Interactive list

Former Member — Fri, 10 Oct 2008 11:36:09 GMT

I have a task in which I am displaying material and plant in the basic list. The requirement is, if i click on the material, then it should display the material details in a secondary list and if i click on plant, then it should display the plant details in another secondary list. How to achieve this? can someone suggest me the code for this?

Hi,

For this requirement ALV output suits best. Because in ALV you will not only be able to select the row on which you have clicked you can also select the column on which you have clicked suiting your requirement better.

If you need more details on how to do this go to FM 'REUSE_ALV_GRID_DISPLAY' and select the documentation on the right hand corner. In the documentation check for the USER_COMMAND Details which will help you achieve this.

Regards,

Pramod

Hi Pramod, Thanks for your suggestion. But I am not supposed to use ALV in this task.

Hi Ashwini,

If you are only displaying plant and material then there is an alternative. When you double click on the basic list then popup a confirmation message asking the user if he wants to drilldown on Plant or material. This can be done using an FM i am not sure which, you can search for it using * POPUP * in SE37.

If he selects Material show material details on next list. Else if he states plant then show the plant details.

Hope this helps.

PS : The FM is 'POPUP_WITH_2_BUTTONS_TO_CHOOSE'

Regards,

Pramod

Lists are displayed in a special container screen. As with all other screens, you can link a dialog status to it using the SET PF-STATUS statement. In the dialog status, you link function codes to function keys, menu entries, icons in the standard toolbar, and pushbuttons in the application toolbar.

On a normal screen, a user action triggers the PAI event. In the screen flow logic, you code a processing block that calls ABAP dialog modules in this event. In list processing, the event is intercepted by the list processor and processed. Instead of calling dialog modules, one of the three following list events may be called, depending on the function code triggered by the user.

AT PF<nn> (obsolete)

AT LINE-SELECTION

AT USER-COMMAND

If you have written the corresponding event blocks in your program, they are executed. You can access the function code in the system field SY-UCOMM.

The output from any list statements that you write in these event blocks is written to detail lists. With one ABAP program, you can maintain one basic list and up to 19 detail lists.

Check this sample code..
