More indexes in SAP tables

Hi,
It might be interesting for you and us to enhance the indexes on SAP tables, in order to speed up the searches or queries with criteria...
For example, it's primary to have an index based on the ItemCode for the OWOR tableu2026 because we will often search for Production orders of a specific itemu2026
Actually, we have only those indexes :
- OWOR_NUM: DocNum, PIndicator
- OWOR_PRIMARY: DocEntry
Also, for activities, it could be very helpful to have an index to know which activities have a reminderu2026
Actually we have only those ones :
- OCLG_CRD_CODE nonclustered located on PRIMARY CardCode
- OCLG_OPPORT nonclustered located on PRIMARY OprId, OprLine
- OCLG_PRIMARY clustered, unique, primary key located on PRIMARY ClgCode
And when we want to do that kind of query, it can be so long without any index !!
SELECT T0.[ClgCode], T0.[Action], T0.[Details], T1.[Name], T0.[Recontact], T0.[BeginTime],
T0.[AttendUser]
FROM [dbo].[OCLG] T0
LEFT OUTER JOIN [dbo].[OCLO] T1 ON T1.[Code] = T0.[Location]
WHERE T0.[Reminder] = ('Y') AND T0.[RemSented] = ('N') AND (T0.[RemDate] < ('2008-12-29 00:00:00:000') OR (T0.[RemDate] = ('2008-12-29 00:00:00:000')
AND T0.[RemTime] <= (1632) ))
Is it planned to be enhanced in future releases ?
thanks,

Hi
We would like to see the following batch detail database fields indexed:
IBT1.BaseType
IBT1.BaseEntry
IBT1.BaseLinNum
We already have over 75,000 batch detail records and we would like to quickly report on batches. Once the fields have been indexed, we will be able to create a fast join to the OINM table where the fields:
OINM.TransType
OINM.CreatedBy
OINM.DocLineNum
are already indexed. This will allow us to produce rapid reports and analysis, e.g. for our own FIFO stock calculations. Anyone else find stock reports slow ?

Creating index for standard SAP tables

Hi!
What are the advantages and disadvantages of creating addtional indexes for tables with massive amount of data (BSEG, BKPF, COEP, etc...).
If I create a new index it supposed to make the table access faster, for the cost of hard disk space.
Am I right?
Thank you

Hi,
Primary and secondary indexes
Index: Technical key of a database table.
Primary index: The primary index contains the key fields of the table and a pointer to the non-key fields of the table. The primary index is created automatically when the table is created in the database.
Secondary index: Additional indexes could be created considering the most frequently accessed dimensions of the table.
Structure of an Index
An index can be used to speed up the selection of data records from a table.
An index can be considered to be a copy of a database table reduced to certain fields. The data is stored in sorted form in this copy. This sorting permits fast access to the records of the table (for example using a binary search). Not all of the fields of the table are contained in the index. The index also contains a pointer from the index entry to the corresponding table entry to permit all the field contents to be read.
When creating indexes, please note that:
An index can only be used up to the last specified field in the selection! The fields which are specified in the WHERE clause for a large number of selections should be in the first position.
Only those fields whose values significantly restrict the amount of data are meaningful in an index.
When you change a data record of a table, you must adjust the index sorting. Tables whose contents are frequently changed therefore should not have too many indexes.
Make sure that the indexes on a table are as disjunctive as possible.
(That is they should contain as few fields in common as possible. If two indexes on a table have a large number of common fields, this could make it more difficult for the optimizer to choose the most selective index.)
Accessing tables using Indexes
The database optimizer decides which index on the table should be used by the database to access data records.
You must distinguish between the primary index and secondary indexes of a table. The primary index contains the key fields of the table. The primary index is automatically created in the database when the table is activated. If a large table is frequently accessed such that it is not possible to apply primary index sorting, you should create secondary indexes for the table.
The indexes on a table have a three-character index ID. '0' is reserved for the primary index. Customers can create their own indexes on SAP tables; their IDs must begin with Y or Z.
If the index fields have key function, i.e. they already uniquely identify each record of the table, an index can be called a unique index. This ensures that there are no duplicate index fields in the database.
When you define a secondary index in the ABAP Dictionary, you can specify whether it should be created on the database when it is activated. Some indexes only result in a gain in performance for certain database systems. You can therefore specify a list of database systems when you define an index. The index is then only created on the specified database systems when activated

Problem while creating index for temporary table...

