* STEP SELONE  (Select one of the elementary searchhelps)
*"----------------------------------------------------------------------
* This step is only called for collective searchhelps. It may be used
* to reduce the amount of elementary searchhelps given in SHLP_TAB.
* The compound searchhelp is given in SHLP.
* If you do not change CALLCONTROL-STEP, the next step is the
* dialog, to select one of the elementary searchhelps.
* If you want to skip this dialog, you have to return the selected
* elementary searchhelp in SHLP and to change CALLCONTROL-STEP to
* either to 'PRESEL' or to 'SELECT'.
  IF CALLCONTROL-STEP = 'SELONE'.
*   PERFORM SELONE .........

*"----------------------------------------------------------------------
* STEP PRESEL  (Enter selection conditions)
*"----------------------------------------------------------------------
* This step allows you, to influence the selection conditions either
* before they are displayed or in order to skip the dialog completely.
* If you want to skip the dialog, you should change CALLCONTROL-STEP
* to 'SELECT'.
* Normaly only SHLP-SELOPT should be changed in this step.

*"----------------------------------------------------------------------
* STEP SELECT    (Select values)
*"----------------------------------------------------------------------
* This step may be used to overtake the data selection completely.
* To skip the standard seletion, you should return 'DISP' as following
* step in CALLCONTROL-STEP.
* Normally RECORD_TAB should be filled after this step.
* Standard function module F4UT_RESULTS_MAP may be very helpfull in this
* step.

* This step is called, before the selected data is displayed.

* If you want to get the standard display dialog afterwards, you
* should not change CALLCONTROL-STEP.
* If you want to overtake the dialog on you own, you must return
* the following values in CALLCONTROL-STEP:
* - "RETURN" if one line was selected. The selected line must be
*   the only record left in RECORD_TAB. The corresponding fields of
*   this line are entered into the screen.
* - "EXIT" if the values request should be aborted
* - "PRESEL" if you want to return to the selection dialog
