Screen input not getting cleared

Hi All,

I got a peculiar problem,

In my dialog screen(ztcode), i have make a field input enable based on machine and position(Ztable). Now my problem is, when this field gets input enabled im getting some value with this(some 30.12), i really dont know where it is comming from. Even i have cleared this field before endmodule (last stmt in PBO).

Now this looks strange when i jus change my code to screen-input = 0 without anyother modification, its coming disabled with value cleared (0.000). I need to get the value cleared when the input is on. Kindly let me know how to solve this.

if zmach = 'TCE1' and zpos = '01'.

loop at screen.

if screen-name = 'BASE_QTY'.

screen-input = 1.

endif.

modify screen.

endloop.

endif.

cleart base_qty.

endmodule.

Plz its urgent.

Will reward u definetly .

Regards,

Senthil
