Error: Invalid DSQ <Source Qualifier name> of type <DSQINSTTYPE> for the extension in session transformation instance <SESSTRANSFORMATIONINST name>.
In the XML file, you specified a DSQINSTNAME and DSQINSTTYPE attribute in a SESSIONEXTENSION element that references a non-existent SESSTRANSFORMATIONINST element or a SESSTRANSFORMATIONINST element that does not match the name and type specified in the SESSIONEXTENSION element.
Edit the XML file, and verify the DSQINSTNAME and DSQINSTTYPE attributes match the SESSTRANSFORMATIONINST element name and type. Or, export the object again and then import it.
