Dynamic selection-screen in a method

<b>I need to generate selection-screen dynamically from a method of the class.</b>
There are can be select options and parameters on the selection-screen.
At runtime, it's needed to generate a program containing selection-screen and pass a table into the program in order to get results of the user selection (there should be a query to the database in the program). Notice, that dynamic program is called from a method of the class.
Best regards.

How to generate a dynamic selection-screen

Hi folks,
I have a itab with all fields and descriptions of a database-table. Now i want to generate a selection screen dynamically. I want to create a select-option for every field of the table.
First I read all fields of a database table into my intern table:
CALL FUNCTION 'DDIF_FIELDINFO_GET'
EXPORTING
    tabname              = 'database_tabname'
TABLES
    dfies_tab            = it_tabname_fields.
Then I tried to generate a dynamic selection-screen with a select-options statement per field of the itab, but it doesn't work:
SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE text-001 NO INTERVALS.
LOOP AT it_tabname_fields INTO s_tabname_fields. "should be 14 loops and 14 lines
SELECTION-SCREEN BEGIN OF LINE.
SELECTION-SCREEN COMMENT (25) s_tabname_fields-SCRTEXT_S FOR FIELD var1. "the name of the field should be set dynamically from the itab
SELECT-OPTIONS var1 FOR tabname-s_tabname_fields-fieldname. "s_tabname_fields-fieldname should be set dynamically for each line
SELECTION-SCREEN END OF LINE.
ENDLOOP.
SELECTION-SCREEN END OF BLOCK b2.
I know that this doesn't work but it should help you to understand what i want to do. It doesn't create more than one select-option (it should be 14 because there are 14 lines in the table) and it doesn't get the values from the table.
I hope you can help me...

Sebastian

hi
Firstly, have a look at the following code to see how this can be implemented -
REPORT ZTEST.
perform test.
class test definition.
public section.
    methods: create_screen.
endclass.
class test implementation.
method create_screen.
    data: report_line(72),
           report_source like table of report_line.
    data: err_message(240),
          err_line type i,
          err_word(100).
    report_line = 'REPORT TEST.'.
    append report_line to report_source.
    report_line = 'PARAMETERS: P_TEST TYPE I.'.
    append report_line to report_source.
    report_line = 'START-OF-SELECTION.'.
    append report_line to report_source.
    report_line = 'WRITE : P_TEST.'.
    append report_line to report_source.
    syntax-check for report_source message err_message
                                   line    err_line
                                   word    err_word.
    if err_message is initial.
      INSERT REPORT 'ZZZTESTZZZ' FROM REPORT_SOURCE.
      SUBMIT ZZZTESTZZZ VIA SELECTION-SCREEN AND RETURN.
    endif.
endmethod.
endclass.
form test.
data test type ref to test.
CREATE OBJECT TEST.
call method test->create_screen.
endform.
As you can see, the report is being written dynamically. Once the INSERT REPORT statement is executed, the program is available. you can you external subroutine calls to pass the data between the programs now.

How to deal with dynamic selection screen elements when macros are used?

Hello experts,
This is regarding the dynamic selection screen elements. Actually the requirement is to modify the existing standard report program RFUMSV00 by copying it into a Z report, adding a few selection screen elements and new fields in the output. I actually did everything required except for the one thing that is going out of my reach.
There are a certain fields which are coming when they are not supposed to get displayed. I don't understand the code because of its obsoleteness. Neither can I debug it because it is just data declaration.
This is the code where there is a fault. If I copy the entire code into a new Z report, I'm getting new fields like Entry Date, Document Type, Reference Transaction, Reference key, Logical system.
DEFINE selection_screen_line.
selection-screen: begin of line.
parameters &3 like &4 default 'X' modif id mc4.
selection-screen: comment (30) &1 for field &3 modif id mc4.
selection-screen: comment pos_low(10) text-019
                    for field &2 modif id mc4. "neu
parameters &2 like rfums_alv-variante modif id mc4.
selection-screen:
      position pos_high.
selection-screen: pushbutton (15) text-028
                    user-command &5 modif id mc4.
selection-screen end of line.
END-OF-DEFINITION.
Kindly, suggest me the right solution.

In the program attributes ( SE38 > RFUMSV00 > GOTO > Properties ), you will find a logical database BRF declared. The include DBBRFSEL is part of the selection screen of this logical database.
The selection screen is actually the selection screen of this logical database.
Under the Logical Database field, there is a Selection screen field where you can input which selection screen of the logical database to be used.
But, this is just to change the selection screen that is displayed. To completely suppress it you need to remove logical database declaration from the properties of the program and call it inside your program through function module.
You cannot just remove it from the declaration because many of its variables are used in the program.
So call it using function module as the first step in INITIALIZATION section of the program.
The syntax and function module to call it in your program can be found in the following thread :

Hi,
So you need that this new field have data in old records?
1.- If you are in BI 7.0 and the logic or data for that New field are in the same Dimension, you can use a Remodeling to fill it. I mean if you want if you want to load from a Master Data from other InfoObject in the same Dim.
2.- If condition "1" is not yours.
First add the new field, then create a Backup Cube (both cubes with the new field) and make a full update with all information in the original Cube. The new field willl be empty in both cubes.
Create an UR from BackUp_Cube to Original_Cube with all direct mapping and create a logic in the Start Routine of the UR (modiying the data_package) you can look for the data in the DSO that you often use to load.
To do that both cubes have to be Datasources ( right click on Cube-> aditional function-> and I think is "Extract Datasource")
Hope it helps. Regards, Federico

