Item not appearing in the worksheet after performing history override.

Hi ,

    I am trying to perform history override to an item prior to its min(sales_date) in the worksheet.

I  uncheck hide empty rows  , and perform history override for an item prior to its min(sales_date)

When i query in sales_data table the min(sales_date ) gets changed and rows are inserted in the sales_data table  accordingly.

After re-running the worksheet, the item disappears in the worksheet.. I am unable to filter that item .......

Please help to resolve this issue.

Regards,
