on what is available.
Is there a way to setup formulas so that, for example Formula 1 is for 1-8T and Formula 2 is for 8-12 T?
Well, you could setup the container used to use the plan group and priority fields, maybe, as referenced in this post https://docs.microsoft.com/en-us/dynamics365/unified-operations/supply-chain/production-control/substitute-items-bom-lines. That, in conjunction with using a from size on the formula, might get you what you need.
Hi Jake, is the link correct? It is about item substitutions on BOM lines.
Yes. It’s correct. The second section talks about substituting for planning purposes and mentions it can only be done when using formulas, not BOMs.
