What does the following error message mean?

"E The system identifier of the principal output file is unknown null "

How do I fix it?

Thanks!

Hi,

I believe it is an error from the XSLT engine that tries to obtain a location relative to the transformation output location, for instance if you use result-document to write to some file and specify a relative location. The fix is to set an output location in your scenario, in the Output tab fill in the Save As field. The relative location will be resolved relative to that.

If this does not solve your problem or my guess was wrong then please try to post a cut down sample together with a short description to allow us to reproduce the behavior.

Best Regards,
George