Exclude one field from Logical Database's dynamic selection screen

Hi Guru,
I have a requirement to amend a program to exclude the document number field (bsik-belnr) from the dynamic selection-screen of the logical database KDF(Vendor Database) so that the program will not filter according to the document number.
I have use the below syntax in my zprogram.
selection-screen exclude select-options: doc-no.
However I get syntax error "The addition EXCLUDE is only allowed in INCLUDE DBKDFSEL".
Please advice.
Best Regards,
Fung

The selection part of the logical database defines input fields for selecting data.
          The runtime environment displays these on the selection screen when you run an executable program linked to the logical database.
          Include called DB<ldbname>SEL.
        SELECTION-SCREEN BEGIN OF VERSION ver TEXT-xxx.
                                                                SELECTION-SCREEN EXCLUDE ... .
                                                SELECTION-SCREEN END OF VERSION ver.
Defines a selection screen version (with a three-character name ver ). Between BEGIN OF VERSION and END OF VERSION , you can exclude selection screen objects for the version ver , i.e. remove them from the selection screen with SELECTION-SCREEN EXCLUDE.
          SELECTION-SCREEN DYNAMIC SELECTIONS FOR TABLE dbtab
If one of these tables is active in the report (i.e. it is declared under TABLES or lies somewhere on the path from the root of the database hierarchy to a table declared with TABLES ), a pushbutton called 'Dynamic selections' appears on the selection screen.

Need to disable one of the select-options in dynamic selection screen

Hi,
we have copied the Standard program: RFDOPR00 into Z, my requirement is to disable one of the select-options in dynamic selection screen for ex: Reason code(User shouldnot able to enter anything in it).
Can anyone please tell me the procedure to do it... I had tried using at selection-screen but it doesnt work as it in 'LOOP AT SCREEN', i am not able to capture the Parameter name(screen-name).
Thanks,
Ravi

Hi,
Get inside your selection screen, by executing your program.
Now type /h in the field where you enter transaction code and press enter.
Now again press enter, this will take you debugger starting from your Selection screen.
You might be knowing this, still if you are not aware of this, this might be a valuable tip.
From here , you can trace your Parameter name.

How to retrieve values from Dynamic Selection screen while using LDB - PSJ

I am having problem in PSJ Logical database. In a custom report which is using PSJ LDB, we are using PROJ and PRPS_R tables.
When I run program it displays one dynamic selection screen, there we are giving selection criteria for PRPS (Master data WBS element) - Created on (giving some range like 2011/01/01 to 2011/01/31).
So I want to display all WBS element which are created during the period (2011/01/01 - 2011/01/31).
How do I retrieve the select-option low and high value of the field Created on Of WBS element if we Select data from any table based on this condition.
Please help me.
Thanks.

in fact you don't have to get the values, you only need to tell to the program to take them into account :
GET PRPS.
CHECK SELECT-OPTIONS.

Passing values to a dynamic selection screen via a report

Hi,
I have the following problem and need to seek your expertise urgently.
In my program, I need to call another report by passing in parameters to the selection screen of other report. However, I could not pass values into a dynamic selection screen. I tried to use submit (report) with free selection but do not know how it works.
Currently, I tried calling the function RS_REFRESH_FROM_DYNAMICAL_SEL and FREE_SELECTIONS_RANGE_2_EX. Using the object the first function has returned to me, I tried to append values such as fieldname etc to it. However, I realised the field names of a dynamic selection screen keeps changing. So I would not know how to pass a particular value to a selection field.
Appreciate any help given.
Thanks,
CK

Hello CK,
Are you using logical database in your selection screen program attributes? If it is, look at include file DBxxxSEL for parameter named xxxDYNSE where xxx = logical database. Debug the program that has that dynamic selection, and look at field xxxDYNSE. This should give you a hint on how to populate the parameter when you submit the program.

Dynamic selection screen

Hello all,
I have a requirement to create a 'dynamic' selection screen with 2 sections(vertical).
The first section contains set of selection options for which the type comes from the values stored in the internal table(populated at runtime). The second section contains checkbox corresponding to each selection option generated/created in the first section mentioned above.
So the number of fields and checkboxes to be created are identified only at the runtime.
Note: I already tried to use FMs FREE_SELECTIONS* but it is not serving my purpose.
Looking forward to your inputs.
Thanks & Regards,
Rajat
Edited by: rajat.sap123 on Feb 7, 2012 7:18 PM

Why don't you use the At selection-screen output event.
As i have understood your scenario you have two sections. with the first one containing the select-options. The second will change on basis of the first section selection.
Hope it helps you.
Elaborate a bit more so i can paste a code.

Specific criteria in dynamic selection screen.

Hi experts.
I have a requirement to build dynamic selection screen fields. For these I would like to use FREE_SELECTIONS_INIT and FREE_SELECTIONS_DIALOG function modules.
The problem is that all fields could be single field or as a range... Is there any chance to make specific fields (DATS) as a single field and others as a range ?
Thanks a lot.
Daniel.

yes
you need to pass fields in parameter FIELDS_TAB of function FREE_SELECTIONS_DIALOG
in this structure you have the field type P or S
