PR release procedure no longer working-error MEPO 822

Question

I've raised a message previously regarding PR release problem. Now i've found something that need expert helps to clarify on this.
Situation :
One of my client(ABC) implemented release procedure for PR which is not assign to value limit. It is by document type. They had 2 document types; NB and RNB.
  NB = NOT subject to release
  RNB = SUBJECT to release.
So when they :
create a PR with document type RNB - it will goes for approval.
create a PR with document type NB - it will not go to approval.
It was working fine until after they created a new document type which copied from NB, called ZTP.
  ZTP = NOT subject to release.
They did not touch anything on PR release configuration. However, the release has no longer working. Means, when they create PR with document type RNB, it will NOT go for approval as it suppose to. I've check in configuration, all are fine.
Findings:
I've created a PR, and go to ME45N to release it but system prompt me an error message
"Purchase requisition 10000066 cannot be released". I check on the message data,  the error coming from MEPO, message number 822.
So i check in OSS and found a note which is similar to this case.
Note 939371 - Overall release PR using ME54N gives error MEPO 822
Link : https://websmp230.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=939371#Text
But my question is,is it also applied to ME51N and without external application as per my client's case?
Please anyone help.
Thanks.

Hi guys!
Wants to share something. I had a problem to release my PR. When i want to release PR via ME54N, system give me error message "Purchase requisition 10000066 cannot be released". When i checked message data, it is coming from MEPO Messafe 822. So i asked SAP, they said this one is caused by different issue. Here's the reply from SAP.
Here's the reply from SAP :
Purchase requisition 10000066 cannot be released
Message no. MEPO822
Now click the other requisition button and let say
choose Purchase requisition 10000068,
Execute ME54N again:
Purchase requisition 10000068 cannot be released
Message no. MEPO822
Comment/explanation:
The log incidence seems not having problem with release
strategy as it was ok but it was the last PR was called
everytime ME54N was called. This same as it works in enjoy
transaction ME21N/ME22N or ME51N/ME52N.
For example, When using ME21n or ME22n to create or change PO,
after saving the PO. There are 2 ways to exit the transaction,
1, enter another T-code or use /n to exit directly.
2, use 'F3' or the 'green tick' to exit ME21n (or ME22n)
Then you can access ME23n to see the difference.
For the 1st way, ME23n won't display the last PO created in ME21n
For the 2nd way, ME23n will display the last PO just created!!!
Please see attached consulting note 595627 that explains a new
functionality as of release 470:
Due to performance problem, a decision had to be taken about the way to
use transactions. If you leave transaction ME21N/ME22N via the
exit button (F3), the expected PO will be displayed next time you use
these transactions. But if you quit abruptly (/nXXX) the PO number
won't be saved for the next transaction ME2?N.
As SAP note is the official document to explain system behavior,
this document is provided by SAP developement to explain this system
behavior to customers.
In your case, you had used ME54N and this was same as you use ME53N.
The last PO always display. You may try to view Purchase requisition
with release strategy, for example Release group R1, Rel. strategy
R1, then after this execute transaction ME54N again, the message
MEPO822 will not be there anymore.
Hope this will help you guys if you're having the same problem in future.
Thanks,
Crystal.
