Payment condition code. This code defines the payment code and the distribution rules of the various pre-payments and open items. It is initialized by the bill-to BP and is controlled in the payment condition table. It is possible to simulate a distribution thanks to the "Simul" button. When creating the order, the corresponding prepayments are automatically created. The payment condition code can be modified as long as no pre-payment has been made and the order has not been invoiced. Such a modification would then trigger the deletion of the already existing pre-payments followed by the creation of the pre-payments related to the new payment condition.
