Default merge precedence values
BMC Atrium Discovery uses the default precedence values from BMC Atrium CMDB. You can change the precedence defaults as necessary to meet your requirements using Precedence sets. A Precedence set defines the precedence value for a dataset in a Merge activity. Each source dataset is paired with one, and that Precedence set serves as the default precedence value for all classes and attributes in that dataset. The highest value among all source datasets determines the data that is written to the target dataset.
Within a Precedence Set, you can specify individual Precedences for either a class or an attribute, assigning them a precedence value higher or lower than that of the dataset. This prevents one source dataset from providing all the data in a merge. Class-level Precedences apply to all attributes of the class. When the Merge activity is run, the precedence value specified at the most granular level is used for a given attribute.
