How to retrieve data using logical database and custom select options

Hi all,
I have a selection screen which is displayed by logical database PSJ and I have two select options of my own. I need to retrieve data based on both selection screen of logical database and my own select options. How can I do it?
Thanks in advance.

Hai Gupta
Check the following Document & Links
1. A logical database is in fact
a program only.
2. This LDB provides two main things :
a) a pre-defined selection screen
which handles all user inputs and validations
b) pre defined set of data
based upon the user selection.
3. So we dont have to worry about from
which tables to fetch data.
4. Moreover, this LDB Program,
handles all user-authorisations
and is efficient in all respects.
5. tcode is SLDB
good info about Logical Database. you can check the link.

Re: How to Create and Use ldb in reports?
Re: Logical databases
http://help.sap.com/saphelp_46c/helpdata/en/9f/db9bed35c111d1829f0000e829fbfe/frameset.htm
Functions for displaying and changing logical databases:
Call Transaction SE36 or
Choose ABAP Workbench -> Development -> Programming environ. -> Logical databases
Interaction between database program and report:
During program processing, subroutines are performed in the database program and events are executed in the report.
To read data from a database tables we use logical database.
A logical database provides read-only access to a group of related tables to an ABAP/4 program.
advantages:-
The programmer need not worry about the primary key for each table.Because Logical database knows how the different tables relate to each other,and can issue the SELECT command with proper where clause to retrieve the data.
i)An easy-to-use standard user interface.
ii)check functions which check that user input is complete,correct,and plausible.
iii)meaningful data selection.
iv)central authorization checks for database accesses.
v)good read access performance while retaining the hierarchical data view determined by the application logic.
disadvantages:-
i)If you donot specify a logical database in the program attributes,the GET events never occur.
ii)There is no ENDGET command,so the code block associated with an event ends with the next event
statement (such as another GET or an END-OF-SELECTION).
1. transaction code SLDB.
2.enter name z<ldb-name>
3.create
4.short text
5.create
6. name of root node (here Ekko)
7. enter short text (f6)
8.node type -> data base table.
9.create
10 change logical DB
riht click on ekko and insert node
here node name ekpo
11.create
12. click on selections
13. press no Should the changed structure of Z<ldb name> be saved first.
14.select tables which you want to join.
15.transfer
16 now you have to o to coding part.
17. save
activate.
19.click to src code
double click on first include and activate

Query using logical database

Hi,
There is one query which is using logical database PNM. I have got one requirement to add one field in selection screen to filter the output. The field which is required to be displayed in selection screen to filter the data is from table mkal which is not present in logical database. Hence my question is, is it possible to add field from table which is not present in logical database? IF yes, please specify the procedure.

Hi Jogeswara,
Thanks for your inputs.
But my question is, how can I filter the data which is being fetched by standard logical database. I cannot go inside the std. LDB and change internal tables of it. I tried coding in extras, but I think it works only if we want to add additional fields in output.
At present, we are considering the option of creating a z LDB where we copy. std. LDB and also add the reqd. table which is not present in LDB.
Is there any other option?
Please provide your valuable inputs.
Regards,
Imran Kundan.

Can I use logical databases in a WebDynpro ABAP program?

can I use logical databases in a WebDynpro ABAP program?
I need to build a WDA screen that is similar to the SAPDBPNP selection screen (user can find the personnel number based on several criteria, such as last_name/first_name of the employee). So it seems that the existing logical databases have already many nice features already built (like the selection screens, the logic behind the screens etc). So I was wondering if/how I can use them in my WDA application.

Hello, Tiberiu.
You cannot use LDB directly within your WDA programa. BUT, you can fetch results from this LDB by using FM LDB_PROCESS. This function module can be called anytime from any kind of ABAP program. But you will still have to create the screen, as it only processes data, not screens.

Andre

Why u use logical databases

how u used logical database?how is data transferrd to program?corresponding statement in LDB?

Hi,
Logical databases are programs that does useful tasks like data fetch, Authorization check on behalf of thep program to which you attach them.
Some of the Tasks of LDB's.
Reading the same data for several programs.
The individual programs do not then need to know the exact structure of the relevant database tables (and especially not their foreign key relationships). Instead, they can rely on the logical database to read the database entries in the right order during the GET event.
Defining the same user interface for several programs.
Logical databases have a built-in selection screen. Therefore, all of the programs that use the logical database have the same user interface.
Central authorization checks
Authorization checks for central and sensitive data can be programmed centrally in the database to prevent them from being bypassed by simple application programs.
Improving Performance
If you want to improve response times, logical databases permit you to take a number of measures to achieve this (for example, using joins instead of nested SELECT statements). These become immediately effective in all of the application programs concerned and save you from having to modify their source code.
The data fetch happend with the PUT_XXXX subrotuines in the Logical database programs.
Example:
DATABASE PROGRAM OF THE LOGICAL DATABASE TEST_LDB
PROGRAM sapdbtest_ldb DEFINING DATABASE test_ldb.
TABLES: lfa1,
 lfb1,
 lfc1,
 bkpf.
Initialize selection screen (process before PBO)
FORM init.
ENDFORM. "INIT

How to use Logical database in function module?

