I need to display a error msg on selection screen if no data is found for the inputs on the selection screen.
If i give the error msg in START-OF-SELECTION then after error msg the screen does not remain on the selection screen bt comes back to sap start screen.
N if i display my error msg in AT SELECTION SCREEN event den the msg is called even when the user presses enter on the selection screen.
I need to display error msg n also the selection screen to be displayed bt nt when user presses enter.
Currently im checking sy-ucomm in AT LINE SELECTION and running it only when its ONLI i.e execute.... Kindly suggest some other ways of doing it
