ALV Grid display on SAP Module Pool

Question

Hi All,
I need to create a module pool screen, which would have 2 different ALV's. The format of screen would be something like:
Some I/Ofields
ALV 1
ALV 2
How can I restrict the display of ALV data to the areas predefined on the screen?
What type of component is required to be defined on module pool for restricting ALV to that particular area?
or , while displaying ALV (i am using ALV FM's) is there any addition that is required?
Regards-
Harmeet.

Answer 1

Hi,
There are number of examples in net, SCN and wherever you look for.
Basically what you need is:
- a screen
- your screen fields placed on top of this screen
- custom control on this screen underneath your screen fields
- in PBO module of that screen you need to create splitter container
- by means of this splitter container you get two containers
- in both you place your ALVs
For details how to implement this please refer [Displaying two ALVs on the screen|http://sample-code-abap.blogspot.com/2008/06/displaying-two-alv-grid-on-screen.html].
Note!
In above example you have such coding:
   CREATE OBJECT ob_custom
      EXPORTING
        container_name = 'CONTAINER' .   "CONTAINER is the name of CUSTOM CONTROL placed on screen (as exlapained above)
Alternatively you can use two custom controls for each ALV separately. This will ensure that they have fixed position on screen (size too). Using splitter container as in the example it is, however, more flexible as you hold two alvs in one container and have nice splitter, which you can drag and rezise ALVs vertically. Custom container remains unchanged and is fixed on screen. It also defines boundaries of your ALVs (we can call it an area)
I don't think you can achieve this using standard FMs, so you must use this OO aproach.
