SAP MM issue Relevant to Creation of PO from PR via ME57

Question

Hi
For a PR with Qty 1, Generally On PO can be created. (Take assigned PR)
But while processing through ME57 ,it is creating two PO's.
How ?
with one screen ME57 started and kept some where partially in the process of creating PO.
In another screen ,again through same me57 or ME59n ,processing the same PR and PO is created.
Now from the first screen , SAP is allowing to create another PO
Totally two PO's
How to rectify this error.
After creating PO's if we try for another PO means ,it is giving error that qty exceeded.
For your information,in our system ,we kept the message as warning which wont allow to create another PO.
What is the solution for this Issue.
Is there any OSS notes for this?
Below is the discussion for the same.
You mean , you are on the partial way of  trying to create PO through ME57 and your colleagues is  started processing same PR through ME59N.
After PO created by him, it is allowing you to create another PO also without error message.

JK: Yes, that is exactly what we did. I run open purreqs with ME57, started to make PO of one of them (=> takes me in to ME21N) but I didn't save PO yet. Meanwhile my collague runs ME59N and after it has saved PO for this purreq I was able to save PO for same purreq without any warnings.
Where as if you try after this process you could not able to process another PO against the same PR.?
JK: Yes. If I try to find this purreq with ME57 (or ME59n) it doesn't find it which is logical as PO(s) are already there.
Also confirm me from your experience  that whether is it allowed double POu2019s  when these transactions done separately  ? (not simultaneously processing the PRu2019s)
JK: From my experience I would say it is possible to create PO for same purreq if same purreq has been included in the original result and this "Update worklist" is not pressed:
This I'm not 100% sure and have not tested it but I'd assume so. If this update is pressed, it removes purreqs which have been turned to POseven if it is done by some other user.
Simply I can say the issue is because simultaneous processing of PRu2019s which allows creation of Double POu2019s.
Hope my understanding about the issue is correct.

Hi
I have set the Messages as you mentioned in SPRO and checked to create PR to PO.Still it is allowing to create.
Creating this messages will activate in Po relevant program ?
Because i am getting another Message 06-249 while processing PO for already processed PR. This message is coming from Program .But the same is not there the place wherre you asked to maintian me 06-254 and 06-248 (in SPRO).
Can you some more information about this.
