Logical database PCH,Extended Object ID

When using logical database PCH.I found Object structure has a component REALO means extended object id.
Can somebody give a example to show the actual meaning of extended object id?
thanks.

Issues with parallel processing in Logical Database PCH and PNP

Has anyone encountered issues when executing programs in parallel that utilizes the logical database PCH or PNP?
Our scenario is the following:
We having have 55 concurrent jobs that execute a program that use the logical database PCH at a given time. We load the the PCHINDEX table with the code below.
      wa_pchindex-plvar = '01'.
      wa_pchindex-otype = 'S'.
      wa_pchindex-objid_low = index_objid.
      APPEND wa_pchindex TO pchindex.
We have seen instances where when the program is executed in parallel, with each process having its own range of positions id's, that some positions are dropped or some are added that is outside the range of the given process.
For example:
process 1 has a range of positions ID's 1-10
process 2 has a range of positions ID's 11-20
process 3 has a range of positions ID's 21-30
Process 3 drops position 25 and adds position 46.
Has anyone faced a similar issue?
Thanks for your help.

Hi,
first of all, you should read [Using Parallel Execution|http://download.oracle.com/docs/cd/B19306_01/server.102/b14223/usingpe.htm#DWHSG024] in documentation for your version - almost all of these topics are covered there.
1. According to my server specification how much DOP i can specify.It depends not only on number of CPU. More important factors are settings of PARALLEL_MAX_SERVERS and PARALLEL_ADAPTIVE_MULTI_USER.
2. Which option for Setting Parallel is good - Using the 'alter table A parallel 4' or passing the parallel hints in the sql statementsIt depends on your application. When setting PARALLEL on a table, all SQL dealing with that table would be considered for parallel execution. So if it is normal for your app to use parallel access to that table, it's OK. If you want to use PX on a limited set of SQL, then hints or session settings are more appropriate.
3. We have a batch processing jobs which are loading data into the tables from flat files (24*7) using sql loader. is it possible to parallel this operation and any negative effect if enabled parallel.Yes, refer to documentation.
4. Query or DML - which one will be perform best with parallel option.Both may take advantages of using PX (with some restrictions to Parallel DML) and both may run slower than non-PX versions.
5. What are the negative issue if parallel option is enabled.1) Object checkpoint happens before starting parallel FTS (true for >=10gR2, before that version tablespace checkpoint was used)
2) More CPU and memory resources are used with PX - it may be both benefit and an issue, especially with concurrent PX.
6. what are the things to be taken care while enabling the parallel option.Read the documentation - it contains almost all you need to know. Since you are using RAC, you sould not forget about method of PX slaves load balancing between nodes. If you are on 10g, refer to INSTANSE_GROUPS/PARALLEL_INSTANCE_GROUPS parameters, if you are using 11g then properly configure services.

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

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

Selection screen of logical database PCH

Hi all,
I am writing a report using the logical database PCH. For this report I need the full selection screen of the logical database, especially the structure parameters. However, wenn I test my program, I only get a reduced selection screen without the structure parameters and the "further conditions". According to the documentation I found, this behaviour appears when you set the selection screen version to '900' in the program attributes. In my program, the selection screen version is empty, and I still get the reduced screen. The missing selection fields are even totally unknown to the ABAP compiler. E.g. when I try to assign the field PCHWEGID in my report, I get a "field unknown" error message from the compiler.
I have compared my report in various aspects to the standard report RHSTRU00 which shows the behaviour I want, I did not find any difference, and yet I get a different behaviour.
Any ideas how to fix this?
Thank you

Selection-screen logical database PCH

Hello!!
   I need click a pushbutton (key date) on a selection screen of a logical database (PCH) before the programm is executed.
Regards.

For a ABAP I used this "quick and dirty" solution:
*Add selectoption (or in your case button)
SELECT-OPTIONS s_ssl FOR iooper-ssavd.
INITIALIZATION.
perform hide_selection_screen.
AT SELECTION-SCREEN output.
perform hide_selection_screen.
FORM perform hide_selection_screen.
LOOP AT SCREEN.
    IF screen-name CS 'S_WERK'.
      MOVE '0' TO screen-active.
      MODIFY SCREEN.
    ENDIF.
ENDLOOP.
ENDFORM perform hide_selection_screen.
You can hide all required radiobuttons by adding them to the loop. The buttonclick can be catched at the previous mentioned event.

