Hi Jelena,
Here is a scenario,
We have a DDL running which creates different jobs based on certain criteria (which could be shipping point or sales organization), now if we have sales order that is large (more than 50 Items), it will take some time to confirm and process so entry is there in VEPVG table. Since batch job is running for every hour if this order was picked by batch job during last minute, then the next job also will start and will pick this order since this is not locked.
This is happening frequently while we run batch jobs for DDL and this causing an issue for the batch job to fail or error log generated.
I hope you understand the issue now.
Thanks
Raj
