This can happen during a transport of changes or when a table is modified in a way that affects its fields, such as adding, deleting, or changing the data type of a field.
  Cause:
  
  
  Table Structure Change: The error is triggered when there is a mismatch between the expected structure of a table and its actual structure in the database. This can happen if:
  
  A field was added or removed.
  The data type of a field was changed.
  The length of a field was modified.
