Dynamic selection screen parameter

Hello All,
I am facing problem in dynamic parameter declaration in selection screen. My requirement is as below,
Want to have 2 parameters in selection screen and based on first parameter (table fields) selected value, the second parameter (display the value of the selected table field) should display value of the selected field.
The problem is the second paramter type should be of first parameter selected field.
How to declare parameter dynamically after getting the first parameter selected field.
Thanks in Advance.
Regards,
Suganya.

hi
You may use the Runtime Type Information(RTTI)/ RTTS to get the parameter type at runtime
Process would be :
> create a variable: l_var type ref to CL_ABAP_ELEMDESCR.
> l_var ?= cl_abap_typedescr=>describe_by_data(parameter).
> loop at l_var->components into wa
> process.
> endloop

F4 help for a selection screen parameter with filename created dynamically

Hi All,
          I have a requirement where in an F4 help should be present for a selection screen parameter. After selecting the filepath and clicking OK button on the Dialog, the filename should be dynamically get created in the selection screen parameter field. For example:
if the path is D:\DOCS then at the end of DOCS the filename should automatically get populated.
Like below string:
D:\DOCS\new.txt
Is there any function module or method which does this kind of activity.

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.

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.

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

How to generate dynamic selection-screen?

Hi all,
I have two radio buttons on selection-screen.
If user-selects the one, Then under the radio button another parameter should be displayed

Problems creating dynamic selection screen

Hi all,
i'm trying to dynamically generate a selection screen and show it as subscreen using the two function modules FREE_SELECTIONS_INIT and FREE_SELECTIONS_DIALOG. I call the function modules in the PBO of the therefor defined subscreen. The FREE_SELECTIONS_DIALOG fm has the two import parameter "as_subscreen" and "as_window". If i use the "as_window" parameter the selection screen comes up as popup. If i use the "as_subscreen" parameter, i can't see anything in my defined subscreen.
Any suggestions ?
Thanks in Advance
Dirk

Hi,
The above requirement is not possible without using logical database.
The reason is that the compiler identifies the below syntax only inside a LDB program .
SELECTION-SCREEN DYNAMIC SELECTIONS
                 FOR {NODE|TABLE} node [ID id].
The above syntax creates a subscreen container on the standard selection screen of the program during generation
and we are able to view the dynamic selections icon on the selection screen.
Hence it is not possible to use the FM 'FREE_SELECTIONS_DIALOG' as a subscreen without using a
logical database of the relevant table.
However if you dont want to create a new LDB for each table, there is a trick which needs to be performed
once in your SAP system and all custom programs can use this FM to create a dynamic selection screen
as a subscreen of the standard selection screen.
The prerequisite steps are as follows:
1: Create a dummy / test database table in SE11 with a single field i.e. for example mandt , matnr
2: Create a new logical database program for this table in SE36. Save and activate.
This will create dynamic selections for the fields of the table created in step 1.
Steps to be followed in the required custom ABAP program to create the dynamic selection screen as a subscreen.
A: Include the LDB program created in step 2, in the attributes of the custom ABAP program.
Now when you execute the program, you can see the dynamic selection icon for the dummy table created in step 1.
B: In your custom program we need to suppress the icon for 'Dynamic Selections' from the standard selection screen.
   We need to perform this action, because the 'Dynamic Selections' icon always triggers a call to the
   dynamic selection screen of the included LDB progam. ( In our case a dummy table created in step 1 ).
   Whereas we want to trigger a call of the dynamic selection screen of our desired table.
   Logic is as follows:
   In 'AT SELECTION-SCREEN OUTPUT' event call the FM RS_SET_SELSCREEN_STATUS to exclude the fcode 'DYNS'.
C: Add a pushbutton / checkbox on your selection screen to trigger a call to the FM 'FREE_SELECTIONS_INIT' &
   'FREE_SELECTIONS_DIALOG' in the 'AT SELECTION-SCREEN' event.
D: When the user clicks the pushbutton / checkbox for dynamic selections call the above 2 FM for the desired table
    with the AS_SUBSCREEN flag of FREE_SELECTIONS_DIALOG = 'X'
Result: Your dynamic selections screen will be created as a subscreen of the standard selection screen and not as a pop-up.
Advantage: With the creation of the single custom table & LDB, you are now able to create dynamic selections as subscreen
in any program in the system. All we need to do is follow the steps A, B & C in each program.
Note: Your other restrictions with dynamic selection screen ie. submit in background , save as variant still remain and
you need to handle them accordingly.
let me know if you need sample code.

Bhawit Kumar

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 :
How to hide the selection screen of a Logical datebase?

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.

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

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.

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.
