GSTR3B OFFSET ERROR

Mohammed Goryawala (727 Points)

02 November 2017  
I have IGST credit of ₹91811/-
CGST credit of ₹24573/-
SGST credit of ₹24573/-
Cash ledger ₹69391/-

Amount of tax payable is CGST ₹104874/-
AND SGST ₹104874/-.

I AM TRYING TO SETOFF but error shows that 'Cross Utilization is not allowed"
Adn at times it shows that cash/credit balance is insufficient.

What I may be doing wrong in this?
Please help
