Strategies and Guidelines for Assigning Priorities
In manual mapping, you manually assign CHPIDs to PCHIDs. By contrast, automatic mapping allows the CHPID Mapping Tool to map CHPIDs to PCHIDs, and the tool tries to find the optimal mapping for each CHPID. A key step before performing automatic mapping is assigning priorities. One reason for assigning CU priorities is that your project has two (or more) control units that need to be processed at the same time.
The task of setting CU priorities consists of assigning priority numbers to control units. Setting CU priorities Priority numbers represent the order in which the tool maps the control units. This order is a key requirement of mapping for high availability.
The relationship between priority numbers and their priority (mapping order) is: The lower the priority number, the higher the priority. For example, a control unit with a priority number of 0001 is mapped before one with a priority number of 1000. The priority numbers correspond to the order of processing. A lower priority number indicates a higher level of importance.
This section provides strategies and guidelines to help you assign priority numbers effectively for effective automatic mapping.
