• What is the cause and solution for SAP error message CMT2123 - Structure contains serialized objects and cannot be copied ?

  The SAP error message CMT2123, which states "Structure contains serialized objects and cannot be copied," typically occurs when you are trying to copy a structure that includes serialized objects. Serialized objects are those that have been converted into a format that can be easily stored or transmitted and then reconstructed later. In SAP, this often relates to complex data types or structures that include references to other objects.
  Cause:
  
  Serialized Objects: The structure you are trying to copy contains fields that are serialized, which means they cannot be duplicated directly.
  Data Type Restrictions: Certain data types in ABAP (Advanced Business Application Programming) cannot be copied if they are serialized, as they may contain references to other objects or complex data types.
  Incompatibility: The copying operation may not support the serialization format of the objects within the structure.
  
  Solution:
  
  Avoid Copying Serialized Structures: Instead of copying the entire structure, consider creating a new structure that only includes the necessary fields that are not serialized.
  Use Deep Copy: If you need to copy the structure, consider using a deep copy method that handles serialized objects appropriately. This may involve writing custom logic to handle the serialization and deserialization of the objects.
  Check Data Types: Review the data types within the structure. If possible, replace serialized fields with simpler data types that can be copied.
  Refactor Code: If the structure is part of a larger program or function, consider refactoring the code to avoid the need to copy the structure directly.
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance on handling serialized objects in your version of SAP.
