• What is the cause and solution for SAP error message WS_TOOL893 - Row type of table &1 has changed ?

  The SAP error message:
  WS_TOOL893: Row type of table &1 has changed
  
  Cause:
  This error occurs when the row type (structure) of an internal table has been changed in the ABAP Dictionary or in the program after the table has already been used or declared. Essentially, the internal table's structure definition has been modified (for example, fields added, removed, or changed), but the runtime environment or the program still expects the old structure.
  Common scenarios include:
  
  Changing the structure of a table type or a data dictionary structure that is used as the row type of an internal table.
  Modifying the structure after the program has been loaded or after the internal table has been declared.
  Inconsistent or outdated generated code or cached metadata in the runtime environment.
  
  
  Solution:
  
  
  Re-activate the program or object:
  
  After changing the structure, re-activate the program or function module that uses the internal table.
  This ensures that the latest structure definition is used.
  
  
  
  Clear the buffer/cache:
  
  Sometimes, the runtime environment caches old structure definitions.
  Use transaction SE38 or SE80 to re-activate the program.
  You can also use transaction SE14 to adjust or activate database objects if related.
  
  
  
  Check the structure consistency:
  
  Verify that the structure used as the row type of the internal table is consistent and active in the ABAP Dictionary (SE11).
  If the structure was changed, ensure all dependent programs are re-activated.
  
  
  
  Restart the SAP application server (if necessary):
  
  In rare cases, the application server cache might hold old metadata.
  A restart can clear this cache.
  
  
  
  Check for runtime type changes:
  
  If dynamic internal tables are used (e.g., created with CREATE DATA or REF TO DATA), ensure the runtime type matches the current structure.
  
  
  
  
  Related Information:
  
  This error is related to the internal table row type consistency between design time and runtime.
  It is often encountered during development or transport of objects where structures have been changed.
  SAP Note references (if available) can be checked via SAP Support Portal for specific system versions.
  Similar errors include WS_TOOL894 which also relates to type changes.
