Definition
During the input help process, a number of timepoints are defined that each define the beginning of an important operation of the input help process.
If the input help process is defined with a search help having a search help exit, this search help exit is called at each of these timepoints. If required, the search help exit can also influence the process and even determine that the process should be continued at a different timepoint.
The following timepoints are defined:
- SELONE
Call before selecting an elementary search help. The possible elementary search helps are already in SHLP_TAB. This timepoint can be used in a search help exit of a collective search help to restrict the selection possibilities for the elementary search helps.
Entries that are deleted from SHLP_TAB in this step are not offered in the elementary search help selection. If there is only one entry remaining in SHLP_TAB, the dialog box for selecting elementary search helps is skipped. You may not change the next timepoint.
The timepoint is not accessed again if another elementary search help is to be selected during the dialog.
- PRESEL1
After selecting an elementary search help. Table INTERFACE has not yet been copied to table SELOPT at this timepoint in the definition of the search help (type SHLP_DESCR_T). This means that you can still influence the attachment of the search help to the screen here. (Table INTERFACE contains the information about how the search help parameters are related to the screen fields).
- PRESEL
Before sending the dialog box for restricting values. This timepoint is suitable for predefining the value restriction or for completely suppressing or copying the dialog.
- SELECT
Before selecting the values. If you do not want the default selection, you should copy this timepoint with a search help exit. DISP should be set as the next timepoint.
- DISP
Before displaying the hit list. This timepoint is suitable for restricting the values to be displayed, e.g. depending on authorizations.
- RETURN (usually as return value for the next timepoint)
The RETURN timepoint should be returned as the next step if a single hit was selected in a search help exit.
It can make sense to change the F4 flow at this timepoint if control of the process sequence of the Transaction should depend on the selected value (typical example: setting SET/GET parameters). However, you should note that the process will then depend on whether a value was entered manually or with an input help.
- RETTOP
You only go to this timepoint if the input help is controlled by a collective search help. It directly follows the timepoint RETURN. The search help exit of the collective search help, however, is called at timepoint RETTOP.
- EXIT (only for return as next timepoint)
The EXIT timepoint should be returned as the next step if the user had the opportunity to terminate the dialog within the search help exit.
- CREATE
The CREATE timepoint is only accessed if the user selects the function "Create new values". This function is only available if field CUSTTAB of the control string CALLCONTROL was given a value not equal to SPACE earlier on.
The name of the (customizing) table to be maintained is normally entered there. The next step returned after CREATE should be SELECT so that the newly entered value can be selected and then displayed.
- APP1, APP2, APP3
If further pushbuttons are introduced in the hit list with function module F4UT_LIST_EXIT, these timepoints are introduced. They are accessed when the user presses the corresponding pushbutton.
Note: If the F4 help is controlled by a collective search help, the search help exit of the collective search help is called at timepoints SELONE and RETTOP. (RETTOP only if the user selects a value.) At all other timepoints the search help exit of the selected elementary search help is called.
If the F4 help is controlled by an elementary search help, timepoint RETTOP is not executed. The search help exit of the elementary search help is called at timepoint SELONE (at the moment). This search help exit should not do anything at this timepoint. Any preparatory work should be carried out at timepoint PRESEL1.
