3788535 - How to bypass error message FF747 when posting supplier invoice with manually input vat amount greater than calculated tax amount via Create Supplier Invoice - Advanced App - SAP S/4HANA Cloud Public Edition

The error message "The tax amount must not be greater than the tax base" (Error ID FF747) occurs when posting a supplier invoice where the import VAT amount exceeds the supposedly calculated tax amount via Create Supplier Invoice - Advanced App. This article provides a guide on how to bypass this error message. 

"Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental." 

SAP S/4HANA Cloud Public Edition

1. Navigate to Create Supplier Invoice - Advanced App and create a supplier invoice.
2. Enter the import VAT amount which is greater than the tax base amount.
3. Simulate/Post the invoice.
4. Observe that error message FF747 - "The tax amount must not be greater than the tax base" occurs.

This is a standard system behavior. Error message FF747 is triggered by a system validation that prevents the tax amount from exceeding the tax base amount.

In case due to business requirements, it is mandatory to post an invoice in which the import VAT amount exceeds the supposedly calculated tax amount, consider modifying Tax Code Properties to bypass the error message FF747. Note that there are some exceptional cases in which the error cannot be bypassed.

The details are as follow:

1. Navigate to configuration activity 101016 – Tax Code Properties.
2. Locate the relevant tax code.
3. Unflag the 'CheckID' indicator in the tax code properties.
4. Additionally, review the 'Tol.per.rate' (Tolerance Percentage) field in the tax code properties — this field authorizes the amount entered in the invoice and controls further calculation tolerance.

This allows a warning to be issued instead of a hard error, or bypasses the check entirely, enabling the invoice to be posted with a tax amount exceeding the calculated tax amount.

***Exceptions***

1. The logic can only be triggered for non-zero tax rate.

2. The logic can only work if the manually input tax amount is not greater than the tax base amount. In case the manually input the tax amount is greater than the tax base amount, the error FF747 will always be raised and cannot be bypassed.
