MRP Business Logic Error JobEntry.dll

,

Hi all,

recently, on different times, the MRP process goes in error.

If I go in the log files nothing about the error is written, there is only a log in the event viewer that says:

“An error occurred trying to run a sub-task:
Business Logic Error
Business Layer Exception
BusinessObjectException
Description: Update not allowed, Job Not Firm.
Program: Erp.Services.BO.JobEntry.dll
Method: valPreventChange
Line Number: 6035
Column Number: 29
Table: JobAsmbl”

Ok so from my knowledge the only Not Firm jobs are the MRP*** ones, right?
In the MRP log I see that the process ‘Saving load for job:’ touches every MRP process without errors.

Every log file ends with the classic ‘MRP process done’ or else, no errors…

How can I discover what is the job (or operation) the MRP is trying to do before the error?

Thanks in advance

Did you try running the MRP with Logging Level set to ‘MRP and Scheduling’ ? It should give you more details.

Hi,
the log is already set that way. It doesn’t say anything regarding the error.
Again the only thing written is in the even viewer regarding updating a non firm job.

It just happened this night and the MRP went in error…
