Missing data G/L account

While processing Individual PO i get this error log when I create Sales order. It doesn't allow me to save the Sales Order since G/L account is not determined. Please suggest what FI settings need to maintained to eliminate this error.

I tried VKOA settings with V - KOFI - INT - SORG - 01 - 03 - ERL - 8000000 (G/L A/C)

Still the issue is not resolved
