Hi everybody,
Does anyone know how to change the selection screen on a ABAP report that uses LDB ?
What I want to do is to suppress some fields and buttons and to add hidden fields.
Thanks for your help.

MODIFY SCREEN.

Change selection screen in LDB (KDF logical database - NOT HR)

Hi All,
Iu2019d like to use KDF logical database to keep the dynamic selections since user wants to use it but I need to change the selection screen itself. The existing variants for KDF donu2019t meet the user requirements. Some fields I need to hide some add. Like I want to u201Cremoveu201D the field u2018Posting periodu2019 (MONAT) (which is available in dynamic selection screen) and put it on the u201Cmainu201D selection screen.
Do I need to create my own logical database or there is a way around?
Could someone give me a practical advice or sample of solution?
Thanks a lot.

Thanks Himanshu,
I did as you suggested but problem is that it does not allow me to hide the whole block.
I have 3 filelds actually on block KD_0 I need to hide (its from selection screen of KDF logical database.)
SELECT-OPTIONS: KD_LIFNR FOR LFA1-LIFNR MATCHCODE OBJECT KRED.
SELECT-OPTIONS: KD_BUKRS    FOR LFB1-BUKRS.
SELECTION-SCREEN END OF BLOCK KD_0.
PARAMETERS KD_INDEX AS SEARCH PATTERN FOR TABLE LFA1.
What I did is below. I used sp instead of u201C=u201D since it has many screen for field KD_LIFNR(for frame, text etc).
And when I did just for KD_LIFNR it was hidden but when I did the same for KD_BUKRS it was not hidden . The field has stars u201C*********u201D in it.
Same happen with KD_INDEX. The name of the field is hidden but field not and it filled with ********. Do you have any ideas what it can be?
I debugged it to catch all screen names but no luck
loop at screen.
    if screen-name cp 'KD_LIFNR' or
    screen-name cp 'KD_BUKRS' or
    screen-name cp 'KD_INDEX' or
    screen-name = '%B000003_BLOCK_1000' or
    screen-name = 'SSCRTEXTS-FRAME_TEXT' or
    screen-name = 'SSCRTEXTS-MCID_TEXT' or
    screen-name = 'SSCRTEXTS-STRNG_TEXT' or
    screen-name = 'SSCRFIELDS-SEARCH_BTN' or
    screen-name = '%B025008_BLOCK_1000' or
    screen-name = '%F021010_1000' or
    screen-name = 'ALCUR' or
    screen-name = '%F022012_1000' or
    screen-name = 'EXCDT' or
    screen-name = 'SSCRFIELDS-UCOMM'.
      screen-invisible = '1'.
      modify screen.
    endif.
endloop.

How to Add a new fields in the selection screen of LDB.

Hi All,
I want to add a new fields in the selection screen of LDB & then i need to select the data for that fields.

Thanks

Hi
welcome to SDN forum
If you are designing your own LDB with your own tables you can define tree structure and then the selection screen for the tables
if you wants to modify the std LDB of SAp means take the access key and to modify that code
if you add the extra field you have to modify the where conditions in the code also
see the doc
A logical database is a special ABAP/4 program which combines the contents of certain database tables. You can link a logical database to an ABAP/4 report program as an attribute. The logical database then supplies the report program with a set of hierarchically structured table lines which can be taken from different database tables.
LDB offers an easy-to-use selection screens. You can modify the pre-generated selection screen to your needs. It offers check functions to check whether user input is complete, correct, and plausible. It offers reasonable data selections. It contains central authorization checks for data base accesses. Enhancements such as improved performance immediately apply to all report programs that use the logical database.
Less coding s required to retrieve data compared to normal internel tables.
Tables used LDB are in hierarchial structure.
Mainly we used LDBs in HR Abap Programming.
Where all tables are highly inter related so LDBs can optimize the performance there.

