• What is the cause and solution for SAP error message FDT_CHANGE_INFO312 - Structure of the table was changed from &1 to &2 ?

  The SAP error message FDT_CHANGE_INFO312 indicates that the structure of a table has changed, specifically from one version (denoted as &1) to another (denoted as &2). This typically occurs in the context of data modeling or when working with Field Data Management (FDT) in SAP.
  Cause:
  
  
  Table Structure Change: The underlying database table structure has been modified. This could be due to:
  
  Addition or removal of fields.
  Changes in data types of existing fields.
  Changes in the length of fields.
  Changes in the key fields of the table.
  
  
  
  Version Mismatch: The application or the data model you are working with is expecting a different version of the table structure than what is currently defined in the database.
  
  
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), there might be inconsistencies between the systems.
  
  
  Solution:
  
  
  Check Table Structure: Verify the current structure of the table in the database using transaction SE11 (Data Dictionary). Compare it with the expected structure to identify discrepancies.
  
  
  Update Data Model: If you are using a data model that relies on the table structure, ensure that it is updated to reflect the new structure. This may involve:
  
  Modifying the data model to accommodate new fields or changes.
  Re-generating any related objects that depend on the table structure.
  
  
  
  Transport Consistency: If the issue arose after a transport, ensure that all relevant transports have been applied correctly and that the target system is in sync with the source system.
  
  
  Re-activate Objects: If the table structure has changed, you may need to re-activate any related objects (like views, data elements, domains) that depend on the table.
  
  
  Consult Documentation: Review any release notes or documentation related to the changes made to the table structure to understand the implications.
  
  
  Testing: After making the necessary adjustments, conduct thorough testing to ensure that the application behaves as expected with the new table structure.
  
  
  Related Information:
  
  Transaction Codes: Use SE11 for Data Dictionary, SE80 for Object Navigator, and SE37 for Function Modules to investigate further.
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific table or functionality you are working with.
  Field Data Management (FDT): If you are using FDT, ensure that your FDT configurations are aligned with the new table structure.
