Overview

WHLDRDAT models the metadata for data table load processes in the SAS/Warehouse Administrator Process Editor. Here is one way to add a data table load process in SAS/Warehouse Administrator:

In the Explorer, select 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 Edit Load Step.
Enter the process information.

Properties

The following table lists all of the properties for WHLDRDAT 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.

Property Dependencies

When you add or update the LOAD OPTIONS property, if the value of the LOAD TIME COLUMN item is YES, then a valid load time column must exist for the table that is associated with this load process to avoid errors when processing the SOURCE CODE and/or STEP SOURCE CODE properties. You can add a load time column to a table as described in the documentation for the WHCOLTIM type.
