Specifically, it states that the element type has been changed from one type (denoted as &1, which represents the active version) to another type (denoted as &2). This typically occurs in the context of SAP Forms and Data Transfer (FDT) where data structures are defined.
  Cause:
  
  Data Model Changes: The error usually arises when there are changes made to the data model or the structure of the form that are not compatible with the existing definitions. For example, if a field was originally defined as a string and is now defined as an integer, this inconsistency can trigger the error.

  Solution:
  
  Review Changes: Check the recent changes made to the data model or form. Identify what changes were made to the element types and ensure that they are consistent across all versions.

  Recreate or Adjust the Form: If necessary, recreate the form or adjust the data model to ensure that the element types are consistent. This may involve modifying the data type in the form or adjusting the data model to match the expected types.
  Test the Changes: After making the necessary adjustments, test the form or data model to ensure that the error no longer occurs and that the data is processed correctly.
