Dynamic Selection option in the selection screen

Hi ,
I have a requirement like this ....
The user wants some fields to be default available in the selection screen. But they also want to be able to select the data based on additional fields (all the remaining fields ) which they want to see in the dynamic selection .
The basic list for selections should be limited to the fields listed in the specifications provided to me and the remaining fields should be made available through the dynamic selection option.
In the transaction FBL3N , this facility is provided.
Kindly help me with this..
thanks,
Sumit .

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.

Dynamic selection screen fetching the value from table fields

hi gurus,
i have one table say ztable...and i should create a dynamic selection screen which should populate the selection screen by the table field names.
example..if i have 3 fields im my table..my selection screen should have three selection option fields..and in future if i add one more field in my table it should automatically create another slection-option in selection screen..
thanks
Sudheer

Do you mean like SE16 works. If so, you should notice that if you amend the selection fields, the screen program is actually re-generated.
That is what is happening. A program is being created and re-generated.
To create a dynamic selection screen in a single program is not possible ( I may be wrong ). If it is possible, then you would have problems in defining selection screen field names and using them.

How to add a new Field in the Dynamic Selection screen section.

HI,
There is a requirement in which I need to add a field in existing program of dynamic selections.
I need to add a field KNKK-DBRTG (Customer Rating) in dynamic selections screen of some existing report
which has a dynamic selection screen with other fields like customer account, company code etc. Along with this i need to add Customer rating field also in the selection screen.
I have used GET KNKK statement to select this in the Dynamic selection screen. But I need to make it appear
on the screen.
LDB used is the Customer Database.
I have added GET KNKK statement after GET KNA1 statement.
Can any one help me how we can make this rating field appear in the selection screen.
With the GET statement Credit control area Fields can be selected in the selection screen but I have to permanantly add the field in the selection screen.

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

Adding a BSEG field to the FB03 dynamic selection screen

Hello,
We have a requirement wherein we want to add a field from BSEG in the dynamic selection screen of FB03.
We found that the logical database behind this is BRF. So we created a u2018CUSu2019 selection view for the logical database and added the field from BSEG to the functional group
and checked the checkbox u201CPreselectu201D for it to appear automatically in the FB03 screen.
But we still couldnu2019t see the field in FB03 dynamic selection.
On analysis, we found that only tables are that are defined in the nodes (Extras  Selection views) can be used to create the dynamic selection and BSEG was not available
as one of the node. So we added BSEG as one of the node by adding the below code to the SELECTION of the logical database.
SELECTION-SCREEN DYNAMIC SELECTIONS FOR TABLE BSEG.
Even after that, we couldnu2019t see the field from BSEG in the dynamic selection.
Are we missing anything here?
I see many threads here on similar lines but no one has posted the exact step. Any help is highly appreciated.
Thanks a lot.

Suganya

Hi
If you want to take the line item details than you can refer these t-codes rather than customizing.
S_AC0_52000887 - Receivables: Profit Center
S_AC0_52000888 - Payables: Profit Center
S_ALR_87012332 - G/L Account Statements
Here by using the dynamic selection you can get the results. Use object list display and select the layout for more fields.
Thanks

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

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.

Need to generate dynamic selection screen

Hi,
'am looking for a requirement in ABAP Programming which is feasible!
While executing my report, std. selection screen ( 1000) gets displayed and it gives the output list which consists of only one field that will have TABLE NAMES. Once the user selects any one of the record on this output list, I need to display another screen ( selection screen ) with all the key fields of that table that got seleted.
How do I populate a dynamic selection screen by passing TABLE NAME as parameter with all the keyfields of that table as select-options.
Awaiting your quick positive reply..

Alv Output after dynamic selection screen

Hi,
First of all, you should check your radiobutton instead of select-option...
Then you will have to build the output internal table dynamically based on the option chosen. There are lot of example on SDN...

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.

Dynamic Selection screen in FDK43 transaction

HI,
The transaction FDK43 has a dynamic selection screen used from LDB DDF .It does not show all selections views in the dynamic selection but when I test the LDB from se36 its shows all the selections in dynamic selections.
Any idea why it is not showind in the transaction FDK43 ??
Regards,
Shital

Hi,
LDB fields are nothing to do with Dynamic Selection. It is not necessary that all the field of LDB should be visible in Dynamic Selection. FDK43 is a standard screen and SAP has designed the dynamic selection with limited option. If you want additional fields, you need to do the enhancement with the help of ABAPer.

Ravi

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?

How to use dynamic selection screen inputs in main program

hi all,
its a report where in it calls one dynamic selection screen( user need to enter the parameters here) after that i need to use those inputs for some check, can any buddy help how to use/ get that input parameters into main program.
regards,

Hi,
i think u have created that dynamic selection screen in seperate program and calling to ur main program.instead of that u just create that synamic selection screen program as include program and include it in ur main program.
or u need to use set/get parameter id concept.
