Writing SAS Programs for XMLA Web Services
To use the Web service to call your SAS code, you must configure your SAS code as a
stored process. A stored process is a SAS program that is stored on a server and can be
executed by requesting applications. Any stored process can be deployed as a generated
Web service. However, stored processes that are used with XMLA Web services need to
conform to rules that enable the Web service to receive data from the client and return
data to the client.
You can author a stored process manually by using SAS or a text editor to write the code
and then registering the program through SAS Management Console. Alternatively, you
can use a program such as SAS Enterprise Guide or another SAS code generator to
author a stored process using the point-and-click method. Use the following
modifications to make a stored process that can be used with SAS BI Web Services.
Keep in mind that XMLA Web services can return XML data only; no attachments can
be returned.
Note: XMLA Web services in SAS 9.3 will work only with SAS 9.3 stored process
metadata and SAS 9.3 Stored Process Servers.
