Screen field values gets vanished

Former Member — Wed, 23 Jan 2008 19:16:39 GMT

Hi,

I`m in the process of creating custom info types and I have a NUMC field on my screen. When I enter a 0 in that field in create or change mode and press "Enter", I find the 0 gets vanished. While in display mode of the same screen, I get the values on the screen field.

The value is getting updated at the backend, whereas does not show up on the screen.

Can any one let me know if I`ve got to handle some logic in PBO event to show '0' on the screen or is this the normal behaviour with the NUMC fields.

This does not happen if I enter anything other than 0.

Regards,

Farhana.

if field data type is NUMC then screen will have space if you enter 0 in edit mode ,if it is dipaly mode then it will display

you can change into charcter data type if you need.

Hello Farhana,

I have written two programs

first program ( Numeric)

data v_num(2) type n.

parameters p_num like v_num.

parameters p_edit as checkbox default 'X'.

at selection-screen output.

if p_edit ne 'X'.

loop at screen.

if screen-name = 'P_NUM'.

screen-input = '0'.

modify screen.

endif.

endloop.

endif.

initialization.

p_num = '00'.

if p_edit = 'X' then when you enter 00 then 00 will be disapper because this is numc field,if you go display mod p_edit ne 'X'

then 0 will be appear.

the same thing you could do using charcter field

Second program ( Charcter)

data v_num(2) type c.

parameters p_num like v_num.

parameters p_edit as checkbox default 'X'.

at selection-screen output.

if p_edit ne 'X'.

loop at screen.

if screen-name = 'P_NUM'.

screen-input = '0'.

modify screen.

endif.

endloop.

endif.

initialization.

p_num = '00'.

Hope you got it.

Thanks

Seshu

Hi Farhana,

By default numc shows 0 in the display mode.
