Please advise on the filing

Hello Folks,

My friend who working with a  Mumbai based company was moved to Kuwait last year for a temporary project for 2 yrs. He is receiving salary in Kuwaiti Dinar. For FY 19-20 he got a Annexure to From 16 from his Payrol team containing detail of the salary he received in Kuwait converted to Indian rupees. Can you please confirm whether he needs to pay tax for this F.Y ? I couldn't see any details about this Annexure in form 26 AS. 

Thanks
