How do you export to Excel?
Do you display results first, then use the option to Export to Excel?
If yes, then the extra column is added by the grid control process that ViewPoint uses when rendering results on a pc desktop.
Try right clicking on the View Object, then use the Save as PC file option, the resulting xlsx or xls file should not have the extra column in position A.
Use the EXECUTE command and save the xlsx or xls file to the IFS or email the document. This output should not contain the extra column.
Finally, consider the ViewPoint Excel Add-in function that is installed with the ViewPoint Custom Install Option. You can easily "pull" results into your workbook, instead of "pushing" them out to create a workbook.
