  Causes:
  
  Invalid Structure Definition: The custom structure may not be defined correctly in the Data Dictionary (SE11). This could include missing fields, incorrect data types, or other inconsistencies.
  Data Type Mismatch: If the data being processed does not match the expected data types defined in the custom structure, it can lead to exceptions.
  Runtime Errors: There may be runtime errors in the ABAP code that is trying to use the custom structure, such as accessing fields that do not exist or are not initialized.
