Hi all,
I’m currently experimenting with the scheduling and MRP modules in Epicor 10.
Since our company used EPICOR for a while without making use of those features, I had to create a whole new set of operations and resources to hopefully get isolated from the previous setup.
I’ve been encountering large gaps in the schedules (see captures attached, between march 8th and 15th)
We use finite scheduling on all resources and haven’t configured any material constraints, setup times or move times.
This job was scheduled using backwards scheduling.
Has anyone experienced similar issues or can give a hand?
Only thing I would check is that you actually have enough work in the system to fill that gap. Since you are backwards scheduling, you might be viewing the truth in that with the current demand you don’t need to start working until late March. Have you tried forward scheduling to see what happens?
I’ve tried forward scheduling and the gap is still present.
Following up on the theory that there’s not enough demand for work, i’ve set up a second identical job with a required date of the 20th of march. The gap is still present in both jobs (see image)
And you’ve regenerated the Shop Capacity data?
And you’ve checked all of the Calendars - Company, Resource Group, Resource, and Employee? (because there is a hierarchy to the calendars)
Are you utilizing Capabilities? Having multiple resources with a capability only works correctly if you give them priority values - or something like that.
We’re just getting to this same point and have gaps like this too, although we think it’s like @jkane said - not enough work to fill the gaps at the moment since we felt like our lead time was much greater (so our promise/due dates are way out there) than the Scheduler seems to feel.
Concerning calendars, i’ve set our standard production calendar to the resource groups and left the resource calendar themselves blank. Employees aren’t linked to resource currently.
We are indeed using capabilities. Some priorities were set to 0, bumped those to 1 without any change in scheduling.
Concerning the Shop Capacity data, I’m currently checking with our Epicor admins to see if it’s part of our nightly process run, will come back with an answer.
@CParadis There is a scheduling log that may shed some light on why it is not scheduling ops back to back. KB0100390 at the link below goes over the steps.
Thank you, I’ll try to get one of our admins to send me that log to check it out.
Edit: Sadly, the admin came back saying they don’t have access to the epiccare forum.
After some more testing and investigating, we realized we had a stray material that had the material constraint field checked. That coupled with the close due date seemed to have created the weird gap in scheduling. Removing the constraint on that part fixed it as far as we know.
Thanks for the help!
