Logon failed. Unable To Export Report.

Question

Hi,
I am running visual studio 2010 ultimate edition with crystal reports for visual studio v 13.0.1.
I get the following exception when trying to export to PDF where my report has a sub report.
Logon failed.
Failed to export the report.
Error in File temp_04e1d62e-3f2c-4c44-a654-8aaa19d59ac4 {C0ABAF4C-E8A7-4633-A58F-DFAC3443AC58}.rpt:
Unable to connect: incorrect log on parameters.
Both the reports are bound to an .xsd file that in turn is hooked up to a stored procedure at design time (returned as a datatable object) which sets the appropriate datasource on the report object.
If I run each report seperately and export then I can successfully see the data inside the generated PDF document. However as soon as I add a sub report and try and export, bang I get this error.
I have been through your checklist and can confirm that your suggested settings do fit i.e Save data in report = false, case sensitivity on the db etc (this is proved by each report working when run seperately).
Any suggestions/solutions greatly appreciated
Thanks

Answer 1

yes saving it out seperately works and connectivity appears the same also?
