System is ignoring a existing PR in MRP

Hi all,

I'm facing a problem here when executing MRP.

System is ignoring a existing PR for a material and generating a new planned order... When checking the status in MD04 I can see the old PR with exception 07...

My problem is that this PR is old but it is being processed, therefore i want the system to consider it and not to create new planned order...

I've tried to change configuration of Plan.Horizon and Rescheduling it, but without success...

Can anyone please help me?
