Job Over Run

I am curious how you all handle this situation.

We setup a job to make 10 parts. The first operation happens at the saw, and he cuts up the blank he has been assigned and it makes 25 pieces. Those 25 parts go through the rest of the operations, as it makes more sense to run them all then just do the 10 we need.

In this case, do you go back in and adjust your job run qty somehow, and then reschedule everything so it knows you are now running 25 parts?

We don’t do that, and instead just overreport the amount completed at each op. This results in many ops having more completed parts than run parts.

You can add an overrun qty to the job / add a secondary demand for inventory of 15 (if that’s where they ultimately end up).

Then do you reschedule the job so that the operations are booked for the right amount of time for 25 parts?

We experience this as well (in both directions, unfortunately). We are strictly make to stock.

The correct thing to do is to adjust the job to reflect the correct actual and expected yield in addition to reporting your quantities accurately.

Lately we have been talking about the Production yield Recalculation process to adjust jobs automatically.

Well, we don’t really use Epicor for scheduling (yet)… but I would imagine that would be best practice to keep your board synced up.

I’m with you there!

I have looked at this in the past. Is it difficult to setup, and does it really do it all? I can see how it could adjust the quantities but will it reschedule the job/ops?

We aren’t using it yet but as far as I am aware it will only adjust quantities. There is a separate process to reschedule operations.

Have you gone any further into this? We are looking for it to adjust upwards for Subcontracting to have the correct number driven to the suggestions, but it seems like Production Yield Recalculation Process only adjusts jobs downward.

edit: added link to idea.

I think there are tons of legit scenarios where the Production Yield can/should adjust quantities upwards. If you agree, please add your votes to the idea.

In the meantime, I think the best you can get out of this canned process would be to enable the alerts and the over production variance. It won’t actually make an adjustment, but it can trigger an alert and then you can go fix the job.

I have not looked into designing a custom solution as of yet.
