  The SAP error message CRD_MDA404 indicates that there is a missing authorization for Remote Function Call (RFC) in the specified module. This typically occurs when a user attempts to execute a function or transaction that requires specific authorizations that they do not possess.
  Cause:
  
  Missing Authorization Object: The user does not have the necessary authorization object assigned to their user profile for the specified module.
  Role Assignment: The user may not have the appropriate roles assigned that include the required authorizations for the RFC.
  Profile Issues: The user profile may not be correctly configured to allow access to the required functions.
  Transport Layer Restrictions: If the RFC is related to a transport layer, there may be restrictions based on the transport settings.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to see which authorization check failed. This will provide insight into what specific authorization is missing.
  Alternatively, you can use transaction SU01 to check the user’s authorizations directly.
  
  
  
  Review Roles and Profiles:

  Add Missing Authorizations:
  
  If you identify the missing authorization object, you can add it to the user’s role or profile. This may require the assistance of a security administrator or someone with the appropriate permissions.
  
  
  
  Testing:
  
  After making changes, have the user log out and log back in to ensure that the new authorizations take effect.
  Test the functionality again to confirm that the error has been resolved.
