Hi ,

The field should always be declared as a list box in the screen painter first...and then assign a function code to it since the code is trigerred only when the function code is identified.........

Filling the drop down..

(1) if the domain of the field has fixed values assigned to it and the field direcly refers to domain then the drop down list is automatically populated

(2) if the filed is to be populated with custom values then we use a function module

vrm_set_values

Check the program demo_dynpro_dropdown_listbox in se38 for a complete sap standard demo program and code

Hope it helps

Hi Byju,

Thanks a lot for your prompt reply but am unable to find any options to declare my element as a list box. So how should i go about it. Kindly guide as i'm totally new to dialog programming.

I also have another qstn. I just used text boxes as of now to design my layout. When activated it shows me an error like

Input/output field "RP50M-SPRTX" not defined

What could be the issue and how can i go about in fixing it?

TIA.

Hi,

(a) Once we open the screen painter in the change mode..identify the field that needs to be displayed as a check box...double click on that field..a pop up comes..in that there is a field called "dropdown"(3rd or 4th)..select 'list box' ..then enter some text in "Fctcode" like ZDROP..save and activate..

Check the demo program to populate the field with data

(b) Any field that is used on the screen always needs to be defined in the program ...RP50M-SPRTX

Here structure RP50M is not declared in code and screen cannot map the field on the screen to the program whenever it runs

Use another name with same field structure like

data : wa_rp50m type rp50m in the code and use field wa_rp50m-sprtx in the screen .

and do the code accordingly to pass data to and from the field

Hope it helps

Hi Evryone,

Thanks for your courtesy and concern. I have two issues pending now.

1) I have a drop down for a field in my screen. Its a mandatory field and i have many other mandatory fields also. When i select a value from my drop down(mandatory) it gives me a msg Fill in all reqd fields and accepts the value at second time only.

2) Once my 1st drop down is selected i need my another field's drop down to change accordingly. I.E

If i select india as country in my 1st drop down list, then in my 2nd field i should get all states of india as drop down in the second field's list.

Any pointers wil be of great help.

TIA.

Hi,

check these programs...

demo_dropdown_list_box
demo_dynpro_dropdown_listbox

HI,

try this out.

once you select country, based on country add the values to the dropdown list as you did earlier.

if you maintain the states for respective countries a select query will serve your purpose.

like this.

case country.

when 'INDIA'.

CALL FUNCTION VRM_SET_VALUES

....

when 'US'.

ENDCASE.

hope this will help you.
