I want to modify my POS sale detail report, as here in saudi arabia the VAT which is currently 5%, will be changing to 15% from july 1st 2020, for that , I need to apply a condition in POS sale detail report that,
if the date range is from January 1 2020 - June 30 2020, the report should calculate the VAT as 5%,
if the date range is July 1 2020 onwards, the report should calculate the VAT as 15%,
kindly tell me how to do the coding from xml view...
