We are trying to use SOAP UI to perform an update request using PSI Resource ASMX Web Services. We are simply performing an update with the same resource dataset information obtained from the ReadResource call.

The exception is generic but does anyone know what can be wrong here? the method called has no documentation (DataSetHasMsxColumns) but the name might be suggestive to someone used to work with the services.
Thank you in advance Best Regards
