How to show this error message

[former_member582701]

Hello,

I need to show an error message when the input parameters of the program are not filled, without to exit of the program.

In other words i need to do the same that if i put this parameter as Obligatory, just that i have to show another message instead of standard "Make an entry in all required files".

Thanks

you can do this...

at selection-screen.

if p_one is initial.
 message e001 with 'enter the value for something'.
endif.

if s_matnr is initial.
 message e002.
endif.

I suggest to use message type 'S' instead of 'E'. This keeps all the selection screen fields open without exiting from selection screen.

at selection-screen.

if p_one is initial.

message S001 with 'enter the value for something'.

EXIT.

endif.

if s_matnr is initial.

message S002.

EXIT.

endif.
