Handling Multiple Error Messages through EXIT_SAPMM06E_012 for ME28

Question

Dear Team,
                       After Executing ME28, system will give List of PO's that are to be Released . User will select Multiple  PO's and
Press Release button in Application toolbar. once it is relased, User will press save Icon for all released PO's. 
Once Save icon is presed, I need to  do  Validation for Multiple PO's in the user Exit EXIT_SAPMM06E_012 and capture my
ErrorMessages for all Released PO's for which Validation fails.
Here in the given user Exit, one PO will be processed at a time as PO is defined as Import Parameter but it will handle all PO's
and give the output in status bar saying 'Relased Saved' for all PO's which succesfully gonethrough.
once we execute ME28, system is showing list output with PO's to be Released(As system is handling with Write statments). In this case, we dont have scenario of PBO and PAI Modules( where user can correct error if any validation fails) like we have for ME22,etc.
I have Written simpel Error Message in the  User Exit.
once i tried to trigger my user exit  by Releasing and Saving with One PO, Error Message is displayed ( as information Message
appears) and if i Press Exit button in Error Message, it is coming out of Transaction.
Is there any Possibilty to Handle Multiple Error Messages ( in my case for  Valdiation Failed Po's)  in ME28 ,after Releasing and Saving , and also user should not come out of Transaction once  Error Messages are Displayed.
Thanks and Regards
Suresh

Hi Suresh,
there is a tekpo table to handle all po items. you can put it in loop and do validations.
if any errors through, there may be a ex_messages table of type bapiret2.
or
try like this:  MESSAGE E368(00) WITH TEXT-001 TEXT-002.
thanks
