Generate fields on the selection screen automatically

Former Member — Wed, 06 Aug 2008 08:59:07 GMT

Hi,

I'd like create some fields on my selection screen automatically using an information filled in the selection screen too.

For instance : I enter a table name, and my selection screen is autommatically filled with all the primary key fields of this table.

Do know, how i can do that?

Thx in advance.

u have to write the code under the event..

AT SELECTION-SCREEN OUTPUT.

there u can make some fields invisible or invisible, based on any value entered on the selection screen.

u can write the same in the below way..

if pa_char eq 'X'.

LOOP AT SCREEN.

if screen-name = 'FILED_NAME'.

screen-invisible = 1.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

else.

LOOP AT SCREEN.

if screen-name = 'FILED_NAME'.

screen-invisible = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

endif.

wat this will do is when u enter value 'X' in the parameter pa_char, the screen field with name FIELD_NAME will become visible..

Hope this idea helps u out...

My problem is not to switch an existing field from invisible to visible...

As I said, the fields don't exist, I have to create these fields dynamically on the selection screen.

When I enter a table name, I'd like that all the primary key fields will be created automatically on my selection screen.

The solution may be to call an other selection screen? But how?

In At selection-screen output use CALL SELECTION-SCREEN <sel screen number>.

You will need to define multiple selection screen in your program / include and call it accordingly.

If you are asking for dynamic code to define selection-screen and it's component, i doubt if that can be done with conventional ABAP.
