• What is the cause and solution for SAP error message CM_SUB_BAPI003 - In compatibility mode long material numbers cannot be converted ?

  The SAP error message CM_SUB_BAPI003 indicates that there is an issue with the conversion of long material numbers when the system is operating in compatibility mode. This typically occurs when you are trying to use a long material number (more than 18 characters) in a context that does not support it, such as when the system is set to compatibility mode for older versions of SAP.
  Cause:
  
  Compatibility Mode: The system is running in compatibility mode, which does not support long material numbers. This mode is often used for backward compatibility with older systems or processes.
  Material Number Length: The material number being processed exceeds the maximum length allowed in compatibility mode (usually 18 characters).
  Configuration Settings: The settings in the SAP system may not be configured to handle long material numbers properly.
  
  Solution:
  
  Switch Off Compatibility Mode: If possible, switch off compatibility mode in your SAP system. This will allow the system to handle long material numbers correctly. This can usually be done in the system settings or configuration.
  Use Short Material Numbers: If switching off compatibility mode is not an option, consider using short material numbers (18 characters or fewer) for transactions that require compatibility mode.
  Check BAPI Usage: If you are using a BAPI (Business Application Programming Interface), ensure that it is compatible with long material numbers. You may need to use a different BAPI that supports long material numbers.
  Review Custom Code: If there is any custom code or enhancements in your SAP system, review them to ensure they are not forcing the system to operate in compatibility mode unnecessarily.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes or updates that may address this issue. There may be patches or updates that resolve compatibility issues with long material numbers.
