Abstract:

A system and method (10) for deriving access codes for billing customers includes a load process (12) receiving a set of system attributes (20) and using at least one of the system attributes (20) for looking up in at least one lookup table (16, 18, 22, 24) for an access code and at least one formula value, and further storing the access code and at least one formula value in an access code lookup table (26, 28). The system (10) further includes a derivation process (14) which receives a specification of values for the set of system attributes from a billing record (30), uses the specification of values for looking up in the at least one lookup table (16, 18, 22, 24) for a derivation formula, uses the derivation formula for looking up in the billing record (30) for an attribute value, and further uses the attribute value for comparing with the formula value stored in the access code lookup table (26, 28). The access code associated with the formula value comparable to the attribute value is the derived access code.
