I am trying to implement Global Scheduling in order to automate some of our daily job due date changes/rescheduling. I have an MRP process that is running every night, and creating job change date suggestions. These are visible on Planning workbench and Time phase. For some reason Global Scheduling will only reschedule jobs that are “Make Direct”, the “Stock” jobs will not reschedule. I have done many tests on this, company configuration allows job change with demand change, and there are no locks in place. The jobs listed are engineered and released. We also use infinite resources and are backwards scheduled.
Is there anyone who has been through a similar issue with Global Scheduling?
Thanks for the Reply,
We do allow scheduling before today, and we do globally schedule started operations.
In my testing of global scheduling the jobs are engineered but have not yet had any MES labor transactions.
Since the demand is make to stock and probably coming from a min/max and you allow scheduling in the past, those jobs will never reschedule. The demand date will never change because there is nothing to change it like on make direct jobs. Turn off allow scheduling in the past if you want them to move.
I unchecked the “schedule before today” checkbox and reran MRP, Global Sequence order, and Global Scheduling. I am left in the same boat. The planning workbench suggests I move the stock jobs to the correct dates, but global scheduling will not reschedule the jobs to those dates automatically. The test part I am using does not have any min/safety/max so I am unsure as to why they will not move.
Is there a different process to execute all planning suggestions from MRP?
I think to really test it, you would need to remove all Jobs from the schedule and then re-run everything. I have found in the past that Jobs that are already scheduled will stick in the schedule with their original settings. Removing them from schedule is the only thing I have found that clears all that out.
To anyone who reads this now, it turns out there was an issue with the GS running in the Pilot Environment. The next release corrected the issue and we have been successfully running MRP then GS for about a year now with no issues.
As a side note changing MRP to only run through 8 Months of Forecasted Job planning shortened the MRP run time from 2 hours a day to 30 minutes for a Net Change and from 4 hours to 1.25 hours for a Regen.
