Using SAP Crystal Reports runtime for .NET Framework 13.0.6.1027.
When we attempt to open a report through the API, we get the following stack trace:
CrystalDecisions.Shared.CrystalReportsException: Load report failed. ---> System.Runtime.InteropServices.COMException:
Invalid field name.
test {F5113347-127C-404A-8BDC-F80657C83034}.rpt
I have removed all the database fields, formulas, etc from the report so that it is just a shell at this point, and we still get this error. This report would load fine using the legacy RDC API, but as soon as we switched to .NET, the "Invalid Field Name" error was thrown.
It is not a security/permissions issue. We are able to open other reports using the .NET interface properly. Certain reports only are causing this error. I attached the report file (please rename to .rpt as the form would not allow me to attach it otherwise).
Any assistance would be greatly appreciated as we have spent a considerable amount of time trying to debug this issue, without success.
