In Baan IV, the order balance amount always includes the tax amount. Consequently, the tax amount must be recalculated every time an order line is modified in order to update the balance correctly. If the tax provider is activated, this requires an API call for every re-calculation of tax.
In Infor LN, users can select or clear the new Include Tax in Order Balance check box in the COM Parameters (tccom0000s000) session to indicate whether users want to include tax amounts in the order balance amount. This parameter has an effect on various sessions in Order Management.
