Generate Selection Screen as Popup dynamically

former_member301120 — Fri, 17 Oct 2008 07:35:27 GMT

Hello to all,

is there a way to generate a selection screen popup at runtime dynamically?

Is there any guide, that explains how "generate dynpro" has to be used?

Thanks

Christian

Hello,

This there is an option with key word 'Window staring and window ending'.

or Creat the screen and call the screen when ever you want the selection screen.

Hello,

I know how to call a dynpro as popup.

But my problem is, that I have to generate this selection on runtime, as then all fields are known like Tx SE16.

hi,

you can create a selection screen as a pop up using this code. Here 200 is just a arbitary screen number which i have given.

REPORT ZSDSDSD.

tables : vbak.

SELECTION-SCREEN BEGIN OF SCREEN 200 AS WINDOW.

SELECT-OPTIONS : s_vbeln FOR vbak-vbeln,

s_ernam FOR vbak-ernam,

s_erdat FOR vbak-erdat.

SELECTION-SCREEN END OF SCREEN 200.

CALL SELECTION-SCREEN '0200' STARTING AT 10 10.

Hello Rajneesh,

I'm looking for a way where the selection-fields could be defined at runtime.

HI,

you can define(not create) multiple selection screens and then call them according to your data or conditions . for example,

tables : vbak.

data flg type c value 'T'.

SELECTION-SCREEN BEGIN OF SCREEN 200 AS WINDOW.

SELECT-OPTIONS : s_vbeln FOR vbak-vbeln,

s_ernam FOR vbak-ernam.

SELECTION-SCREEN END OF SCREEN 200.

SELECTION-SCREEN BEGIN OF SCREEN 201 AS WINDOW.

SELECT-OPTIONS : s_vbeln1 FOR vbak-vbeln.

SELECTION-SCREEN END OF SCREEN 201.

if flg = 'Y'.

CALL SELECTION-SCREEN '0200' STARTING AT 10 10.

ELSE.

CALL SELECTION-SCREEN '0201' STARTING AT 10 10.

ENDIF.

Hi Christian,

at the moment I don´t have a solution for you but since 1 hour, I have nearly the same problem...

Perhaps I can give you an idea to solve it, but I am not sure if it works. I must test it for my own...

My plan is to build 1 Reports and a functionality to build a dynamic report, for example a persistent abap class.

-> Report A: executes the class (FM or something else) which generates the sourcecode of the dynamic Report.

-> The Class reads the metadata which fields are required on the dynamic selection screen (in my case from a database table)

-> Then I build a source code with correct syntax into an internal table, which contains the code of the selection-screen.

-> With this source code i generate a persistent report ( statement: insert report )...

-> Then Report A calls the generated Report via SUBMIT statement.

-> for the transport of the data from the selection screen of the "dynamic" Report to Report A

I would try to do use the ABAP-Memory...

-> perhaps it is necessary to generate an "empty" dynamic report with contains an selection screen

so that the compiler can check the submit statement. Then the "dynamic" report becomes overwritten

on execution of Report A.

I hope, this works 🐵

I would try it this way and post it later (next days) if it works...

Regards,

Oliver

/XXX/ztsys_dssfield has the following line structure:


FIELDNAME	CHAR08
REFTABLE	TABNAME
REFFIELD	FIELDNAME
BASICTYPE	CHAR01
DESCR	CHAR30_BRO

I hope It helps you!

I'm looking for a way to do the same in a selection-screen Pop-Up.

Hi Christian,

what a nice surprise.

Thank you very much for your source code.

I think I can use some parts of it - unfortunately our basis release does not support shared objects

That´s why I "want" to use ABAP-Memory...

With regards,

Oliver
