A/P Importing Error - G/L account cannot be blank

I am trying to import an A/P batch into Sage, I'm using the template downloaded from an already existing batch. The issue is when I select the file (Excel 200 format) and click OK an error window pops up with the G/L account cannot be blank message. 

Am I missing a column that should be in my template? I can't find any G/L account filed to be entered. 

The error message is:

G/L account cannot be blank

Stopped processing at record 0 in Invoices

Thank you!
