• What is the cause and solution for SAP error message SR442 - New serialization supports only destination types 3, I, L, and T ?

  The SAP error message SR442, which states "New serialization supports only destination types 3, I, L, and T," typically occurs in the context of SAP's serialization functionality, particularly when dealing with the serialization of objects or data types in the system.
  Cause:
  This error indicates that the serialization process is attempting to use a destination type that is not supported by the new serialization framework. The supported destination types mentioned in the error message are:
  
  3: This usually refers to a specific type of data or object.
  I: This typically stands for integer types.
  L: This usually refers to long types.
  T: This generally indicates time or timestamp types.
  
  If the serialization process encounters a destination type that is not one of these, it will trigger this error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Data Types: Review the data types being serialized. Ensure that they conform to the supported types (3, I, L, T). If you are using custom types or unsupported types, consider converting them to one of the supported types.
  
  
  Update Serialization Logic: If you are using custom serialization logic, update it to ensure that it only handles the supported destination types. This may involve modifying the code to check the type before attempting serialization.
  
  
  Review Configuration: Check the configuration settings related to serialization in your SAP system. Ensure that they are set up correctly and that there are no misconfigurations that could lead to unsupported types being processed.
  
  
  Consult Documentation: Refer to the SAP documentation for serialization to understand the supported types and any limitations that may apply. This can provide insights into how to structure your data for serialization.
  
  
  Testing: After making changes, thoroughly test the serialization process to ensure that it works as expected without triggering the error.
  
  
  SAP Support: If the issue persists after trying the above solutions, consider reaching out to SAP support for further assistance. They may provide additional insights or patches if this is a known issue.
