This blog entry explains how to modify a business rule flow using the Rules Manager (runtime) and NWDS (design time) in combination. It covers the creation of rules within the Rules Manager and their integration into the rule flow from NWDS. Using both, Rules Manager and NWDS, enables an efficient collaboration between the business and technical site of users what is realized by a simple deploy and download procedure.

This example relies on the Credit Card BRM application available as download on the Netweaver BRM Homepage.

 

Example:

A credit card applicant has to be firstly evaluated to meet a decision which card he is permitted to obtain. The credit card selection in this example is restricted to a standard and gold card offering. To enhance the card offerings, rules for a platinum card are going to be integrated into the business rule flow.
