We are getting an error 'No User Mapping for SAP system user XXXX' when delivering reports or user subscription for WF. I came across a [thread|Problem executing reports; where the solution given was to create a user mapping using the BAdI 'Simple bulk user mapping' in SIMGH. However we have diffrent user name schemes in SharePoint and SAP and hence we have used "SharePoint Integration bulk user mapping' from a CSV file. The user mapping entries can also be seen in the view VUSREXTID. Inspite of this we are getting the above error when SCL is trying to deliver reports or when we try to authorize uses from SharePoint for Workflows.
Please suggest a solution.
