MRP Error_Abandon during process

KCoffin · March 31, 2020, 3:36pm

Hi, this my first post here. I wondering if anybody can help me with this MRP error. We run 5 processes. Last night 3 and 4 failed, however, the other processes (1,2,5) all ran and our Net Change MRP completed. Can you help me understand why these failed/abandoned?

From Basic Log:
01:06:06 Process 4 not responding. Abandoned during process ‘Defunct : Processing Part~X’
01:06:21 Process 3 not responding. Abandoned during process ‘Defunct : Processing Part~Y’

From MRP Log:

Hi Kerri, welcome aboard!

I am not a programmer, but the important phrase there to me is “Unable to get a lock on ShopLoad at (blah blah blah) Removelo at (blah blah blah) deleteUnfirmJob”.

To troubleshoot, I’d:

see if there are any unfirm jobs for those parts, and delete them; then
try to MANUALLY create jobs for both parts; then
try to MANUALLY schedule those jobs.

If those processes all work as they’re supposed to, then there may have been a timing issue and too many processes were trying to schedule things simultaneously, and these two blew up. Make sure you delete the jobs you created here, and then see if the same thing happens tonight.

If they don’t work, then you’ll get error messages at some point that should be more helpful (i.e. there is a MOM issue, there is a resource group issue, etc.)

Good luck!

Thank you Ernie!

Followed your suggested steps and MANUALLY created and scheduled jobs worked perfectly. We’ll see what tonight’s MRP run yields.

I want to close the loop here, MRP completed without any errors last night so I’m going to go with your suggestion - timing issue and too many processes were trying to schedule things simultaneously, and these two blew up - and move on. Thanks again Ernie!
