This document describes an error message of "FS716 'G/L account & in tax code & not found'" that occurs when creating FI documents with a specific tax code after an upgrade. The error is caused by note 1596752 which implemented stricter checks for tax accounts that now must exist in the company code and chart of accounts. The resolution is to either create the missing account via transaction FS011 or use a different account for the automatic posting configured in transactions FBKP or FTXP.
