  The SAP error message CACSBAS151 indicates that a specific function module, referenced as "&1", for a tool identified as "&2", does not exist or is currently inactive. This error typically arises in the context of SAP's Business Application Programming Interface (BAPI) or when using specific tools or applications that rely on function modules.
  Causes:
  
  
  Non-Existent Function Module: The function module specified in the error message may not exist in the SAP system. This could be due to a typo in the function module name or the function module not being created or transported to the system.
  
  
  Inactive Function Module: The function module exists but is not active. This can happen if the function module was recently created or modified and has not been activated yet.
  
  
  Authorization Issues: The user may not have the necessary authorizations to access the function module, leading to the perception that it does not exist.
  
  
  System Configuration: The tool or application may not be properly configured to use the specified function module, or there may be a mismatch in the version of the tool and the function module.
