CDW precedence rules determine what published data is included in the CDW domain when differing data has been published from multiple authoring tools. For each CDW schema object, class definitions, interface definitions, property definitions, and relationship definitions, you can specify which domain's data should be given priority over the data from other domains.
When you create a precedence rule, you provide a name for the rule and a list of the domains from which the data should be given priority and the order in which they should be considered, using an Order Value.
While data from each domain is stored safely in the database, regardless of these precedence rules, these rules will determine what data is stored in the CDW domain. Data from a domain with a lower Order Value will not override the data in the CDW domain, even if it was published after the older data from the domain with a higher Order Value.
For example, a rule might include the following:
|
Domain |
Order value |
|---|---|
|
ELE |
100 |
|
PID |
90 |
|
SP3D |
90 |
|
LLA |
80 |
In this example:
-
Data the LLA domain is prioritized over data from domains not listed.
-
Data from the SP3D or SPPID domain is prioritized over data from LLA.
-
Data from ELE domain is given the top priority and will not be replaced in the CDW domain with data from any other domain.
-
Since the PID and SP3D domains have the same Order Value, they are both considered a higher priority than the LLA domain and a lower priority than the ELE domain, but neither is a higher priority than the other. If data from either of these domains is stored in the CDW domain when the different data is published into the other domain, the CDW domain value will be replaced with the new value.
