Creating a Custom Transform

PSP procedures can invoke any custom business service method that you create using Siebel VB or Siebel eScript. Custom business service methods for PSP should follow these guidelines:

• The row set and context are passed as inputs to the custom business service method.
• Wherever possible, parameterize new methods to make them flexible and applicable to multiple situations.
• The method uses standard property set APIs to read and write from the row set.
• The row set must be returned as an explicit output argument of the business service method.
