  The SAP error message CM_SUB_BAPI001 indicates that you are trying to use long material numbers in a system that is operating in compatibility mode, which does not support long material numbers. This error typically occurs when you are working with BAPIs (Business Application Programming Interfaces) or other functions that involve material master data.
  Cause:
  
  Compatibility Mode: The system is set to compatibility mode, which means it is configured to work with older versions of SAP that do not support long material numbers (more than 18 characters).
  Long Material Number Usage: You are attempting to use a material number that exceeds the 18-character limit allowed in compatibility mode.
  
  Solution:
  
  
  Switch to Extended Material Number: If your business processes require the use of long material numbers, you may need to switch your system out of compatibility mode. This typically involves:
  
  Changing the system settings to allow for extended material numbers.
  Ensuring that all relevant configurations and master data are updated to support the new format.
  
  
  
  Use Short Material Numbers: If switching out of compatibility mode is not feasible, you will need to ensure that all material numbers used in your transactions are 18 characters or fewer. This may involve:
  
  Modifying your data input to use short material numbers.
  Reviewing any integrations or interfaces that may be sending long material numbers to the system.
  
  
  
  Check Configuration: Review the configuration settings in your SAP system to determine if compatibility mode can be disabled. This may require assistance from your SAP Basis or technical team.
  
  
  Related Information:
  
  Material Number Length: In SAP, material numbers can be either short (up to 18 characters) or long (up to 40 characters). The choice between these formats depends on the system configuration and business requirements.

  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or updates related to this error message.
