Error while doing commint from RFC Adapter

Question

Hi,
We have a SOAP-PI-RFC synchronous scenario. Through this Soap request comes to PI and passed on to BAPI via RFC adapter. This BAPI saves the transaction & return the document number. We are using " PI PI parameter u201CCommit Handling for single BAPI' in RFC receiver Channel.
While this setup works for 1 posting, when we do the mass load ( Say 20 Documents) half of the documents are not able to Save. Although BAPI, returns the document number but on checking the document does not exists in SAP. To do further test, we created a program in ECC and try calling BAPI in loop and calling BAPI Commit.
This way program works fine and there is no error
So in nutshell, when we PI do the commit, half of the documents are not saving where as when the ABAP program commits no error. Is there any  special way that PI calls this commit work.
PS: We created a wrapper BAPI which calls the orgirnal BAPI and Commit BAPI & called this from PI but still the same problem is coming.
Appreciate help on this.
Regards,
Harish

Answer 1

Are there any error messages in the RFC Reciever channel in Runtime Workbench?
RWB -> Component monitoing -> Adapter Engine -> Comm Channel -> filter for type RFC
Please try to give some more details on why the system says the messages are failing.
