The export failed because the active workbook cannot be retrieved.
Explanation
The oleGet method failed to retrieve the active workbook object from Microsoft Excel. Rational DOORS needs the active workbook object in order to be able to export data to and from Excel. This problem often occurs when either Rational DOORS or Excel runs out of memory.
User response
Verify whether Rational DOORS or Microsoft Excel ran out of memory. If either product ran out of memory, restart Rational DOORS, exit Excel, and try to export the module again. Also, make sure that your system is not running out of memory.
