When posting to expenses and payables accounts, the G/L account is always derived from the symbolic account, and, if necessary, from the Employee Grouping for Account Determination.

When posting to customer and vendor accounts, you have two possibilities for controlling account determination:

• If you want to use fixed customer and vendor accounts, you can directly assign the number of the customer or vendor account to a symbolic account and, if necessary, an employee grouping.
• If you want to run customer and vendor accounts on an employee basis, you can set the system in such a way that the personnel numbers are also included in account determination.

You have made the necessary settings in Payroll Customizing, under ® Reporting for Posting Payroll Results to Accounting ® Activities in AC System ® Assign Accounts.