I will create a function module in HR.
but how to use Logical database in function module ? Logical database PNP always show screen.in function (RFC) code , it is a matter.

You cannot attach the LDB to the main program of the function group.
- So you may [SUBMIT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=submit&adv=false&sortby=cm_rnd_rankvalue] a report which use the LDB and get back the data (export/import), by default in the syntax of SUBMIT the selection-screen will not be displayed
- Use [LDB_PROCESS|https://www.sdn.sap.com/irj/sdn/advancedsearch?query=ldb_process&cat=sdn_all], fill a structured table for selection, and get data back in another table
- Use [HR function modules to read Infotypes|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=hrfunctionmodulestoread+Infotypes&adv=false&sortby=cm_rnd_rankvalue].

How to inactivate the 'Complex Search' button when using Logical Database

Hy experts
I m using Logical Database for a select and you know that for an GET event by default in selection screen it appears some selection fields for every GET event..I manage to hide the ones that don't interest me but I have a little problem: I have a button that's called 'Complex Search' and I don't know how to get rid of this button..
Here is some code:
AT SELECTION-SCREEN OUTPUT.
LOOP AT SCREEN.
IF screen-name CP '%BT02010_BLOCK_1000'.
 screen-input = '0'.
 screen-active = 0.
 screen-invisible = 1.
 MODIFY SCREEN.
 ENDIF.
 IF screen-name CP 'QL_REFIL'.
 screen-input = '0'.
 screen-active = 0.
 screen-invisible = 1.
 MODIFY SCREEN.
 ENDIF.
I do this for every screen-name in the program that doesn t interes me..but it seams that even if I comment all the button with 'Complex Search' remains..I mention that is a disperate solution to inactivate every screen element but I could not do other way..My bigest pb is the 'Complex Seach' button..can anyone help me?? pls.. <REMOVED BY MODERATOR> ..thx..

Thank you Thomas,
I need some more from you...
If I have 8 tables for 8 columns, then how do i proceed?
Also could u tell me some query optimization techniques while working with intermedia text.
Thanks you once again,
waiting...
Khaleel Hi Khaleel,
I think this depends on your data model (relationship between the tables) and how you like to search later.
The optimization begins also with the create index statement (memory clause and storage clause).
If you like me to help I need more information about your hardware, os, datamodel and what kind of searches you will have later.
Cheers,
Thomas

Custom selection field using Logical database

Hi All,
I have to create a program that would print out employee contracts from infotype 16.
I am using logical database PNPCE.
Is there a way to add "contract type" as a selection parameter in the screen that is generated by PNPCE?
Thanks,
~Mark

Hi,
Create CTTYP(Contract type) as input parameter in the program.
Then after GET PERNR.
write check stmt for that field like below.
PARAMETERS: p_cttyp type p0016-cttyp.
GET PERNR.
CHECK p0016-cttyp EQ p_cttyp.

Splitting "pernrs" in program that is using logical database

Hello All,
I have a HR program that uploads data from file into infotype 377. Everything works fine except if the file has like 20000 records the program is taking for ever to run! I am using logical database (GET PERNR) in the program. I populate my pnpindex with all pernrs from file for processing. Is there any way I can aplit pernrs (like 5000 each processing) so that I can speed up the process i.e, I want to process 5000 pernrs at a time. I tried to find solution here but no luck and I am out of ideas. If you happen to have any ideas on this, please let me know.
Thanks.

Radio Button problem when using Logical Databases.

Hi,
I have a report that uses logical database PCH. I'd like to default the reporting period radio button so that when the report is run it is defaulted to today.
The name of the screenfield is PCHZTR_D so I set
PCHZTR_D = 'X'.
in the initialisation event but this doesn't work.
Any suggestions how I can get the reporting period to default to 'today' programmatically.
I don't want to use a variant.
Thanks,
Paul

Try doing it in the AT SELECTION-SCREEN output Event.
report zrich_0001.
nodes: objec.
at selection-screen output.
PCHZTR_A = space.
PCHZTR_D = 'X'.
