First, in the Purchases & Payables Setup, the app must be activated via the Amount Check Setup action using the Enable Amount Check field.
In addition, a rounding difference for the amount check can be specified here in the Rounding difference amount check field.
Functionality
After a purchase document has been created, the Check Amount can be defined in the Purchase Statistics page.
If the lines are created later and the document is posted, a check is called that compares the total amount of the lines with the check amount. If these amounts do not match, an error message is displayed.
