How to create a link to another transaction on a record in ALV report.

Question

Hi All,
I have an ALV report output ,if i click on any record in the report i want it to show me the details of the record which is another transaction code in my case.So basically i want to execute that T-code on clicking on the record of the ALV report.
How can i achieve this ,please provide me the insight with same helpful examples.
Thanks in advance,
Swati

Hi,
This solution is for the ALV by Function Module Appraoch.
You need to use the Importing Parameter I_CALLBACK_USER_COMMAND, of the FM Reuse_ALV_GRID_DISPLAY(or LIST Display) for this.
Slis_ev_user_command TYPE slis_formname VALUE 'USER_COMMAND'.
As this is a frequently-used Callback event, the form routine can also be passed directly in the interface by passing the user command in the IMPORTING parameter I_CALLBACK_USER_COMMAND.
This is an exit subroutine and takes care of the Interactive aspect of the ALV. When User performs any action in the displayed ALV, Control automatically goes to this Subroutine.
The interface of the form routine specified must be defined as follows:
             FORM user_command  USING r_ucomm LIKE sy-ucomm
                                      rs_selfield TYPE slis_selfield.
     Parameter R_UCOMM contains the function code triggered.
     Structure RS_SELFIELD contains the following information:
o     tabname  :      Name of the internal output table
o     tabindex :       Index of the internal output table
o     fieldname:      Field name
o     endsum   :     Cursor is located on the totals line
o     sumindex :     If >0, the cursor is located on a subtotals line
o     value    :        Value of the field on the list
o     refresh  :       (Exporting) List should be set up again
o     col_stable:   (Exporting) Keep column position when list is set up    again
o     row_stable:   (Exporting) Keep row position when list is set up again
o     exit      :        (Exporting) Exit list (and ALV)
o              before_action: Call before standard action execution
o              after_action : Call after standard action execution, before list    setup
o              ignore_multi : Internal use
o              sel_tab_field: Internal use
The EXIT routine is called whenever a function unknown to the ALV is   triggered or if the routine call before/after the execution of a  standard function code has been defined by interface parameter.
Ok code for double click is &IC1 for ALV report.
Eg:
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
     EXPORTING
Name of the program
    I_CALLBACK_PROGRAM                    = V_REPID
title
    I_GRID_TITLE                          = 'Details of Storing'
calls subroutine : PF_STATUS_SET
       i_callback_pf_status_set           = 'PF_STATUS_SET'
Calls subroutine : user_command
        i_callback_user_command           = 'USER_COMMAND'
Overall structure of the report
       IS_LAYOUT                          = STRUCT_LAYOUT
Passes the field catg internal table
       IT_FIELDCAT                        = I_FIELDCAT
Passws the sort sequence internal table
       IT_SORT                            = IT_SORT
       I_DEFAULT                          = 'X'
       I_SAVE                             = 'A'
Passes the internal table for variants
       IS_VARIANT                         = i_variant1
fetches different events into internal table i_events
       it_events                          = i_events[]
      TABLES
Passes data table for ALV display
        T_OUTTAB                          = I_TAB
     EXCEPTIONS
       PROGRAM_ERROR                      = 1
       OTHERS                             = 2
*&      Form  user_command
Form used to handle USER_COMMAND events
rf_ucomm: Function Code
rs      : Internal Table containing the selection information.
FORM user_command USING rf_ucomm LIKE sy-ucomm
                          rs TYPE slis_selfield.
data : v_mblnr like mseg-mblnr.
case rf_ucomm.
A custom pushbutton for record deletion is set in the GUI status.
When a record is selected , the field BOC for that record becomes 'X'.
The records are traced and deleted and the fields are refreshed( rs
of type slis_selfield is refreshed)
when '&DEL'.                 "Print button clicked.
    delete i_tab where box = 'X'.
     rs-refresh = 'X'.
When the user selects a row and presses the Select pushbutton ( user
defined ) from the application toolbar, the details of the document
will be shown in another ALV list
when '&SEL'.
  PERFORM SUB_SELECT_DOCUMENT.
  set parameter id 'MBN'  field  i_tab-mblnr.
  call transaction 'MB03'.
Ok code for double click is &IC1 for ALV report
when '&IC1'.
  perform sub_hotspot.
endcase.
ENDFORM.
*&      Form  SUB_HOTSPOT
      text
-->  p1        text
<--  p2        text
form SUB_HOTSPOT.
message i398(00) with 'Hello'.
endform.                    " SUB_HOTSPOT
