HI,

Use explicit F4 help, according to the criteria select the data and call the F4 help for the wanted field, with the data you got.

You can use the below function module to build the dialog box for F4 help on the filed.

--> F4IF_INT_TABLE_VALUE_REQUEST

Hi,

I had the same requirement.You have to create dynamic search help.Refer the sample code below:

wa_dynpread-fieldname = 'ZCAN_HDR-PLANT'.
  APPEND wa_dynpread TO it_dynpread.

  CALL FUNCTION 'DYNP_VALUES_READ'
  EXPORTING
    dyname                               = sy-repid
    dynumb                               = sy-dynnr

            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

  CLEAR wa_dynpread.

  READ TABLE it_dynpread INTO wa_dynpread WITH KEY fieldname = 'ZCAN_HDR-PLANT'.

  IF sy-subrc = 0.

    SELECT hawb_bl_no plant exbond_no doc_type cha_agent
    FROM zcan_cha INTO TABLE it_hawb
