Hi Sunitha,

Try the following.

Say, the field is s_matnr.

for checking the initial condition.

At Selection-Screen on s_matnr.

if s_matnr[] is initial.

message 'Enter the required fields' type E.

endif.

for alpha numeric characters.

At selection-screen on s_matnr.

if not s_matnr[] in sy-abcde.

message 'Enter only characters' type E.

endif.

Hope this helps you.

Hi,

Please refer the code below:

"TO check the values in the selection Screen.

parameter : sp_bukrs like bsis-bukrs.

at selection-screen.

if sp_bukrs is initial.
message ' Input value in the Company Code field' type 'E'.
endif.

"Similar u can use of Relational operators to check for alpah numeric characters.

Thanks,

Hi Sunita,

You can use the piece of code....

SELECTION-SCREEN: BEGIN OF BLOCK c1 WITH FRAME TITLE text-001.

PARAMETERS:p_prog(30) TYPE c.

SELECTION-SCREEN: END OF BLOCK c1.

AT SELECTION-SCREEN ON p_prog.

IF p_prog IS INITIAL.

MESSAGE 'Enter Program name' TYPE 'E'.

ELSEIF NOT p_prog ca sy-abcde.

MESSAGE 'Please enter charecters' TYPE 'E'.

ENDIF.

for the first 'IF' it checks whether the value enter or not.

for the second 'IF' it checks whether the entered values are alphanumeric or not. 'ca' indicates 'Contains Any'.Use 'ca'.