Reg : Selection-Screen in LDB's

hi,
Iam working on a report which uses Logical DataBase : PSJ.
Iam getting output based on the standard selection screen of LDB PSJ.
Now my requirement is :
I need to add a new field(select option) to the Selection screen and the output should be displayed based on new field select option values
how to do this?
Plz answer
Regards
vaja

Hi,
You simply add the check in the relevant GET event of the LDB.
For example, you may have an event for DOCUMENT as follows.
GET DOCUMENT.
check document-ref in s_ref.
S_REF being your new select option.
Hope this helps.

How to change Select-Optio ?

Hi ,
How to change Select-Option statement as a Parameter statement?

Hi,
Decalare it as
1)If you want your SELECT -OPTIONS to behave like parameters. USe the option.
SELECT-OPTIONS ..... NO INTERVALS NO-EXTENSION
REPORT abc.
DATA : v_enterpr(30) TYPE c,
v_divin(30) TYPE c.
SELECT-OPTIONS : s_enterp FOR v_enterpr NO INTERVALS NO-EXTENSION ,
s_divin FOR v_divin NO INTERVALS NO-EXTENSION .
2)If you want to have it as SELECT-OPTIONS.
Then
REPORT abc.
DATA : v_enterpr(30) TYPE c,
v_divin(30) TYPE c.
SELECT-OPTIONS : s_enterp FOR v_enterpr ,
s_divin FOR v_divin .
NO-EXTENSION
The user can only make an entry on one line. Calling the additional "Multiple Selection" screen is not supported and no pushbutton for this appears on the selection screen.
NO INTERVALS
The selection option is displayed on the selection screen without a 'to' field. The pushbutton for calling the "Multiple Selection" screen appears immediately after the 'from' field.
This addition thus allows you to generate a simplified display on the selection screen. This is particularly useful if you are not making any range selections for this selection option.
If u have both No-extension and No-interval it will behave like simple parameters stmt.

Omkar.

First: What is a GPO?
Second: jrv, that was not too helpful in general. someone should do some actual code.
Bob Blork - Mark as answer if it helped!
This is a forum for technicians and not for home users. GPO is what technical people use to manage Windows. THe script to do this is in the link I posted - how is that not helpful?
I know this is all over your head. I am curious as to why you would respond in a technical forum to a question you do not understand.
We do not provide free scripts. We also will point users at correct answers.
This is not a forum for homw users or for simple support questions. It is also a thread that has been answered for a long time. Perhaps you should start a new thread if you have an actual question about scripting.

How to pass selection screen parameters in text elements?

how to pass selection screen parameters in text elements?

don't you mean he other way around. Assign text-elements (selection texts) to select options?
This you do in the menu where you can find text-elements, selection texts.
menu Goto->text elements->selection texts.

Hi,
The selection screen parameters will be on an inputField, so try and get the is of the inputfield generated by doing View source...
And once you get the inputfield Id, you can read the value in the InputField(InF) by
using the following code...!
data : if_value type ref to cl_htmlb_inputfield.
data : variable type string.
if_value ?= cl_htmlb_manager=>get_data( request = request
                                            name    = 'inputField'
                                            id      = 'InF_ID_here'
       if if_value->value is not initial.
         variable = if_value->value.
       endif.
Hope this helps.

How to capture selection-screen values

Hi,
How to capture selection-screen values when user pressing F3 or Back button after the display of report.
Regards,
Bujji.

Hi Bujji,
select-option are actually ranges or more general internal tables with the structure:
SIGN:    'I'nclusive or 'E'xclusive
OPTION: 'EQ', 'BT', 'NE', 'GE', 'CP', ....
LOW:     low value of type of the curresponding "FOR table-field"
HIGH:     high value of type of the curresponding "FOR table-field"
You may just code:
TABLES: mara.
SELECT-OPTIONS s_matnr FOR mara-matnr.
LOOP AT s_matnr.
WRITE: / s_matnr-sign,
           s_matnr-option,
           s_matnr-low,
           s_matnr-high.
ENDLOOP.
If you find my answer useful, please don't forget the reward.
