Hi Naveen,
Thanks for the update.
I checked your requirement for field level calculations. The Surveys can be completed in GUI, Webclient by internal users or using HTML format by external users. If you are using the survey's for internal users who have access to SAP CRM system you can consider writing the code logic in the PBO module. However, for the HTML format the survey will be filled outside the CRM Landscape (probably through some website), the PBO module cannot be used to control the calculations dynamically.
To be consistent and scalable between diferent survey formats, we need to write all the the field level logic (calculations or Validations) in the survey's XSLT files using JAVA Script.
This would ensure that the survey's can run in any formats without any code change.
Hope this helps.
