In a perfect scenario, MRP should leave a part number with an ending balance of zero, if that were the goal. In our case that is the goal.
We have a part number that, when viewed in time phase, has a negative ending balance because MRP does not appear to be generating unfirm jobs for future sales order demand. I’m also not seeing any error messages in the logs. It just gets to the date in question and moves on to the next date until it is done with the part.
I know this is probably not a simple answer to this question but any ideas why MRP would seem to “give up” after 5/26/2022?
MRP issues are always challenging. I’m not sure where to start… Did MRP actually finish? Do you have logging enabled? I refer to those often when something doesn’t look like it planned right. Often times I find that there is an issue with a BOM or I’ll find evidence of a timeout or some other “oddity”.
One that we often uncover through this method is subassemblies whose revisions changed and either no approved revision exists or the effective date is > than the job date. That typically only shows up for past due jobs, though.
I always use “MRP” and not “Basic.” I don’t know what Basic does (help file says it doesn’t do much, basically), so there may be more to the story than what you see @joerojas
Just run it for that one part and see what it says; shouldn’t take too long.
That’s a nice round number of 50 days. Any chance you have a parameter set for a horizon or anything like that on the part or in the site configuration?
Thanks for the idea Nancy. Unfortunately, there is nothing there that would explain this. There is prod prep time and kit time of 2 days each but nothing else.
