Timestamp in cluster tables

Why do we use the field TIMESTAMP in cluster tbles.
Please explain....
Thanks..

Hi ,
Go through the below data .
Working with Timestamp
An extension of the DATE data type that can store date and time data (including fractional seconds).
The ABAP Dictionary contains the data elements TIMESTAMP, TIMESTAMPL,
TIMESTAMP = P(8) Decimal 0
TIMESTAMPL = P(11) Decimal 7 ( decimal for fraction of second)
Commands
GET TIME: Places the current time in the system field SY-UZEIT. At the same time, SY-DATUM is set, and the system fields for the local time zone (SY-TIMLO,SY-DATLO, and SY-ZONLO) are refreshed.
GET TIME STAMP FIELD <F> Returns the timestamp in short or long form. The short form contains the current date and time; the long form also contains seven decimal places for fractions of a second, making the timestamp accurate to within 100 nanoseconds.
*--To get the Current Date/Timestamp
get time stamp field v_gv_curr_timest.
Hope it helps you.

Anusha V

How to extract data from cluster table

Hi, experts,
Here I want to extract change documents, which is from tables CDHDR(header) and CDPOS(line items). The problem is that CDPOS is a cluster table so that I can't create a view to develop a generic data source.
I have search on the forum and some one said generic data source based on function module was a choice, but I think coding FM is so complex, especially including delta implementation.
Could any one give me some advice? or give me some coding samples?
Thanks a lot!

Dear Sam,
I would suggest you to have a look at the function module CHANGEDOCUMENT_READ u2013 you can use this function module as a core in the developed function module for generic extractor. Unfortunately, the suggested function module can not handle import parameters for field names, so the strategy which can be applied here is to use this function module to fill the internal table based on restrictions on object class and table name and then go through filled internal table and delete records which are not relevant for fields KOFIZ or ABRSPERR.
As for delta implementation, would you please advise if delta relevant field based on timestamp generated on date and time of the change document is sufficient for your needs? If so then you can use fields UDATE and UTIME to generate timestamp on them including the field containing generated timestamp to the extract table. Next step here is to choose this field as delta relevant field in the Generic DataSource maintenance (TCode RSO2).
Please inform me if this solution suits you or if you have any questions or concerns regarding it.
My best regards,
Vadim

POOL & CLUSTER TABLEs

Hi Experts,
Can you send me some example tables for pool and cluster tables..
And where exactly you use these tables in real time..
Kindly reply me as early as possible
Thanks in advance
Santosh

Hi santosh,
Go to se11
table DD02L-> Give TABCLASS as POOL or CLUSTER you will get a list of tables
Pooled and Cluster Tables
Table pools (pools) and table clusters (clusters) are special table types in the ABAP Dictionary. The data from several different tables can be stored together in a table pool or table cluster. Tables assigned to a table pool or table cluster are referred to as pooled tables or cluster tables.
A table pool or table cluster should be used exclusively for storing internal control information (screen sequences, program parameters, temporary data, continuous texts such as documentation). Data of commercial relevance is usually stored in transparent tables.
Table Pools
A table in the database in which all records from the pooled tables assigned to the table pool are stored corresponds to a table pool.
The definition of a pool consists essentially of two key fields (Tabname and Varkey) and a long argument field (Vardata). A pool has the following structure:
Field
Data type
Meaning
Tabname
CHAR(10)
Name of pooled table
Varkey
CHAR (n)
Contains the entries from all key fields of the pooled table record as a string, max. length for n is 110
Dataln
INT2(5)
Length of the string in Vardata
Vardata
RAW (n)
Contains the entries from all data fields of the pooled table record as a string, max. length n depends on the database system used
If a pooled table record is saved, it is stored in the table pool assigned. The name of the pooled table is written to the field Tabname. The contents of all key fields of the pooled table are written as a string to field Varkey and the contents of all data fields as a string to field Vardata. The length of the string stored in Vardata is entered in field Dataln by the database interface.
Due to the structure of a table pool, there are certain restrictions on the pooled tables assigned to it. The name of a pooled table may not exceed 10 characters. Since Varkey is a character field, all key fields of a pooled table must have character data types (for example, CHAR, NUMC, CLNT). The total length of all key fields or all data fields of a pooled table must not exceed the length of the Varkey or Vardata field of the assigned pool.
Table Clusters
Several logical data records from different cluster tables can be stored together in one physical record in a table cluster.
A cluster key consists of a series of freely definable key fields and a field (Pageno) for distinguishing continuation records. A cluster also contains a long field (Vardata) that contains the contents of the data fields of the cluster tables for this key. If the data does not fit into the long field, continuation records are created. Control information on the structure of the data string is still written at the beginning of the Vardata field. A table cluster has the following structure:
Field
Data type
Meaning
CLKEY1
First key field
CLKEY2
Second key field
CLKEYn
nth key field
Pageno
INT2(5)
Number of the continuation record
Timestamp
CHAR(14)
Time stamps
Pagelg
INT2(5)
Length of the string in Vardata
Vardata
RAW (n)
Contains the entries from the data fields of the assigned cluster tables as a string, max. length n depends on the database system used
The records of all cluster tables with the same key are stored under one key in the assigned table cluster. The values of the key fields are stored in the corresponding key fields of the table cluster. The values of all data fields of the assigned cluster tables are written as a string to the Vardata field of the table cluster. Besides the actual data values, the data string contains information on the structure of the data and which table it comes from. If the string exceeds the maximum length of the Vardata field, a continuation record is written with the same key values. The continuation records for a key are distinguished by their value in field Pageno. The actual length of the string in the Vardata field is stored in the Pagelg field by the database interface.
You need the structural information stored in the ABAP Dictionary to read the data from a pooled table or cluster table correctly. These tables can therefore only be processed using Open SQL with the cluster interface, and not with Native SQL directly in the database.
In Repository informatino SE84 goto ABAP Dictonary -> Other Objects -> Pooled and clustered tables -> And then execute. It will give the list of available pooled/clustered tables.