Hi,
i have created index for a temporary table and this script should used by multiusers.So when second user connecting to it is giving index i mean object already exists.
So what i need is when the second user connected the script should create one more index on temporary table.Will sql server provide any random way of creating indexes if the index exists already with that name??
Thank You,

Nope..
SQL Server is cleaver enough to handel this situation.
When you create a index or constraint on the Temp Table, eventhough the index name is duplicate it will allow.
But it only possible on temp tables (prefixed with single #).
To Test this,
Open Two window,
Execute the below window on the opened 2 window..
create table #test
id int
Insert Into #test values(1);
Insert Into #test values(2);
Create clustered index testindex on #test(id)
Now you wont get any error on any of the window. Rite?
To fetch the created index details, execute the below code on any one of the window..
select * from sysindexes where name like '%test%'
Now you can see the 2 rows with same indexname but refereing with different table. Yes. all the temp tables (#) will be suffixed with unique number to avoid the object already found error while multiple users connects.

SAP Table index size is greater than the size of the actual table

Hello Experts,
We are resolving an issue related to database performance. The present database size is 9 Terabytes. The analysis of response times through ST03N shows that the db time is 50% of the total response time. We are planning to reorganize the most updated tables (found from DB02old tx).
Here we see that the size of the index for a table is greater than the actual size of the table. Is this possible, if yes then how can we reorganize the index as it does not allow us to reorganize the index using brspace command.
Hope to hear from you soon, and if any additional activities you can suggest to improve the performance of the database will be appreciated.
Thank you

Hi Zaheer,
online redef may help you (for a little while) , but also check WHY the index became fragmented.
Improper settings can bring the index fragmented again and you have reoccuring reorg needs.
i.e.
check if PCT_INCREASE >0 if you are using Dictionary Managed Tablespaces or locally managed tablespaces that uses a "User" allocation policy. Set it to 0 to generate uniform next extents in the online reorg.
select
            SEGMENT_NAME,
            SEGMENT_TYPE,
            round((NEXT_EXTENT*BLOCKS)/(EXTENTS*BYTES))*(BYTES/BLOCKS),
            PCT_INCREASE
        from
            DBA_SEGMENTS
        where
            OWNER='SAPR3'
        and
            SEGMENT_TYPE in ('INDEX',
                            'TABLE')
        and
            PCT_INCREASE > 0
        and segment_name in ('Yourtable','Yourindex')
In the following cases, it may be worthwhile to rebuild the index:
     --> the percentage of the space used is bad - lower than 66%: PCT_USED
     --> deleted leaf blocks represent more than 20% of total leaf blocks: DEL_LF_ROWS
     --> the height of the tree is bigger than 3: HEIGHT or BLEVEL

Creation of secondary index on RSPCPROCESSLOG table

Hello guys,
We have detected severe performance issues while executing the transaction ST03n in our BW 3.5 System.
Looking in the OSS notes we found the note "SAP Note 841324 - ST03N: poor performance for process chain profile" where it recommends the creation of a secondary index in the table RSPCPROCESSLOG with the following features:
Create another secondary index on the RSPCPROCESSLOG table with the
following fields:
- INSTANCE
- TYPE
Can you please let us know what is the step by step to proceed with the creation of this secondary index?
Thanks for your help.

View with SAP tables fails with "No Owner" error

Dear experts,
We have created a view (VIEW_MARA_MAKT) on Information Steward (4.2 SP1) using SAP tables MARA and MAKT. This view is working perfectly. Next we create another view to join with our previous view (VIEW_MARA_MAKT) to table MARC. The view validates correctly, but when trying to view the data we get the following error:

It appears that DS is not satisfied that there is no owner name sent from IS, but for SAP connections it is not possible to specify owner names when adding the tables to IS.
Please can you give some recommendations to resolve this error.

