Automatic sorting in BI4.0 webi

Hi,

In Some of my Reports in WEBI4.0 SP6 Automatic sorting is not working and some of the reports we are getting

By Default object(PO Number) Should display Ascending Order But we're not getting this by Default.

On top of BICS connection we're doing these reports

Kindly help me in this Regard.

Thanks in advance.

Thanks & Regards,
