3523337 - Error - "PEV with expense document reference 'DEF-1' of type Expense Report already exists" occurs while trying to post the Concur Expense Report

When trying to upload an expense report from Concur into SAP Business ByDesign, you can see there are two business transactions for the same expense report.

First expense report was already posted and when you are trying to post the second document, you are facing the error "PEV with expense document reference 'ABC-1' of type Expense Report already exists" 

'ABC' refers to the Expense Report.

SAP Business ByDesign 

1. Go to the General Ledger work center.
2. Go to the Source documents sub view.
3. Filer it with unposted source documents.
4. Search for the relevant expense report 'ABC'.
5. There are two business transactions with the same expense report ID's.
6. The first expense report 'ABC-1' is already in posted status and the second one is in In-process status with the below mentioned error message,

"PEV with expense document reference 'ABC-1' of type Expense Report already exists" 

The first expense report document was posted as there is no other reference source document ID. But the second expense report document with the same source document ID is not getting posted because system will validate if there is any posting for the source document and it will raise error "PEV with expense document reference 'ABC-1' of type Expense Report already exists".

So, explicitly reposting any source document from the UI is not possible.

The reason for the split of expense report with the same ID is, the first expense report is not posted successfully in full.
Both the first and second expense report documents are related to concur expense report and SAP splits here because there is a part relevant as open item for the employee account and a part which is paid by credit card.
Only one part was posted which is the first expense report. And to post the second part (second expense report) you have to create a case to SAP Technical Support, once we validated the second expense report document will be posted from the backend by our development.
