• What is the cause and solution for SAP error message FDT_CHANGE_INFO412 - Node type of the node &1 was changed from &2 to &3 ?

  The SAP error message FDT_CHANGE_INFO412 indicates that there has been a change in the node type of a specific node in a data model or structure. The message specifies that the node identified by &1 has changed its type from &2 to &3. This typically occurs in the context of SAP's Flexible Data Model (FDT) or similar frameworks where data structures are defined and manipulated.
  Cause:
  
  Model Changes: The error usually arises when there are changes made to the data model, such as modifying the structure of a node or changing its type (e.g., from a simple type to a complex type).
  Inconsistent Data: If there are inconsistencies in the data definitions or if the data model is not aligned with the underlying data structure, this error can occur.
  Versioning Issues: If different versions of the data model are being used or if there are discrepancies between the development and production environments, this can lead to such errors.
  
  Solution:
  
  Review Changes: Check the recent changes made to the data model. Identify if any modifications were made to the node in question and ensure that they are intentional and correct.
  Consistency Check: Perform a consistency check on the data model to ensure that all nodes and their types are correctly defined and aligned with the expected structure.
  Revert Changes: If the change was unintentional, consider reverting to the previous version of the node type or restoring the original data model.
  Update References: If the node type has been changed intentionally, ensure that all references to this node in the application or data processing logic are updated accordingly to reflect the new type.
  Testing: After making changes, conduct thorough testing to ensure that the application behaves as expected and that there are no further issues related to the data model.