Do we have macros which we can use for the Logical Database PCH

Dear Friends
I would like to know when we are using the
Logical Database PCH .....do we have any macros
for getting latest record etc.
i.e i mean to say the macros which we use
Rp-provide-from-last in PNP logical Database
do we have same facility in PCH logical database please let me know
regards
madhuri.

hi madhuri,
we use same macro.
instead of get pernr .
in pnp here we give
GET OBJEC.
use this macro
PAP_PROVIDE_FROM_FIRST P0001 SPACE PA$BEGDA PA$ENDDA
PAP_PROVIDE_FROM_LAST P0001 SPACE PA$BEGDA PA$ENDDA.

Difference between PNP and PCH logical database

WHats the difference between PNP nd PCH? When to use which??
Tx

Hi,
The Difference is only with in an SAP R/3 system in which Concurrent Employment is active, reports are executed by the PNPCE logical database. The general logic of the PNPCE logical database corresponds to the PNP logical database. The PNPCE logical database can also process the concept of Concurrent Employment.
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.

Database PCH

Hi Experts,
with the following macros I can restrict the results on the database PCH.
TABLES: objec.
START-OF-SELECTION.
RH-SET-INDEX-INFTY '1007'.
RH-CONDITION-LINE VACAN EQ 'X' SPACE.
RH-SET-INDEX-INFTY-CONDITION.
GET objec.
Is it possible to repeat the macro RH-CONDITION-LINE? I tried to do it that way and only the last line condition seems to be executed.
Is there a documentation regarding the macros for the database PCH?
Any Helpfull answer?
thanks...

FYI
Logical database PCH is large and can take a while to run.
To improve performance it is possible to restrict the hit on the database by filtering on any field,
for example when retrieving records from infotype P1007 (vacancy) for current vacancies you can
include the following code before the get statement:-
CONSTANTS: $1007 LIKE P1007-INFTY VALUE '1007'.
START-OF-SELECTION.
RH-SET-INDEX-INFTY $1007.
RH-CONDITION-LINE VACAN EQ 'X' SPACE.
RH-SET-INDEX-INFTY-CONDITION.
GET objec.
This will retrieve only those records from the logical database where the field p1007-vacan = 'X', otherwise you would need to retrieve all records first and then filter on p1007-vacan (where vacan = 'X')
Cant explain this code as cant find any documentation on it but it is used in SAP standard.
The call sequence of PCH macros facilitates fast object selection using value conditions of infotype fields (infotype index). You must use this call sequence when objects are
selected for sequential evaluations on the basis of whether infotypes exist with specific field values, rather than using the object ID.
The RH-SET-INDEX-INFTY macro specifies the infotype to be indexed.
The parameters of the RH-CONDITION-LINE macro are:
Parameter 1 : Field name (for example, ABTEL)
Parameter 2 : Condition (for example, EQ, BT)
Parameter 3 : Value (for example, "X")
Parameter 4 : Value (for Between)
The RH-SET-INDEX-INFTY-CONDITION macro is used to set the condition as an index.
You can use this method for sequential evaluations, but not for structural evaluations

Logical Database

Hi,
I have the following issue:
we need to make use of BADI 'MD_PURREQ_CHANGE' here I need to use Logical Database 'DBM' in my implimentation method. Shall we make use of Logical Databse in ABAP Objects? If yes, could you give any ideas please?
Thanks & regards
Sreenivas

Hi,
I tried several times, it seems that is not possible to make use of Logical Database from ABAP Objects.
IS there any ideas?
I am providing some more details:
While I was testing the MRP BADI the MDTB table is not being updated with any data . OSS note 440016 says that there is a customizing setting by which you can still update the MDTB table but this would lead to performance issues (easier to query though).
In standard SAP, MRP data is stored as an aggregated list (table is stored as a data cluster and I need an ABAP extract to get something meaningful from it) in table MDTC for improved performance.
Does any body having an ideas on this?
Thanks & regards

Steps to create LOGICAL DATABASE in sap

hi guys,
i have gone through many documents about LDB. But, i didnt get the steps to create a LDB.
plz provide me with the steps to be followed to create a LDB.
thnx,
shivaa.

Hi Shiva,
This might help you!
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.
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.
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.
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 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
