double click to forward output to transaction

Question

I have made a program which outputs a list of equipment numbers using WRITE. The transaction IE03 lets the user input an equipment number, execute, and then displays a whole bunch of information on that piece of equipment.

What I would like to do is be able to double click on one of the numbers my program outputs, and then have the data display that IE03 would offer.

How do I integrate my custom program with the standard display functions?

Answer 1

Use the advice which gave vwegert, or:

REPORT  ztest.

CONSTANTS:
  gc_equpment_view_tcode TYPE sytcode VALUE 'IE03'.

DATA:
      gt_eqkt TYPE TABLE OF eqkt,
      gs_eqkt TYPE eqkt.

START-OF-SELECTION.
  SELECT * INTO CORRESPONDING FIELDS OF TABLE gt_eqkt FROM eqkt
  JOIN equi ON ( equi~equnr EQ eqkt~equnr ) UP TO 10 ROWS
  WHERE eqkt~spras EQ sy-langu.

END-OF-SELECTION.
  LOOP AT gt_eqkt INTO gs_eqkt.
    WRITE: / gs_eqkt-equnr, gs_eqkt-eqktx.
    HIDE: gs_eqkt-equnr.
  ENDLOOP.


AT LINE-SELECTION. 
  CALL FUNCTION 'AUTHORITY_CHECK_TCODE' " check S_TCODE auth. object
    EXPORTING
      tcode  = gc_equpment_view_tcode
    EXCEPTIONS
      ok     = 1
      not_ok = 2
      OTHERS = 3.
  IF sy-subrc EQ 1.
    SET PARAMETER ID 'EQN' FIELD gs_eqkt-equnr.
    "check I_TCODE auth. object (see IE03 definition)
    CALL TRANSACTION gc_equpment_view_tcode AND SKIP FIRST SCREEN.
  ENDIF.

Answer 2

First of all, don't use WRITE to create lists - this is stone-age technology. Store your data in an internal table based on a dictionary structure, then use the SALV library to create a list. Take a look at the sample program SALV_DEMO_TABLE_EVENTS to see how to display a list and react to a double click. Note that you can throw away much of the demo program because it shows quite a lot of different functions.

Then, you don't "forward" anything to a transaction. You can call a transaction using the ABAP statement CALL TRANSACTION (which should be obvious), and you can even pass some values using a crooked mix of SPA/GPA parameters and the addition ... AND SKIP FIRST SCREEN. Be aware that this only works for certain kinds of transactions and only if they were programmed to do so. For this, you need to store the equipment number in a global variable using

SET PARAMETER ID 'EQN' FIELD l_my_equipment_number.

and then call the transaction

CALL TRANSACTION 'IE03' AND SKIP FIRST SCREEN.

Be aware that this statement does not perform the default authorization checks - if you need to do so, use the function module AUTHORITY_CHECK_TCODE as specified by the keyword documentation.
