Regarding Logical Database

Hi all,
      My problem is transporting Logical Database to Production server. first i have transported to quality server. in Quality Server it is working fine. But when i Transport to Production , 'Documentation Not exist ' erro r is coming.
        But i already create Documentation for logical database using se36.
       Is there any other reasons for not transporting to Production server.
Thanks,

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.

Regarding logical database PSJ

Hi,
how can we add a additional field (Activity type )to the logical database PSJ used for transaction CN47N.The field does not exist in the given field options
My requirement is currently the program RPSISVG000 display the actual hours of the activity without any filter on the activity type. user requirement is to filter the data based on few activity types given by them. ie they want the actual hours to be calculated only for these activity types.
CN47N transaction has been customized to ZCN47N.
I have populated a field with given activity types but could not get the point where to do the filteration as the program uses GET events.
GET ACT01. (contains the field activity type LARNT)
Please let me know how to filter the data based on the activity types.
Thanks and Regards,

    Originally, there are some buttons like 'Further selection' 'selection helps ' 'Sort order' at the top of selection screen. How could I control them? If I just use some of them , like 'Further selection' , How could I remove the other two from the selection screen ?
     what's more, How could I add button like 'Org. struture' at the top which doesn't exsit originally?
Thank you very much!

Query regarding Logical Database reports

Hi,
I have started doing pgm on Logical Database report using VBAK,VBAP and MARA. I took VBAK as the root node and VBAP& MARA as subnodes. The actual requirement is:- I am trying to place these tables in Application server for perfromance issue using Logical database. Based on sales, the items need to be be displayed. And based on Items, the material data should be displayed.So root node here is VBAK.
I have created these 3 nodes in SE36 tx.code. when I go back to se36 main screen and under "subobjects" ,I've selected "selections". I got a dialog box saying that "Nodes for which free selections are to be made". I have clicked on the radio buttons.And then clicked on "transfer" . I am getting a runtime error . Please let me know the solution.
Please do send me the actual process to go on with logical database reporting.

Hi,
I have selected the logical dtaabase pnp in my attributs screen.
i have read that logical databases can have a maximum of 300 tables.
So what tables can i access using the pnp LDB.
Also i have heard that if we select a LDB a standard selection screen appears.
But in my case it does not appear.
Please help.

Logical Database PGQ structure usage

Hello Everyone,
I have a question regarding Logical Database(LDB) usage...How to use the structure defined in LDB. We are using PGQ Logical database in one of custom programs. The structure of the LDB as hierarchy or tree is:
QALS
      QAVE
      QMFEL
      QAPO
           AFFHD
           QAMV
                QAMR
                     QASE ---> From this table
                QASV
                     QASR ---> From this table
and etc
The code was something like this in the program:
GET QALS.
GET QAPO.
GET QAMV.
GET QAMR.
Now, my requirement is to get data additionally from QASE and QASR tables..So, I tried modifying the code according to the hierarchy structure defined in the PGQ LDB(check bold statements):
GET QALS.
GET QAPO.
GET QAMV.
GET QAMR.
<b>GET QASE.
GET QASV.
GET QASR.</b>
But in runtime I see that QAMR and QASE is filled up with # data ...I am not sure if is right way to do....Is this the way to use the structure defined in the Logical database? QAMV and QASV lie in the same level of hierarchy and I have to use them to get QASE and QASR data...Let me know, if I am not clear...
Thanks for taking your time and I appreciate if some one can help me.

Hi Ankur
You can use program SAPDBPGQ that is program created to test logical database PGQ. Then you can get only part responsible for nodes QALS, QAPO and QAMV

Regarding Query and Logical database

Hi All,
I have one requirement to create a report which gives all selection fields of a query.I got the selection fields defined in the query,but some extra selection fields are coming from logical database,which query uses.These extra fields count is different for different queries using same logical data base.Please suggest me a solution.

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.

