HOW TO ADD DETAILS TO MULTIPLE TABLE(its urgent)

Hi All,
I have created one table called employee_master which records all the details of employee.
The problem which i am facing is if the employee wants to update the details then it is over writing the original record in the master table.
what i want to do is if the employee is updating a record then it should be updated and stored in the different table and should not over write the original record of employee master table. and in future the modified data should be available to the employee.
to do this what i need to do. whether i need to create one more table or it can be done in employee master only. I am new to this application so don't know how to do it.
need help urgently.

Hi,
This is your third message on the exact same question. Why don't you stick to one thread instead of duplicating the same question over and over.
its urgentPeople on here are volunteers and will help you when they get a chance. So that comment is unnecessary.
I believe your second thread, the responses presented gave the options to you. Anyway, the correct technique instead of creating a new thread when you have a reply, is to reply in the actual thread you created. Incase you can't find it, here is the URL: can we keep the original record as it is and create a version for it

Disable Statistics for specific Tables

Is it possible to disable statistics for specific tables???

If you want to stop gathering statistics for certain tables, you would simply not call DBMS_STATS.GATHER_TABLE_STATS on those particular tables (I'm assuming that is how you are gathering statistics at the moment). The old statistics will remain around for the CBO, but they won't be updated. Is that really what you want?
If you are currently using GATHER_SCHEMA_STATS to gather statistics, you would have to convert to calling GATHER_TABLE_STATS on each table. You'll probably want to have a table set up that lists what tables to exclude and use that in the procedure that calls GATHER_TABLE_STATS.

What is authorization object and how to create it for a table

Hi All,
What is authorization object and how to create it for a table?
Thanks

Hi
Authorization
For authorization checks, there are many ways of linking authorization objects with user actions in an SAP system. The following discusses three possibilities in the context of ABAP programming.
Authorization Check for Transactions
You can directly link authorization objects with transaction codes. You can enter values for the fields of an authorization object in the transaction maintenance. Before the transaction is executed, the system compares these values with the values in the user master record and only starts the transaction if the appropriate authorization exists.
Authorization Check for ABAP Programs
For ABAP programs, the two objects S_DEVELOP (program development and program execution) and S_PROGRAM (program maintenance) exist. They contains a field P_GROUP that is connected with the program attribute authorization group. Thus, you can assign users program-specific authorizations for individual ABAP programs.
Authorization Check in ABAP Programs
A more sophisticated, user-programmed authorization check is possible using the Authority-Check statement. It allows you to check the entries in the user master record for specific authorization objects against any other values. Therefore, if a transaction or program is not sufficiently protected or not every user that is authorized to use the program can also execute all the actions, this statement must be used.
AUTHORITY-CHECK OBJECT object
                        ID name1 FIELD f1
                        ID name2 FIELD f2
                        ID namen FIELD fn.
object is the name of an authorization object. With name1, name2 ... , and so on, you must list all fields of the authorization object object. With f1, f2 ... , and so on, you must specify the values that the system is to check against the entries in the relevant authorization of the user master record. The AUTHORITY-CHECK statement searches for the specified object in the user profile and checks the useru2019s authorizations for all values of f1, f2 ... . You can avoid checking a field name1, name2 ... by replacing FIELD f1 FIELD f2 with DUMMY.
After the FIELD addition, you can only specify an elementary field, not a selection table. However, there are function modules available that execute the AUTHORITY-CHECK statement for all values of selection tables. The AUTHORITY-CHECK statement is supported by a statement pattern.
Only if the user has all authorizations, is the return value sy-subrc of the AUTHORITY-CHECK statement set to 0. The most important return values are:
·        0: The user has an authorization for all specified values.
·        4: The user does not have the authorization.
·        8: The number of specified fields is incorrect.
·        12: The specified authorization object does not exist.
A list of all possible return values is available in the ABAP keyword documentation. The content of sy-subrc has to be closely examined to ascertain the result of the authorization check and react accordingly.

How to change tablespace for a table in 10g?

Does anyone know how to change tablespace for a table (like changing tablespace for an index [alter index ... rebuild tablespace ... ])? Many thanks in advance.

You need to rebuild the indexes after the move.

Unable to generate statistics for the table

I have got a staging table of more than 600 columns which has got range portioning. Size of the table is 4GB. The average size of the row is around 3 MB. I have created a Functional index on one of the column ABC VARCHAR2(50) and it has only number values. Now when I try generating statistics for this table through ANALYZE or DBMS_STAT, it gives Invalid Number error but when I drop this index and try analyzing, it works.
Executed TO_NUMBER(ABC) query on the table and it works fine.
I have got Functional Indexes on other tables also but I don't get such problem with those tables. I tried dropping the index and re-creating it but it didn't work out.
I was suspecting DATA BLOCK CORRUPTION so checked ALERT LOG and TRACE FILES but found nothing.
So what is this magic called?

