Question

how to pass parameters to a form

Asked by: wasabi3689

I have a form(block) named "Find". It's non-data block. In this form, there is an ID and a "Find" button. When users enter the ID field and press the button, another form/block named"Detail Info" will be popped up.


But, when press the button, I want to pass two parameter values to the detail info form. How to do that.

For example, I put the following code to the when-button-pressed trigger

go_block('detail_info');  or

fnd_function.execute(
              function_name=>'XXXX',
            open_flag=>'Y',
            session_flag=>'Y',
            other_params=> v_params || 'G_QUERY_FIND="TRUE"' );

I want to pass ID field and status field to detail block before it is opened.

How to do that? how to modify my code?

Hi,

Well, in the calling form you create a parameter-list:

DECLARE
  pl_id ParamList;
BEGIN
  pl_id := Get_Parameter_List('tempdata');
  IF NOT Id_Null(pl_id) THEN
    delete_parameter_list(pl_id);
  END IF;
  pl_id := create_parameter_list('tempdata');
  Add_Parameter(pl_id,'number_of_copies',TEXT_PARAMETER,'19');
END;

In the form called you have the possibilty to enter expected parameters
(should be between object-groups and popup-menus in the
tree hierarchy). There you create a parameter (in this example
'number_of_copies'). In this form you can use the data as
:parameter.parametername (in this example :parameter.number_of_copies).

which is calling form? which is form called in your case.  When I press the button, I have the following error

frm-47027:Cannot add parameter 430543G-Query_find to parameter list FND-FORM_ARGS:invalid key specified.

here is my code

declare
      v_params VARCHAR2(300);

      v_download VARCHAR2(300); --NUMBER;
   
   CURSOR c_check_download IS
      select
      xdv.DOWNLOAD_ID
      from apps.XX_LICENSED_PRODUCTS_V xlv, apps.xx_licenses xl, apps.XX_DOWNLOADS_V xdv
      where xl.LICENSE_ID=xlv.LICENSE_ID
      and xlv.DOWNLOAD_ID =xdv.DOWNLOAD_ID
      and xlv.PRODUCT_STATUS='Latest'
      and xl.license_number=:find_downloads.license_number;

begin
           open c_check_download;
           fetch c_check_download into v_params;
           close c_check_download;

      fnd_function.execute(
              function_name=>'URL_DOWNLOADS',
            open_flag=>'Y',
            session_flag=>'Y',
            other_params=> v_params || 'G_QUERY_FIND="TRUE"' );

            
end;

I want to pass download_id to open block XX_downloads_v in Find_downloads block

I think that you have to use MarkusId's solution and not your code. In your case "Find" form is calling form and "Detai Info" is called form.
It can looks something like this:
-- this is WHEN-BUTTON-PRESSED trigger in "Find" form
DECLARE
  pl_id ParamList;
  v_params VARCHAR2(300);
v_download VARCHAR2(300); --NUMBER;
   
   CURSOR c_check_download IS
      select
      xdv.DOWNLOAD_ID
      from apps.XX_LICENSED_PRODUCTS_V xlv, apps.xx_licenses xl, apps.XX_DOWNLOADS_V xdv
      where xl.LICENSE_ID=xlv.LICENSE_ID
      and xlv.DOWNLOAD_ID =xdv.DOWNLOAD_ID
      and xlv.PRODUCT_STATUS='Latest'
      and xl.license_number=:find_downloads.license_number;
BEGIN
open c_check_download;
           fetch c_check_download into v_params;
           close c_check_download;

  pl_id := Get_Parameter_List('tempdata');
  IF NOT Id_Null(pl_id) THEN
    delete_parameter_list(pl_id);
  END IF;
  pl_id := create_parameter_list('tempdata');

  Add_Parameter(pl_id,'function_name',TEXT_PARAMETER,'XXXX');
  Add_Parameter(pl_id,'open_flag',TEXT_PARAMETER,'Y');
  Add_Parameter(pl_id,'session_flag',TEXT_PARAMETER,'Y');
  Add_Parameter(pl_id,'other_params',TEXT_PARAMETER,'v_params||'G_QUERY_FIND="TRUE"');
-- call form "detail info" - detail_info
      call_form('detail_info', no_hide, no_replace, no_query_only, share_library_data,pl_id);
destroy_parameter_list(pl_id);
END;
