how to validate mandatory fields before execution?

Former Member — Mon, 08 Sep 2008 12:58:23 GMT

Hi Experts,

I have lot of selection screen fields. so i am putting all these into number of tabs.

as per each tab wise i am fetching the data.

all the tabs contain same screen number.

here problem is if i enter one mandatory field in one tab and try to execute. it is not fetching the data nor it is not showing any warning/error msg for values in remaining mandatory fields in other tabs.

can anybody tell me how to solve this.

Thanks in Advance,

venkat

Option 1 : use the keyword 'MANDATORY' in the parameters/select-option declarations

Option 2 : check for field values in 'AT SELECTION-SCREEN' and issue Error messages

You need to use event AT SELECTION-SCREEN ON <> for each select-option.

Suppose you have select-option S_AMTNR, then

AT SELECTION-SCREEN ON S_MATNR.

if s_matnr EQ <>.

message E000.

else.

endif.

This will solve ur problem