I am using TO_NUMBER on the column.
I have checked the MetaLink for the same problem but could not find anything on that. I still suspect datafile error which I am unable to get in ALERT LOG or TRACE FILES. So I am going to try it this way:
1) Create new Tablespace with New Datafile
2) Transfer the table from existing Tablespace to new Tablespace
3) Create the functional index in the same new Tablespace
4) Try generating the statistics.
5) If it works then create seprate Tablespace for data and Index.
Hope it works !!
Thanks for the reply guys.

How to reduce time for gather statistics for a table.

I have a table size 520 gb
Its one of the partition size is 38 gb
and total indexes of related table is 412 gb.
Server/instance details.
==========
56 cpu -> Hyper threading enable
280 gb ram
35 gb sga
27 gb buffer cache
4.5 gb shared pool size
25 gb pga
undo size 90gb
temp size 150 gb
Details :
exec dbms_stats.gather_table_stats('OWNER','TAB_NAME',PARTNAME=>'PART_NAME',CASCADE=>FALSE,ESTIMATE_PERCENT=>10,DEGREE=>30,NO_INVALIDATE=>TRUE);
when i am firing this in an ideal time when there is no load that time also is is taking 28 mins to complete.
Can anybody please reply me how can we reduce the stats gather time.
Thanks in advance,
Tapas Karmakar
Oracle DBA.

Enable tracing to see where the time is going.
parallel 30 seems optimistic - unless you have a large number of discs to support the I/O ?
you haven't limited histogram collection, and most of the time spent of histograms may be wasted time - what histograms do you really need, and how many does Oracle analyse for and then discard ?
Using a block sample may help slightly
You haven't limited the granularity of the stats collection to the partition - the default is partition plus table, so I think you're also doing a massive sample on the table after completing the partition. Is this what you want to do, or do you have an alternative strategy for generating table-level stats.

How to maintain default values for custom table fields -- Urgent

Hi all,
I've a requirement wherein i need to create a Z table (with maintainence view) in which i'll have date and time as two of its field which should have current date and current time as default value. Can somebody suggest as how am i to maintain the date and time fields defaulting to current date and current time.
Incase if someone is unable to intrepret what i'm trying to say, please query me, i'll elaborate it further.
Please give in your quick inputs which is highly valuable to me and also will be highly appreciated.
Thanks in advance,
Vaishnavi Varadarajan

We have a following custom table which contains the fields Date on which record was created and Name of the person who created the object. We would like to have these to be filled up with SY-DATUM and SY-UNAME respectively.
Using the events, we can achieve this.
Please refer the following link:
http://abapliveinfo.blogspot.com/2007/12/events-in-table-maintenance-in-sap.html
Also,
Write a form routine in table maintanance generator.
1. SE11 > utilities > table maintenance generator
2. environment > modification > event
define the event and form routine to make use of the tigger. in the form routine define an object for the class and call the relevant method.
Or u can do it as:
Table maintenance generator is basically used to do table operations like (insert, delete, modify...).
if you create table maintenance for your table it will build a module pool program, by using you do the above operations.
below is the procedure to create table maintenance generator.
1) Create one function group.
2) after activating your Ztable, choose 'Utilities'----> 'Table maintenance genrator'.
3) then give the authorization group and function group created abobe in the next screen.
4) Then choose the "create" button in your application tool bar, which will creates the module pool program.
5) then create one Tcode by chosing "Transaction with parameters( parameter transaction)".
6) in transaction field give "SM30", select the check box "Skip initial screen".
7) in the below of that screen you can find the "Default values" frame.
8) there under the "name of screen field" select the "View name' and 'update".
9) in value column against to "view name" give you table name, and against to "Update" put 'X' in capital letters.
save it then you can straight away use this newly created Tcode to maintain your table.
Note:- 1) make the modification while saving the data into your table using this newly generated program to carry out your validation (even though it looks like standard program; no need to enter the access key).
2) if you do any changes to your table and press the activate button automatically the table maintenace generator will be goes off, you need to create this again.

How to create statistics for INDEX thru GUI

In DB13 i see messages MISSING_STATISTICS for some indexes.
I manage for tables thru DB20. How can i create statistsics for INDEX.
Rgds
PR

Hello PR,
at first let's say you should use the BRTools to create statistics for the indexes, because of the sample method (estimate, compute) - SAP has an algorithm to choose the right sample size.
Have a look at here:
http://help.sap.com/saphelp_nw70/helpdata/en/f4/81e93a637bfd70e10000000a11402f/content.htm
If you want to create statistics manually out of the R/3 ... you can use the report "RSANAORA"
Transaction SE38 -> Report RSANAORA -> Choose your index and sample method... and go on.

IP: How to build a single planning table

Hi,
Could somebody tell me how could I build a single planning table (without fact column) for BEx Analyzer? If I put only the plan column into the input ready query, than the Analyzer not displaying any data ("there aren't data to display"). Recently we define a hidden fact column next to plan data, but I think there are better way to solve this problem...
Regards,
Adam

Hi.
As I can understand, you want to show blank cells fof entering a planning data ?
Just set to "mater data" access for the characteristic in BEX.
This way all master data values of the characteristic will appear with blank key figures.
