We have a handful of manufactured parts that do not have jobs created for them when there is demand for the part. The parts are stock parts with valid revisions, and are defined similar to other manufactured parts with the same Product Group as parts that have jobs created for them. The parts do not have quantity in the warehouse. We’re at a loss on what to look for next in determining why these parts are not getting jobs created to make them. Does anyone have any ideas on where to look next for a problem?
Time Phase?
You’ll want to check the MRP logs, where you’ll likely find something like a material part revision not being found (i.e. it’s not approved), an inactive part on the BOM, etc.
Another option would be to try and MANUALLY create a job for the part. That will give you the same error you’d find in the MRP log, but without having to search through the MRP log (if it is indeed a revision-related issue).

I created manual jobs for a couple of the parts we’re having issues with, no errors. What’s weird is if you run MRP for just one of the parts, it creates jobs for the part and supply jobs for manufactured parts going into the one part.
In my experience this usually means supply/demand changed between the time MRP was last run and now.
I’d definitely go to the logs, unless you think there was no demand when your MRP run but then there was when you ran it individually (like @hackaphreaka stated above).
If there’s been demand all along, in my experience, there’s some error in the MRP log that was stopping it from creating jobs for that particular demand. The kind of errors that wouldn’t stop manual creation, but might MRP is things like the process getting locked on a part (if you have multiple processors running) or possibly even something like a server error.
Look at your MRP settings. Your cutoff date may be causing the issue.

I checked the logs for errors, found nothing related to the parts not having jobs generated, no lock errors. Cutoff date is currently 6 months out from the current date
Basic question… but assuming the demand is driven by a Sales Order… do you have need by dates? If not, MRP won’t know when to schedule them.
David, the job not being created are for component parts going into a product ordered from a sales order. The orders do have Need By dates on them.
Is process MRP checkbox is on in site/planning?
Are these pars that are made for a parent job, which MRP has created a job for?
Please post a screen shot of Time Phase for one of the parts in question.
Hi John,
Do you have schedule start date set also? Checking Dynamic/today here is important for our run to get everything and not have some stale submitted MRP date in it.

Jarry, I don’t see that flag in Site Maintenance → Planning
Start date is set to Tomorrow(Dynamic)
@Jarry is referring to the checkbox in Part > Site > Planning.
In this case (based on your Time Phase image)… open Part B66393 in Part Maintenance.
Is the Process MRP checkbox checked?
Just checked it, it is set…
