hi Sneha,

in SE11 you have to maintain the search help for the field you created. Then it will appear automatically, if you place this field as parameter (or select option) on a selection screen.

PARAMETER : p_zid TYPE ztable-zid.

if it does not work you can add:

PARAMETER : p_zid TYPE ztable-zid MATCHCODE OBJECT name_of_the_search_help.

hope this helps

Hi ,

Try this..

Eg:

PARAMETERS Matnr TYPE mara-matnr MATCHCODE OBJECT Mat1.

Here, Mat1 is the search help for Matnr which Has defined as the Search help.

Try this code...


TABLES : ztab.

TYPES: BEGIN OF itab,
zid TYPE ztab-zid,
END OF itab.

DATA: itab TYPE STANDARD TABLE OF itab WITH HEADER LINE.
PARAMETERS: p_zid TYPE ztab-zid.


AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_zid.
  SELECT zid FROM ztab INTO TABLE itab.
  SORT itab.
  DELETE ADJACENT DUPLICATES FROM itab.

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      retfield    = 'ZID'
      dynpprog    = sy-repid
      dynpnr      = sy-dynnr
      dynprofield = 'P_ZID'
      value_org   = 'S'

What you asked for, may look like

1-Create the search help

Give the field zid as import/export parameter

Add a text field not as parameter but as a displayed field

2-In the PARAMETERS instruction use the clause MATCHCODE OBJECT

Other ways to perform it

- In your Z-table define zid as a foreign key on himself

- In the domain definition of zid give the ztable as a table of value

- Create the search help and add it to data-element definition

- Use function modules like F4IF_INT_TABLE_VALUE_REQUEST in an AT SELECTION-SCREEN ON VALUE REQUEST event.

1. input and output..set both to ZID

2. other way is to use F4_INT_VALUE_REQUEST

in this u need to pass an internal table with one column

populate the internal table wirth the zid from ur database table..

hope dis will clear ur doubt...

Hi Sneha,

1. Import Perameter : This flag is used to Read the Values from table

Export Parameter : This Flag is used to get the value in your field

when you double click the value

in Posible values (f4).

2. Lpos,Fpos : One is Line Position and another is Field Position.

Ex: If you want to display carrid , connid in your f4 button

if Lpos Fpos

Carrid 1 2

Connid 2 1

In Selection Screen Carrid -

Connid -

In F4 Selection Connid | connid

| -

Plz Reward if help,

Mahi.
