  The SAP error message FDT_CHANGE_INFO304 indicates that certain variables have been deleted from a ruleset in the context of the SAP Financial Data Management (FDT) framework. This error typically arises when there are changes made to the ruleset that affect the variables used within it, leading to inconsistencies or issues in the execution of the rules.
  Cause:
  
  Manual Deletion: Variables may have been manually deleted from the ruleset by a user.
  Changes in Data Model: If the underlying data model has changed (e.g., fields or structures have been modified), it can lead to the deletion of variables that are no longer valid.
  Versioning Issues: If you are working with different versions of a ruleset, variables may be present in one version and not in another.

  Solution:
  
  Review Changes: Check the change log or history of the ruleset to identify what changes were made and by whom. This can help pinpoint the cause of the variable deletion.
  Restore Variables: If the deletion was unintentional, you may need to restore the deleted variables. This can be done by either:
  
  Re-adding the variables manually to the ruleset.
  Importing a previous version of the ruleset that contains the required variables.
  
  
  Update References: Ensure that any references to the deleted variables in other parts of the ruleset or related rules are updated or removed to prevent further errors.
  Testing: After making changes, thoroughly test the ruleset to ensure that it functions correctly without the deleted variables.