Logical Database in Abap Objects

Hi to All
I want do it a program report using a Logical Database.
Is this possible ??? But when I make a GET <node>, occurs the following error:
         "" Statement "ENDMETHOD" missing. ""
I'm doing the following:
CLASS MONFIN IMPLEMENTATION.
       METHOD TRAER_DATOS.
               GET VBRK.
       ENDMETHOD.
ENDCLASS.
Please, somebody tell me how I use the logical database in Abap Objects.
Thank you very much
Regards
Dario R.

Hi there
Logical databases whilst of "some use" are not really part of OO.
If you want to use a logical database in an abap OO program I would create a special class which just does the get data from your DB and pass this either at record or table level.
Techniques such as GET XXXX LATE aren't really part of any OO type of application since at Object Instantiation time you should be able to access ALL the attributes of that object.
As far as OO is concerned Logical databases are a throwback to "Dinosaur Technology".
Since however modules such as SD and FI are still heavily reliant on relational structures (i.e linked tables etc) then there is still some limited life in this stuff but for OO try and solve it by another method.
If you really must use this stuff in OO then do it via a FMOD call and save the data in a table which your method will pass back to your application program.
You can't issue a GET command directly in a method.
Cheers
Jimbo

Logical database in adhoc query

Hello All,
Can anyone tell me what is the logical database in adhoc query?

Hi
When you create a query , you have to select an infoset. Infoset can be considered as a source from which data is populated in the Query Fields.
Infosets are created from Transaction SQ02.
There can be four methods through which an Infoset can become a source of data:
1. Table join ( By joining two or more tables from Data dictionary)
example: Joining tables PA0001 and PA0006 on Pernr to get a one resultant dataset
2. Direct read of Basis Table ( Like PA0001 as a source for data in Infoset )
3. Logical Database ( A Pre-written Program by SAP that extract data from clusters, tables taking care of authorizations and validity periods)
Example : Logical database PNP, PNPCE (Concurrent Employement),PCH ( LDB for Personnel Development Data)
Custom Logical DBs can be created in T_Code SE-36.
4. Data Retrieval by a Program ( Custom code written by ABAP developers which will collect and process data) . This program has a corresponding Structure in data dictionary and the fields of this structure will be used in query)
Reward Points, if helpful.

LOGICAL DATABASE IN HR ABAP PRPGRAMMING

Hi Friends,
what is use of LOGICAL DATABASE IN HR ABAP PROGRAMMING
AND END-OF-SELECTION EVENT IN HR PROGRAMMING PROGRAMMING???
regards,
vijay.

hi
HR Logical Databases
In Human Resources (HR), the following logical databases can be used as a data source for HR InfoSets:
PNP (PNPCE)
PAP
PCH
By selecting a logical database, you determine the HR data that can be reported on using an InfoSet.
Logical Database PCH
This logical database generally enables you to report on all HR infotypes. However, you are advised not to use this logical database unless you want to report on Personnel Planning data.
Logical Database PNP (or PNPCE)
Use logical database PNP to report on HR master data. It is possible to use logical database PCH to access this data, but PNP meets such reporting requirements more quickly because it is best suited to the task of selecting persons.
Logical database PNP enables you to access HR master data and infotypes from Personnel Planning. For example, you have the following options:
Reporting on the costs, number of attendees booked, and instructor for a business event on which an employee is booked
Reporting on working time and planned compensation for a position that an employee occupies
Reporting on the validity and proficiency of a qualification that an employee fulfils
From a technical perspective, this means you can use PNP to report on all of the infotypes that exist for objects (infotype 1000) that have a direct relationship (infotype 1001) with the Person object.
The ability to access infotypes from Personnel Planning using logical database PNP is a special feature that you can only use in the context of SAP Query and Ad Hoc Query. You cannot use this functionality for ABAP reports you programmed yourself.
You can also use logical database PNP to report on data from Personnel Time Management (infotypes 2000 to 2999) and Payroll (special payroll infotypes for the USA and customer infotypes; for more information, access Customizing for the Human Resources Information System and see Payroll Results).
Logical Database PAP
Logical database PAP enables you to access data from Recruitment.
