  The SAP error message /ISDFPS/ME_CA_LUA016 indicates that there is an issue with the parameters being passed to the GetLIST function in the context of the SAP system, specifically related to the Mobile Enablement framework. The message states that two parameters are required: MEUSER and DeviceId, but they are not being provided correctly.
  Cause:
  
  Missing Parameters: The error typically occurs when the function GetLIST is called without the necessary parameters. In this case, it expects a user identifier (MEUSER) and a device identifier (DeviceId).
  Incorrect Configuration: There may be a configuration issue in the mobile application or the backend system that is preventing the parameters from being passed correctly.

  Check Parameter Passing: Ensure that the code or configuration that calls the GetLIST function is correctly passing both the MEUSER and DeviceId parameters. This may involve reviewing the mobile application code or the backend service configuration.
