  Cause
  The primary causes of this error message include:

  Inconsistent Data Model: If there are inconsistencies between the data model in the database and the data model defined in the ABAP Dictionary, this error can occur.

  Solution

  Rebuild the Table: If the change was unintentional or if there are inconsistencies, you may need to revert the change or rebuild the table. This can be done using transaction SE14 (Database Utility).
  Transport Consistency: Ensure that all transport requests related to the data dictionary changes have been imported correctly across all systems (development, quality assurance, production).
