“WHSASSTR” on page 231
Overview
WHDYNSAS models the metadata for dynamically generated SAS physical stores in SAS/Warehouse Administrator The WHDYNSAS type is a placeholder for tables that
do not currently support the definition of both physical information and ACCESS information—tables that do not have a Physical Storage tab in their property windows
Properties
WHDYNSAS has the same properties as its parent, “WHSASSTR” on page 231
However, unlike WHSASSTR properties, WHDYNSAS properties cannot be written through the metadata API They can only be read

Overview
WHDYNSRC models the metadata for dynamically generated source code catalog entries in SAS/Warehouse Administrator These entries are generated when you select the
or
Step option for a table in the Process Editor
Properties
The following table lists all of the properties for WHDYNSRC and indicates how you can use each property with metadata API methods
In the table, you can pass properties with a Yes in the Add column to the
_ADD_METADATA_ method Use this method to add a new object
You can pass properties with a Yes in the Update column to the
_UPDATE_METADATA_ method Use this method to update properties of an existing object
* 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
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
Expand Parm.

WHEFILE
Metadata type for external file inputs to ODDs Category: Object Types—Process Editor
Parent
“WHROOT” on page 226
Overview
WHEFILE models the metadata for external file objects in the Process Editor An
external file is a file of type other than SAS that is an input to an operational data
definition (ODD) Here is one way to add an external file in SAS/Warehouse Administrator:
1 In the Explorer, select an ODD with the right mouse button
2 Select Process from the pop-up menu.
3 In the Process Editor, select the ODD with the right mouse button
4 Select Add External File from the pop-up menu
5 Select the external file with the right mouse button
Trang 46 Select Properties.
7 Enter the external file information

New properties for WHEFILE are as follows:
ACCESS METHOD
indicates the SAS filename access method specification
CREATING JOB
specifies a list of general identifying information about the job that creates this file This list must be a WHJOB or a subtype of WHJOB A valid CREATING JOB property is required before you can add any INPUT SOURCES If the CREATING JOB is removed, then any work tables in the chain of INPUT SOURCES will be deleted as well
FILEREF
represents the fileref that is used to access this file using a SAS filename
statement The maximum length is 8 characters
HOST
specifies an SCL List of general identifying information about the host on which this file is accessed
ICON
indicates the catalog entry name of the associated icon For more information about icons, see “Using Icon Information” on page 69
INPUT OBJECTS
specifies an SCL list of general identifying information about the objects that are input to this external file For more details about input objects, see “INPUT and OUTPUT Properties” on page 64
INPUT SOURCES
specifies an SCL list of general, identifying information about the sources that are input to this file For more details about input sources, see “INPUT and OUTPUT Properties” on page 64
OPTIONS

OUTPUT OBJECTS
specifies an SCL list of general identifying information about the objects that are output from this external file For more details about output objects, see “INPUT and OUTPUT Properties” on page 64
