SAP ABAP Process on Value Request

[@rettjaconomaili8201]

Hello , thank you so much for an explanation.
I have found in my environment a program where user can input the key word in the field, add an * , then press F4 and it returns the table with restricted values range. Maybe you know how to implement this?
P.s. unfortunately F4IF_INT... module is absent in my environment. To do an usual Search Help i used HELP_VALUES_GET_WITH_TABLE

Thanks for your kind words Happy that my videos were helpful to you.
To implement a custom F4 help in your ABAP environment without using the `F4IF_INT_TABLE_VALUE_REQUEST` function module, you can utilize the `HELP_VALUES_GET_WITH_TABLE` function module or create your own custom search help. Here's how you can do it using `HELP_VALUES_GET_WITH_TABLE`:
1. **Define the Internal Table with Possible Values**: Create an internal table that contains the values you want to display in the F4 help.
2. **Implement the F4 Help**: Use the `HELP_VALUES_GET_WITH_TABLE` function module to display the F4 help dialog with your restricted values.
Here’s an example to guide you through the process:
### Step-by-Step Example
1. **Define the Internal Table**:
```abap
TYPES: BEGIN OF ty_value,
key TYPE char10,
value TYPE char50,
END OF ty_value.
DATA: lt_values TYPE TABLE OF ty_value,
ls_value TYPE ty_value.
```
2. **Populate the Internal Table**:
```abap
ls_value-key = 'A001'.
ls_value-value = 'Value 1'.
APPEND ls_value TO lt_values.
ls_value-key = 'A002'.
ls_value-value = 'Value 2'.
APPEND ls_value TO lt_values.
ls_value-key = 'A003'.
ls_value-value = 'Value 3'.
APPEND ls_value TO lt_values.
```
3. **Implement the F4 Help in the Event**:
```abap
MODULE value_request INPUT.
DATA: lt_return TYPE TABLE OF ddshretval,
lt_dynpfields TYPE TABLE OF dynpread,
lv_repid TYPE sy-repid,
lv_dynnr TYPE sy-dynnr.
lv_repid = sy-repid.
lv_dynnr = sy-dynnr.
CALL FUNCTION 'HELP_VALUES_GET_WITH_TABLE'
EXPORTING
search_table = lt_values
title = 'Select a Value'
IMPORTING
return_tab = lt_return
TABLES
dynpfields = lt_dynpfields
EXCEPTIONS
others = 1.
IF sy-subrc = 0.
READ TABLE lt_return INDEX 1.
IF sy-subrc = 0.
LOOP AT SCREEN.
IF screen-name = 'YOUR_FIELD_NAME'.
screen-value = lt_return-fieldval.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
ENDIF.
ENDIF.
ENDMODULE.
```
In this example:
- An internal table `lt_values` is populated with possible values.
- When the user presses F4 on the field, the `HELP_VALUES_GET_WITH_TABLE` function module is called to display the possible values.
- The selected value is then returned and displayed in the input field.
### Using `HELP_VALUES_GET_WITH_TABLE`
Ensure that your program is structured to handle the F4 help properly. If the function module `HELP_VALUES_GET_WITH_TABLE` is not available, you might need to create a custom dialog or search help to achieve similar functionality.
### Custom Search Help
If you prefer to use custom search help, you can define one in the Data Dictionary (SE11) and link it to your field.
1. **Create Search Help in SE11**:
- Go to SE11.
- Select Search Help and create a new one.
- Define the selection method and fields.
- Save and activate the search help.
2. **Link Search Help to Your Field**:
- Go to the screen where your field is defined (SE51).
- Assign the search help to the field.
This method leverages standard SAP capabilities and provides a robust solution for dynamic F4 help.
