• What is the cause and solution for SAP error message FDT_CHANGE_INFO399 - Function assignment of the ruleset was changed ?

  The SAP error message FDT_CHANGE_INFO399 indicates that there has been a change in the function assignment of a ruleset in the context of the SAP Fiori Design Time (FDT) framework. This typically occurs when a ruleset that is being used in a particular context has been modified, which can lead to inconsistencies or issues in the application that relies on that ruleset.
  Cause:
  
  Modification of Ruleset: The ruleset associated with a particular function or application has been altered. This could involve changes to the logic, conditions, or the functions that are being called.
  Versioning Issues: If multiple versions of a ruleset exist, the application may be referencing an outdated version that has since been modified or deleted.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), and the transport did not include all necessary components, this error may arise.
  
  Solution:
  
  Check Ruleset Configuration: Review the ruleset configuration to ensure that it is correctly set up and that the function assignments are as expected. You may need to revert to a previous version if the changes are not acceptable.
  Reassign Functions: If the function assignment has changed, you may need to reassign the correct functions to the ruleset. This can be done through the FDT configuration interface.
  Clear Cache: Sometimes, clearing the cache can resolve inconsistencies. You can do this by using transaction codes like /n/iwfnd/cache or /n/sap/bc/ui5_ui5/sap/ars/ to clear the UI5 cache.
  Check Transport Requests: Ensure that all necessary transport requests have been correctly imported into the target system. If there are missing components, you may need to re-transport them.
  Consult Documentation: Review SAP documentation or notes related to FDT and rulesets for any specific guidance or known issues that may relate to your situation.
