I have my QTP Scripts in Test Scripts Tab and datasheets (Test Data in Excel workbook for my Oracle application) in the Attachment Tab of TestPlan of QC.
I import these datasheets to Datatable (Global) of QTP and use the data in my application using the QTP Script Parameterization and then Script updates this Global Datatable with auto generated values from application.

Now, the issue is when I export the Global Datatable using Export / ExportSheet function back to the Test Data sheets in attachments tab of QC, I don't find the them being updated.

How can I achieve this export of Global Datatable form QTP to Quality Center Test Plan Tab?
