You are trying to set up an offsetting account determination group (ADG) for an expense type, however the system informs that a second ADG is not permitted.
SAP Business ByDesing.
Reproducing the Issue
Go to Business Configuration work center.
Go to Implementation Projects view.
Open activity list.
Open activity Expense Reporting - <country>.
Click Edit expense types.
Highlight the relevant expense type.
Click Account Determination tab
Select a ADG as Offsetting Account for Paid Expenses.
The following error is raised: 'Second acct det. group for expense type <expense> not permitted'
When payment taxation is set as Reimbursement Amount (Payment, No Taxation), there is no need to maintain an offsetting account.
When the mentioned taxation is assigned to an expense type, it means that the expense is paid to the employee via a vendor; i.e. the posting goes from an account (maintained in the expense) to the personal vendor of the employee. Here an offsetting account makes no sense and is therefore not allowed to be entered.
This is the designed system behavior.
