How to validate input in Modulepool program

Former Member — Tue, 07 Oct 2008 13:17:37 GMT

Hi Dears,

I have screen 200. For one of the input field when it has the value coming by default with 'S' i need to allow only 'F' as input if user wants to change. If input is coming by default with 'F' I need to allow 'S' as input if user wants. How can I control this input in module pool programming.

Thanks,

Your requirement is tricky.

Here I would suggest that you change the field to alist box and dynamically set the list values based on the currrent value.

if the current value is "S" or "F" then the list will have only these 2 values.

if it is something else, you can fill the list with the entire list of possible values.

check this

in screen 200 pai

module check

if default = 'S'

use input value = 'F'

else.

message 'incorrect value '.

endif.

if default = 'F'

else.

message 'incorrect value '.

endif.

endmodule.
