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 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.