Techniques for accessing CLUSTER tables

Can some 1 plz tell me , How many standard methods are there to access a cluster table. I want to know each and every method with example.1 method is Logical databases , 2nd is thrugh se16. But I want to know each and every.
My cluster tables are
1) ZNO_CT1 having fields (mandt , roll_no , Name)
2) ZNO_CT2 having fields (mandt , roll_no , Age)
AND these are assigned to the table cluster 'ZNO_CLUST'.
ZNO_CLUST has (mandt , roll_no , pageno , timestamp , VARDATA)

Hi,
You can find the methods below.
Just go thru this link-
http://dev.mysql.com/doc/ndbapi/en/class-table.html
Thanks

Where we can use pooled and cluster tables.

Hi Experts,
I have read all the threads and tutorials. all are telling like the difference between pooled and clulster tables are
Pooled table
It can hold small amount of data ( 10 to 100 records) and large number of tables( 100 to 1000 tables). It has fixed structure like Tabname, Varkey, Datain, Vardata.
Cluter tables
It can hold large amount of data but small number of tables. It is also have fixed strucuter like CLKEY1,CLKEY2 , CLKEY3...., Pageno, Timestamp, Pagelg, Vardata.
But i want which situation we can choose pooled table and which situation we can choose cluster table. In general way or Business way.
Thank you,
Srinivas M

Let me correct you, the data is not stored in alphanumeric but in RAW format in pool & cluster tables.
SAP says pool & cluster tables are created so that data from different tables belonging containing similar kind of data are clubbed together. I am not sure if storing data in RAW format compresses its size but SAP recommends storing business data in transperant tables.
Quote from SAP documentation:
"Data of commercial relevance is usually stored in transparent tables."
If data compression were a significant point SAP would have stored data in table clusters & not in transperant tables.
Comments are welcome.

How to get the data from a cluster table to BW

Dear All,
I want to extract the data from R/3 to BW by using 2 tables and one Cluster B2.
Actually my report contains some fields from PA2001, PA2002 and one cluster table B2 (Table ZES). Can I create View by using these 3 tables? If it is not possible how can I get the data from the cluster? Can I create generic datasource by using cluster tables directly?
In SE11 Transaction the Cluster (table ZES) is showing invalid table.
I referred some Forums, but no use.
Can any body tell me procedure to get the data from a cluster (table ZES) ?
Waiting for you results.
Thanks and regards
Rajesh

HI Siggi,
Thank you for your reply..
I am also planning to do FM to get the data. But it is saying that the Cluster table ZES does not exist (ZES is the the standard table, in SE11 also).
How can I use the Fields from the that table.?
What can I do now, can you please explain me about this point.
Waiting for your reply.
Thanks and Regards
Rajesh

About cluster table in sql server or SAP

Hello Gurus,
we have a cluster table "KONV" in our sql server 2008 , is that feature for cluster table native feature in sql server or in sap?
because some professonal said there is no concept for cluster table in sql server just like oracle database. so please help me for
clarification.
Many thanks,

I agree, this is ABAP Dictionary specific way of data encapulation, not the DB type dependant one. Basically it stores the data in RAW or LRAW format.
Also be aware that we distinguish b/w [data clusters|http://help.sap.com/saphelp_nw04/helpdata/en/fc/eb3bf8358411d1829f0000e829fbfe/frameset.htm] and [cluster tables|http://help.sap.com/saphelp_nw04/helpdata/en/cf/21f083446011d189700000e8322d00/content.htm].

