I'm struggling to make MRP/MPS provide WOS the way I need them. There are "leftovers" from work orders that the system will count as inventory and either give messages to reduce firmed orders or give wrong WOS. This product is good for that one week, after that it should not be considered for use.
Here is an example. I put in a weekly forecast of 10 for the finished product to be able to show the issue clearly. The semi-finished product has a technical lot of 102. What I need to see is a WOS for each demand here because the product is only good for that week. This is running through MPS with only weekly buckets.
I had hoped that enabling Lot management and setting Recontrol/Expiration would do what I want, but it didn’t.
In contrast, here is a purchased product that is set to run through MPS. Here it's suggesting an order of 100 (the technical lot) for an MWF of 10 and then not considering the extra 90 for the next MWF of 12 and suggesting another order. This is how I'd like to get WOS functioning.
Any thoughts on changes to settings or parameters to address this?
