• What is the cause and solution for SAP error message FDT_CHANGE_INFO221 - GDT binding was changed from &1 to &2 ?

  The SAP error message FDT_CHANGE_INFO221 indicates that there has been a change in the binding of a Global Data Type (GDT) in the context of the Field Data Tool (FDT). This message typically arises when there is a mismatch or inconsistency in the data type bindings used in your FDT configuration.
  Cause:
  The error occurs when:
  
  A GDT that is being used in a field or structure has been modified, and the binding of that GDT has changed from one type to another (from &1 to &2).
  This can happen due to changes in the underlying data model, such as updates to the GDT definition or changes in the data structure that references it.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check GDT Definition: Review the definition of the GDT that is causing the issue. Ensure that the data type and its properties are correctly defined and that any changes made are intentional.
  
  
  Update Bindings: If the GDT has been changed, you may need to update the bindings in the FDT configuration to reflect the new data type. This may involve:
  
  Modifying the field mappings in the FDT.
  Ensuring that all references to the GDT are consistent throughout your application.
  
  
  
  Consistency Check: Perform a consistency check in the FDT to identify any other potential issues related to data type bindings. This can help you find other areas that may need attention.
  
  
  Transport Requests: If the changes were made in a development environment, ensure that the transport requests are correctly managed and that the changes are moved to the appropriate environments (e.g., QA, Production).
  
  
  Testing: After making the necessary changes, conduct thorough testing to ensure that the application behaves as expected and that there are no further issues related to data type bindings.
  
  
  Related Information:
