WHPRCMAN

Overview

WHPRCMAP models the metadata for data mapping processes in the SAS/Warehouse Administrator Process Editor. A data mapping is a metadata record used to generate or retrieve a routine that maps columns from one or more data sources into one or more data tables, detail tables, OLAP tables, or OLAP MDDBs. Common mappings include one-to-one (one data source to a target table), joins (one or more data sources merged by one or more common columns), and unions (two or more data sources appended to a target table). Here is one way to add a data mapping process in SAS/Warehouse Administrator:

In the Explorer, select a detail table or a data table with the right mouse button.
Select Process from the pop-up menu.
In the Process Editor, select the table with the right mouse button.
Select Add Inputs
Enter the mapping information.

Properties

The following table lists all of the properties for WHPRCMAP and indicates how you can use each property with metadata API methods.

In the table, you can specify properties with a Yes in the Indirect Add column when you indirectly add one object through another, as described in the documentation for the _UPDATE_METADATA_ method. Use this approach to add a new dependent object. For details, see Using _UPDATE_METADATA_.

You can pass properties with a Yes in the Update column to the _UPDATE_METADATA_ method, as described in the documentation for this method. Use this method to update properties of an existing object. For details, see Using _UPDATE_METADATA_.

* Req indicates that the property is required; you must provide a value for this property when you use a given method. * Default indicates that the system will provide a default value for that property if you do not provide one. * Auto supplied means that the property is automatically supplied; any value that you specify for such a property is ignored.

Properties with a Yes in the Read Method Expand Parm column are valid with the expand parameter of the _GET_METADATA_ method. This method enables you to get detailed metadata about a property and its associated objects through a single method call.

WHPRCMAP is a dependent type. WHPRCMAP has the same usage information as WHPROCES. See the process model diagram in Relationships Among Metadata Types.
