Classification of the mandate based on how the collection amount is determined. In the ZA_AC scheme this is the mandate's Debit Value Type, and it dictates strict interbank validation rules for how collection amounts are calculated, capped, and adjusted over the life of the mandate.
The rules for each value are:
FIXE(Fixed): Used for contracts where an upfront, calculated Instalment Amount is the basis for normal collections. Regular collections are strictly validated and cannot exceed this Instalment Amount. The Adjustment Category (adjustment.category) for a fixed mandate must strictly beNEVR(Never).VARI(Variable): Used for contracts where an upfront Instalment Amount is calculated but can be amended by the Creditor based on pre-agreed variables, such as annual increases or interest rate changes. Regular collections cannot exceed the currently active Instalment Amount.USGB(Usage-based): Used for contracts where the collection amount fluctuates depending on the Payer's usage of a product or service during the payment cycle. Unlike fixed and variable mandates, the regular Instalment Amount (collectionAmount) is optional, and interbank validation is instead performed strictly against a mandatory Maximum Collection Amount (maximumAmount).
