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.

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: 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

Logical Database and Logical Thing

Hi,
i want to access KONV which is cluster table and the field is KWERT.
The thing is that i want to access it by taking customers from KNVV and giving it to VBRK (SALES Table). Now in VBRK i want to have a selection on FKDAT to get a list of Customers stored in the field called KUNAG.
on VBRK-KUNAG basis i want to access the table KONV-KWERT.
If i am doing queries then the System stops responding cuz it has got alot of overhead. So i tried to use Logical Database called VFV.
If this is the best solution means using LDB then how to use it, can anyone help me with this. I tried it by Function module but it is showing all data without considering selection criteria.
If anyone can help me then plz do answer or refer me to any web site so that i can figure this thing out. If anyione has got a good book on that then plz feel free to mail me.
Thanks,

Thanks Shibba that was very helpful, i applied that but the system overhead was so much.
can u help me with Dynamic selection code.
I used FREE_SELECTION_INIT, FREE_SELECTION_DIALOG and then FREE_SELECTIONS_RANGE_2_WHERE to get ther Selections in one table.
if u want me to send u the code then i can do that cuz i am getting so much mad that this work is not done yet.
The Scenario here is that we want to take BILLED Customers and VKORG as Industrial Billing Customer and then taking VBRK and giving all these Customers and then taking selection on FKDAT range.
Now after that the data should be collected from KONV-KWERT and i want to perform some calculation over it. I am using VFV (Logical Database) to perform this thing because i know that it would be very fast then applying my own queries.
If you can mail me any book on Logical Database and Dynamic selection then it will be very Helpful.
Thanks once again for being such helpful.

Regarding Logical database and select statement..

Hi
Experts.
i would like to know the diff b/w logical data base & select statement while using report.
wt is the use of logical databases in R/3. is there   any   advantage used in the reports.
Thanks & Regards..
Spandana.

Dear Spandana,
Go through the below description of LDB. I hope you wil get a fair amount of idea.
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.
Watch out!
The use of very large tables will degrade the performance of a logical database, so be aware of that trade-off. Remember that some tables in SAP are very complex, so they will be problematic in any user-defined logical database.
Declaring a logical database
Hereu2019s another surprising feature of logical databases: You do not assign them in your ABAP/4 Code. Instead, the system requires that you specify logical databases as attributes. So when you are creating a report, have your logical database identifier (the name you gave it) on hand when you are defining its attributes on the Program Attributes screen. The Attributes section of the screen (the lower half) will include a Logical database field, where you can declare your logical database.
Logical databases for increasing efficiency
Why else would you want to create a logical database? Consider that the logical databases already available to you begin with a root node and proceed downward from there. If the data object you wish to construct consists of items that are all below the root node, you can use an existing logical database program to extract the data, then trim away what you donu2019t want using SELECT statementsu2014or you can increase the speed of the logical database program considerably by redefining the logical database for your object and starting with a table down in the chain. Either way, youu2019ll eliminate a great deal of overhead.

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.

Using Logical Databases and the Tables or Nodes Statement

I want to start using Logical Databases whenever possible, but it seems that I need to use the Tables or Nodes statement for the Get statement to work. Is there anyway to avoid Tables/Nodes statement since they are obsolete (and still use LDBs)?
Message was edited by: Jason DeLuca

Hi Jason,
1) table statement is obligatory:
-> look at abap-docu to GET:
node is a node in the logical database that is assigned to the report (type 1 program) in the program attributes. <b>You must declare the node in the report using the NODES statement (or the TABLES statement, if the node is of the type "table").</b>
2) some ldb-selections from the selection screen
depends on the table-statement too, i remember...

What exactly are Logical Database in Programs?

Hi Experts,
While digging deep into the programs, using the T-Code SE93/SE38, we come across Logical Database.
what is the functionality and use of this Logical Database?
Best Regards,

Normally moderators reject unresearched questions, but this one has not been discussed much for it's security aspects.
In the ABAP forums you will find a lot of discussions about LDB's ("LDB" is your search term).
Please do a search and reconsider and focus your question more.
What is it about LDB's that you would like to discuss?

Infoset query logical database and transparent table

Hi!
We have an infoset with the data source logical database=PNP.
We get some fields from the infotype 0768, P0768-PERNR, P0768-BEGDA, etc.
Now we need add another table to make a join within infotype 0768 and table T5F99SE.
For instance, in infotype 0768 I have one record with the fields PERNR and BEGDA and in the T5F99SE I have 3 records related to the unique record of infotype 0768, the fields of the table are PERNR, BEGDA, ACTDT and ADDAT .
The fields values in the example can be:
Infotype 0768: PERNR=00101800, BEGDA=20110401, DICOT=20, BACHE=1200
Table T5F99SE: record 1 PERNR=00101800, BEGDA=20110401, ACTDT=20110401, ADDAT=PB    E
                         record 2 PERNR=00101800, BEGDA=20110101, ACTDT=20110405, ADDAT=PC    E01
                         record 3 PERNR=00101800, BEGDA=20110401, ACTDT=20110409, ADDAT=PA    E
The result we want get with infoset query is
PERNR    BEGDA   DICOT BACHE   ADDAT
00101800 20110101 20        1200       PB    E
00101800 20110101 20        1200       PC    E01
00101800 20110101 20        1200       PA    E
I would like to get the fields of the infotype and some fields of the table T5F99SE.
Is possible do this action with ABAP modifying an infoset that already exists adding the fields of the transparent table?
What should I do?
Kind regards,
Julian.

My guess is that it would not be possible to include a transparent table into the LDBs PNP and PNPCE. Would need input from a technical expert there.
However, instead of using the LDB, why don't you explore just using a direct table join? You may need to join PA0000, PA0001, PA0002 along with PA0768 and your other tables. An infoset can then be created on this table join.
To go to the mode where you can create the table join, in your infoset transactions, choose 'Table join' instead of 'LDB'.

Submit to report with logical DB and Dynamic selection

Hi.
Is there an option to pass parameters to the dynamic fields of the LDB?
The command 'SUBMIT' can only allow me to pass params to the static selection screen.
Thanks

Hi Ariel
Actually SUBMIT will only accept fields that are described in the target program indeed.
For this case you can use SET PARAMETERS to send values from initial program to dynamic field

Customize selection screen of logical database AFI of report RIAUFK20 ?

Hi Experts,
I have to customize the report RIAUFK20 which use logical database AFI.
I have to do the following:
- Change the field labels of some fields in the selection screen.
- Add more field into selection screen which does not appear in the nodes of logical database structure, for example TIDNR in table EQUZ.
So what is the best way to achieve that result?
I intended to copy the AFI into ZAFI and change, but still struggle with add fields which does not appear in the structure of logical database.
Any help is appreciated, thanks!

Specify your logical database on Program "attributes".
It will display the standard selection screen of LDB. Now in your report, create selection screen as in other programs for the additional fields.
It will first display the field of LDB, followed by fields provided by your selection screen.
