The Intermediary system enablement or disablement message is a multi-functional message designed specifically for insurance intermediary systems administration allowing trading agreements between insurance companies and their agents (intermediaries) for insurer products to be initially authorized and consequently controlled by the insurer. This encompasses the enabling (or disabling) of separately identifiable software driven business functions (new business, mid-term adjustment,renewal etc.) and thus administering the authorization for point of sale usage for the individual components of the function. Associated ranges of numbers for insurer products can be initially allocated and maintained via the use of this message.