What you can do is to use a table of record.
And create a block based on stored procedure.
Below is a table of record and procedure for querying from multi-tables.
If you want to update, insert, delete rows, you need to create 3 more procedures on the package. One for updating, another for inserting, and so on.
I never done updaing part before. So I need to spend time for coding.
If you want, I can post later as soon as I got it.
CREATE OR REPLACE PACKAGE TEST5 AS

SECOND TEST1.SECOND%TYPE,

Local index vs global index in partitioned tables

Hi,
I want to know the differences between a global and a local index.
I'm working with partitioned tables about 10 millons rows and 40 partitions.
I know that when your table is partitioned and your index non-partitioned is possible that
some database operations make your index unusable and you have tu rebuid it, for example
when yo truncate a partition your global index results unusable, is there any other operation
that make the global index unusable??
I think that the advantage of a global index is that takes less space than a local and is easier to rebuild,
and the advantage of a local index is that is more effective resolving a query isn't it???
Any advice and help about local vs global index in partitioned tables will be greatly apreciatted.
Thanks in advance

here is the documentation -> http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14220/partconc.htm#sthref2570
In general, you should use global indexes for OLTP applications and local indexes for data warehousing or DSS applications. Also, whenever possible, you should try to use local indexes because they are easier to manage. When deciding what kind of partitioned index to use, you should consider the following guidelines in order:
1. If the table partitioning column is a subset of the index keys, use a local index. If this is the case, you are finished. If this is not the case, continue to guideline 2.
2. If the index is unique, use a global index. If this is the case, you are finished. If this is not the case, continue to guideline 3.
3. If your priority is manageability, use a local index. If this is the case, you are finished. If this is not the case, continue to guideline 4.
4. If the application is an OLTP one and users need quick response times, use a global index. If the application is a DSS one and users are more interested in throughput, use a local index.
Kind regards,

How to select LAST line from a SAP table?

Hi developers,
I need to select the last line from a SAP table, NOT from an internal table.
Something like
SELECT SINGLE LAST FROM pa00169..
any help is more than welcome.

Javier,
Based on this statement from you:
"i created a Z table, its a config table that stores some bussines rules, and an id counter, so in order to update that counter i need the last line of the ztable."
I have one additional solution which is the "text box" approach IF the 'id counter' mentioned above is a numeric data type.
If so, use an SQL function to get the highest value of ID_COUNTER.
Then simply add one to it to produce a new, unique, higher-order primary key.
See below:
data: l_id_counter like ztable-id_counter.
data: new_id_counter like ztable-id_counter.
select max( ID_COUNTER ) from ztable into l_id_counter.
new_id_counter = l_i_counter + 1.
Now new_id_counter will be the unique, primary key IF this is the only field in ZTABLE's primary key.
This will also GUARANTEE that your new record is built correctly.

Best way of Using Index on a Table.

I am trying to understand the phenomena of using INDEX on a Table
need some guidance!!!
Let us take this scenario
I have a table "MYRECORD" which has 4 attributes(or coulombs)
1. "STATE" (varchar) // this can have 49 different values like newyork, dehli etc
2. "YEAR" //a year like 2007
3. "MONTH" //a month like JAN,FEB etc
4. "CAT" (int) // type(category) of data represented by values 0 to 40
with a PRIMARY KEY(STATE,YEAR,MONTH,CAT)
now i will create index
1. INX_myrecord (STATE,YEAR,MONTH) on table MYRECORD
so now my question is
1. what is the effect on performance of DB it makes?
2. when I use a query
SELECT * FROM MYRECORD WHERE STATE="dehli" AND YEAR=2007 AND MONTH="JAN";
how will it get processed if index is created and not created.
3. how can I refer a index by name in a query if so possible?
Cheers,
UD

You have edited your post. Now you have a primary key consisting of state, year, month and cat which makes an index on state, year and month useless as the already existing primary key can provide for retrieval of rows by index. If you don't have other columns - or just few other not being large varchar2 columns - you should have created the table as an IOT (Index Organized Table - avoiding to have separate table and index containing - nearly - the same data) in the first place.
As a primary key by definition can contain only unique non null values, a query like SELECT * FROM MYRECORD WHERE STATE='dehli' AND YEAR=2007 AND MONTH='JAN' cannot give you more than the number of distinct cat values (0 .. 40) + 1 (if cat can be null - presumed one/some of the corresponding state, year and month is not null)
The information processing depends principally of the query, the mere presence of an index does not make sure it will be used. If an index is used it means the index will be searched first then the table rows will be accessed by rowids contained in the index (usually a single row or a range of rows - a rather small number of them - is retrieved this way, your select for example). Submitting something like SELECT * FROM MYRECORD WHERE YEAR=2007 AND cat=33 would most likely produce a full table scan of myrecord table ignoring the primary key.

