I think the behavior of Vantage's MRP engine is to delete any unfirmed
jobs whose ID begins with the Unfirm Job Prefix as defined in the
Company config under Modules/Production/MRP that it thinks needs to be
deleted:
02:00:01 MRP regeneration process begin.
02:00:01 PID: 12104; Session:
192.168.12.32::MfgSys803::8301::6808e3704c6ba51c:a1807c:12b6961b93d:-2f9
1
02:00:01 Generating plant list.
02:00:01 Starting sub-processes
02:00:01 Deleting unfirm jobs ...
02:13:05 Scheduling jobs ...
02:13:07 Building PartList Level: 0
02:26:08 Building PartList Level: 1
Here's what the MRP Technical Reference Guide says on p.68:
By default, the MRP engine will create an unfirm job if it can find a
valid method of manufacturing linked
to the part. However, if the MRP engine cannot locate a valid part
method, it instead generates a job suggestion.
You can convert the job suggestions to firm jobs within the Job Manager
program.
Even though you can convert an unfirm job or job suggestion into a firm
job, these jobs will continue to be
modified each time the MRP engine is run. This is also true for open
purchase orders that were originally
generated by MRP. The MRP engine will generate suggested changes to open
jobs and purchase orders,
which you can choose to act on.
Note that the MRP engine will use the Unfirm Job Prefix value to
indicate which jobs were generated by
the MRP calculations, and that these job numbers are generated in
sequence. You can review the jobs
within the Job Entry program. As long as the job has an Unfirm status,
it can be deleted by the MRP
engine and regenerated as a new unfirm job.
If the MRP engine is run against a firm job, you can limit the
suggestions placed against it. You can freeze
a firm job's Due Date or Quantity by selecting the appropriate Lock
check box. The MRP engine cannot
make suggestions against locked values. Locked values, however, are
still evaluated as part of the MRP
calculations in order to determine the total supply available against
the current demand requirements.
