Liquid UI: Call command - capturing RFC exception

(1/1)

rajesh.sabbineni:
If the function call ends with an "exception", no error message is shown to the user. To capture the exception use variable.exception

rfcresult = call("BAPI_USER_GET_DETAIL", {"in.USERNAME":"&V[_user]", "out.LOGONDATA":"z_logondata", "table.PARAMETER":"z_parameters"});

if(rfcresult.exception){
   return('E: '+rfcresult.exception);
}