Reading TXT file to SAP table.

Hi everyone,
my task is to read data from chosen text file into table I created.
Text file look like this:
ID_ASK|DATA_OD|DATA_DO|
1234|20140517|20140824|
ID_MAG|ID_ASO|ID_KAT_ASO|SOURCE|NAME|
12|23|34|600156|TEST NAME1|
ID_MAG|ID_ASO|ID_KAT_ASO|SOURCE|NAME|
23|24|54|600156|TEST_NUMR2|
Header "ID_ASK|DATA_OD|DATA_DO|" occurs only once, while header "ID_MAG|ID_ASO|ID_KAT_ASO|SOURCE|NAME|" can occur many times.
I want to insert those values (except of headers, of course) into my SAP table:
Table Fields
Fields from file
ZIDASK
ID_ASK
ZIDMAG
ID_MAG
ZIDASO
ID_ASO
ZIDKAT
ID_KAT_ASO
ZZRCEL
SOURCE
ZDAOD
DATA_OD
ZDADO
DATA_DO
ZKATNAM
NAME
I want user to choose file from browser and I am using F4_FILENAME function.
1. To avoid reading header into table I think I'll use something like this (in loop, of course):
    IF (lv_linecounter MOD 2) = 1.
          CONTINUE.
    ELSE.
          SPLIT something AT '|' INTO those_fields.
2. What should be next function to call?
3. Is declaring separate types for those two headers a good idea?
TYPES: BEGIN OF ty_output_hdr,
   id_ask type zask-zidask,
   data_od TYPE zask-zdaod,
   data_do TYPE zask-zdado,
END OF ty_output_hdr.
TYPES: BEGIN OF ty_output_pos,
   id_mag TYPE zask-zidmag,
   id_aso TYPE zask-zidaso,
   id_kat_aso TYPE zask-zidkat,
   source TYPE zask-zzrcel,
   name TYPE zask-zkatnam,
END OF ty_output_pos.
With kind regards,
Bartlomiej

Hello Bartlomiej,
His logic for processing (item 1) is correct and you can do the processing in this way without any problems.
Regarding item 2, after the process of SPLIT, you can assign information to a structure and then insert the contents in the table individually.
SPLIT gs_line
    AT '|'
INTO gv_fieldA
      gv_fieldB
      gv_fieldC.
gs_data-fieldA = gv_fieldA.
gs_data-fieldB = gv_fieldB.
gs_data-FieldC = gv_fieldC.
INSERT FROM ZTABLE gs_data.
Regarding item 3, a separate statement, however it manages more lines, is the best method that can be applied, allowing a subsequent maintenance will not affect other component.
Regarding F4_FILENAME object, you can use it on AT SELECTION-SCREEN event of report:
AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_file.
CALL FUNCTION 'F4_FILENAME'
    EXPORTING
      program_name = syst-cprog
      dynpro_number = syst-dynnr
      field_name = '
    IMPORTING
      file_name = p_file.

How to copy the Data From Oracle Table To SAP Table

Hi Friends,
We need to copy the data from Oracle Database Table to SAP Table. The data should be updated simultaneously in both tables . Should I write a program that contains the native sql statement like EXEC SQL PERFORMING WRITE,....
I appreciate any suggestions regarding this.
Regards
CSM Reddy

Hi,
since you posted this question in the DB2 forum I assume that you are using a DB2 database for your SAP system.
To access a table from a legacy ORACLE database you may use the DBSL multiconnect feature. I.e. you open a secondary connecction in the SAP system to your ORALE database. You can then ready the data from the ORACLE database into an ABAP internal table and insert it afterwards into the DB2 table on the main connection.
Another way to access an ORACLE table from a DB2 database is to use the DB2 federated database feature. This requires a little bit more DB2 skill. With this feature you can make the ORACLE table visible within the DB2 database. To copy data you can then simply use a "INSERT ... SELECT" statement.
Regards
Frank
