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.

How to save a variant with dynamic selections parameters

Anybody knows how to save a variant for an ABAP that uses a Logical database with Dynamic Selections?
Have a look for example to the following:
SE38 - DEMO_PROGRAM_GET - Execute - Shift F4 - Connection Number.
How to save 0820 as Connection Number?
Function Group SVAR seems good but FREE SELECTIONs are not easy to manage...

Hello,
I tried to save the variant of DEMO_PROGRAM_GET with dynamic selection field (Connection Number) filled. It gets saved without any problem. Just click 'SAVE' and enter the variant name and description.
Thanks,
Venu

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 call logical database

hi friends,
plz explain me how to call logical database in a report program?

hi,
Logical databases are special ABAP programs that retrieve data and make it available to application programs. The most common use of logical databases is still to read data from database tables by linking them to executable ABAP programs.
However, from Release 4.5A, it has also been possible to call logical databases using the function module LDB_PROCESS. This allows you to call several logical databases from any ABAP program, nested in any way. It is also possible to call a logical database more than once in a program, if it has been programmed to allow this. This is particularly useful for programs with type 1.
Logical databases contain Open SQL statements that read data from the database. You do not therefore need to use SQL in your own programs. The logical database reads the program, stores them in the program if necessary, and then passes them line by line to the application program or the function module LDB_PROCESS using an interface work area.
Logical Databases - Views of Data
A logical database provides a particular view of database tables in the R/3 System. It is always worth using logical databases if the structure of the data that you want to read corresponds to a view available through a logical database.
The data structure in a logical database is hierarchical. Many tables in the R/3 System are linked to each other using foreign key relationships. Some of these dependencies form tree-like hierarchical structures. Logical databases read data from database tables that are part of these structures.
Advantages of Logical database -
1) No need of programming for retrieval , meaning for data selection
2) Easy to use standard user interface, have check completeness of user input.
Disadvantages
1) Fast in case of lesser no. of tables But if the table is in the lowest level of hierarchy, all upper level tables should be read so performance is slower.

Why and how we use Logical Database?

Can anybody explain with example why and how we use logical database?
Regards,
Rajan

Hello,
SAP comes loaded with all the extras. Among the extras that are most helpful to IT managers are all the access routines needed to pull any business object that managers can think of out of SAP databases. However, SAP has not thought of everything where your particular applications are concerned. SAP organizes its standard database tables to service business units based on conventional business applications. Itu2019s likely your business requires something new, perhaps even something exotic. In that case, you will need to create a new database, using information from different places. Basically, you need a logical database. You need to create a virtual business data object repository consisting of a new kind of record or table that suits your purposes. In addition, the repository should be composed of information that is actually stored in a number of different locations, none of them necessarily logically associated with one another. Letu2019s take a closer look at creating logical databases.
A case for a logical database
Suppose my company manufactures widgets of the most obscure variety, and they are components of other widgets. I sell my widgets as raw material for the more sophisticated widgets built by others, but in some cases I actually partner with other manufacturers in creating yet another class of widget. Now, in my world, I consequently have customers who are also partners. I sell to them and I partner with them in manufacturing and distribution. Also, I need an application that uses both of these dual-use relationships.
Essentially, I have a customer database and a partner database. Neither contains records that are structured to contain the identifying particulars of the other. Thus, I need a hybrid database that gives me tables detailing these hybrid relationships. What can I do? I can go the long way around and write a new database, pulling information from both and creating new objects with a customized program that I write by hand. However, this process is cumbersome and contains maintenance issues. On the other hand, I can use SAPu2019s logical database facility, create my logical database in a couple of minutes, and have no maintenance issues at all.
Logical database structures
There are three defining entities in an SAP logical database. You must be clear on all three in order to create and use one.
u2022     Table structure: Your logical database includes data from specified tables in SAP. There is a hierarchy among these tables defined by their foreign keys (all known to SAP), and you are going to define a customized relationship between select tables. This structure is unique and must be defined and saved.
u2022     Data selection: You may not want or need every item in the referenced tables that contributes to your customized database. There is a selection screen that permits you to pick and choose.
u2022     Database access programming: Once youu2019ve defined your logical database, SAP will generate the access subroutines needed to pull the data in the way you want it pulled.
Creating your own logical database
ABAP/4 (Advanced Business Application Programming language, version 4) is the language created by SAP for implementation and customization of its R/3 system. ABAP/4 comes loaded with many predefined logical databases that can construct and table just about any conventional business objects you might need in any canned SAP application. However, you can also create your own logical databases to construct any custom objects you care to define, as your application requires in ABAP/4. Hereu2019s a step-by-step guide:
1.     Call up transaction SLDB (or transaction SE36). The path you want is Tools | ABAP Workbench | Development | Programming Environment | Logical Databases. This screen is called Logical Database Builder.
2.     Enter an appropriate name in the logical database name field. You have three options on this screen: Create, Display, and Change. Choose Create.
3.     Youu2019ll be prompted for a short text description of your new logical database. Enter one. Youu2019ll then be prompted to specify a development class.
4.     Now comes the fun part! You must specify a root node, or a parent table, as the basis of your logical database structure. You can now place subsequent tables under the root table as needed to assemble the data object you want. You can access this tree from this point forward, to add additional tables, by selecting that root node and following the path Edit | Node | Create. Once youu2019ve saved the structure you define in this step, the system will generate the programming necessary to access your logical database. The best part is you donu2019t have to write a single line of code.

How to know whether database(oracle) is up and running at OS level

how to know whether database(oracle) is up and running at OS level...!!!

depends on the O/S you are using, Unix or Windows? I would use Korn shell script to monitor the Oracle background process and scripts to check of Oracle is accepting connections.
This UNIX command will show the number of processes for your instance:
ps -ef|grep $ORACLE_SID|grep -v grep|grep -v ora_|wc u2013l
In Windows I would look into services.msc

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.

Logical database and program selection filter

Hi experts ,
In my program i have to select pernr through logical database selection and payroll area through manual coding .
Could you tell me how to give the filter condition in program.I am using PNPCE Logical database .
Thank you.
Devika.

I guess you mean to modify the screen layout during AT SELECTION-SCREEN OUTPUT via
AT SELECTION-SCREEN OUTPUT.
LOOP AT SCREEN.
screen-active = 0.
MODIFY SCREEN.
ENDLOOP.
This does hides all screen elements but the screen is still displayed.
