We have a Travel expense system developed using SharePoint 3.0 for submitting and approving travel claims. It's an old system and recently we changed all the user login information.
Old login ID is
New login ID is
The new user information were updated into the SharePoint user profile. After the change, users are able to submit claims however when the claim is routed to any approver, he is not able to approve with below errors:
5/12/2016 4:13:03 PM | Infopath FormEvents_OnSubmitRequest: InfoPath cannot submit the form. An error occurred while the form was being submitted. The form cannot be submitted to the following location: http://officeapps.domain.com/TnE/Expense Claim/166509-0000014.xml The file "Expense Claim/166509-0000014.xml" is checked out or locked for editing by domain\d773106. 5/12/2016 4:13:04 PM | Infopath FormEvents_OnSubmitRequest Stacktrace: at Microsoft.Office.Interop.InfoPath.SemiTrust.DAVAdapter.Submit() at Microsoft.Office.Interop.InfoPath.SemiTrust.DAVAdapterObjectWrapper.Submit() at ExpenseForm.FormCode._ProcessReviewViewLogic() at ExpenseForm.FormCode.FormEvents_OnSubmitRequest(DocReturnEvent e)
domain\d773106 is the approver who is trying to approve the claim. It seems the claim is locked by the approver himself.
Any idea what is causing the issue?