Edit next extent size of the Cluster table

Hi Guys
I need to change the next extent size of the a table.
I ran se14 but i am not able to get into edit mode, because there is no button for edit mode.
Reason: Cluster table
Two questions:
1. Why there is no Edit button? Is it because this table doesnot exixt at DB level.
2. How can i change the next extent size for a Cluster table from sql prompt or from brtools if possible.
Information:
I am facing this issue only in DEV, QAS boxes, where as in Production its fine.
Regards
Ricky
Edited by: Ricky kayshap on Dec 9, 2008 3:52 PM

Hi,
Cluster Tables doesn't exist in DB, Because of that you can't make changes to extents at DB level.
if you experiencing some space issue. I woud suggest to check the underline Transparent tables and make changes to those.
hope this helps.

How can I get data in flat file from Pool table and cluster table ?

Hi,
I am working in one Achiving project. My requirement is to get data into flat file from Cluster table and pool table.
Is there any tool avilable to download data into flat file from pool table and cluster table ?
if table name given in the selection screen then data will be downloaded into flat file.
waiting for quick response.
Best Regards,
Bansidhar

Data cannot be retrived directly form the cluster table
as the Cluster results are stored in Cluster Key say for example PCLkey
and form that Key we need to fetch the data
these clustes are not the part of PNP or PNPCE tables

View on cluster table

hi all,
I am trying to create a view for the tables bkpg and bseg.but am unable to as the error is "bseg is cluster table".
can't we create view for cluster table. if can, how

You cannot create a view because BSEG is in a cluster table
For this reason SAP has provided some "secondary index" tables, look for :
     BSAD     Accounting: Secondary Index for Customers (Cleared Items)
     BSAK     Accounting: Secondary Index for Vendors (Cleared Items)
     BSAS     Accounting: Secondary Index for G/L Accounts (Cleared Items)
     BSID     Accounting: Secondary Index for Customers
     BSIK     Accounting: Secondary Index for Vendors
     BSIM     Secondary Index, Documents for Material
     BSIS     Accounting: Secondary Index for G/L Accounts

I am new to BW and SDN.
I have to see data in a cluster table.
I went to SE11, selected data type as KOMV, it displayed table, but data content button is greyed out.
Can someone please tell me how to view the data?
Thanks
Priya

Hi,
Thanks, I can see the data now.I am expecting that data should display in the 2LIS_VDKON extractor.There are two records for particular condition type.Item 10 and Item 20, but in RSA3, it is showing only one record for Item 20 and not showing for Item 10.
I have cleaned and filled the setup tables, but still no luck.
Can you please guide me, where else to look?

How to fetch data for a struture from a cluster table

How can I fetch data for a struture, from a cluster table, based on the name of the structure?

Hi,
In order to read from Cluster DB Table use the following statement:
Syntax
IMPORT <f1> [ TO < g1 > ] <f2> [TO < g2 >] ...
FROM DATABASE <dbtab>(<ar>)
[CLIENT <cli>] ID <key>|MAJOR-ID <maid> [MINOR-ID <miid>].
This statement reads the data objects specified in the list from a cluster in the database <dbtab>.
You must declare <dbtab> using a TABLES statement. If you do not use the TO <gi> option, the
data object <fi> in the database is assigned to the data object in the program with the same
name. If you do use the option, the data object <fi> is read from the database into the field <gi>.
For <ar>, enter the two-character area ID for the cluster in the database. The name <key>
identifies the data in the database. Its maximum length depends on the length of the name field
in <dbtab>.
The CLIENT <cli> option allows you to disable the automatic client handling of a client-specific cluster database, and specify the client yourself. The addition must always come directly after the name of the database.
For Eg:
PROGRAM SAPMZTS3.
TABLES INDX.
DATA: BEGIN OF JTAB OCCURS 100,
COL1 TYPE I,
COL2 TYPE I,
END OF JTAB.
IMPORT ITAB TO JTAB FROM DATABASE INDX(HK) ID 'Table'.
WRITE: / 'AEDAT:', INDX-AEDAT,
/ 'USERA:', INDX-USERA,
/ 'PGMID:', INDX-PGMID.
SKIP.
WRITE 'JTAB:'.
LOOP AT JTAB FROM 1 TO 5.
WRITE: / JTAB-COL1, JTAB-COL2.
ENDLOOP.

Neha
