How to find the deletions in an ODS

Hi experts,
We have some records missing in a ods. Unable to find how those records are missing.
Is there any solution to check if any deletions ( selective deletion or request wise deletions ) are made on an ods.
Regards,
Bhadri M.

Hi Bhadri,
Apart from what others have suggested ...........
Go to the Process Monitor/manage Screen of the DSO ..u can find a Deletion falg/mark on the request for which the data
has been deleted....observe it carefully ...

How to find the deleted data in tables

guys,
how to find the deleted data in tables example: i want to see whether anyone deleted data in MB5B report tables like mbew, etc.,
regards,

Hi,
MBEWH is actually the history table of MBEW. It will record all the changes. As I have told you earlier if you have deleted the record dirctly from the table then it will not come even in the table MBEWH
That means no changes have been made.

How to find the deleted transport req logs.

Hello gurus,
in my DEV box some body was deleted the transport request.
i need to know that by whom that request was deleted. the thing is that request was not released and not imported into any system. that request was deleted after the creation.
but now i am confused how to check the logs. i have searched the log file in trans directory and also SLOG,ALOG.
i guess there is no use of import history in STMS because that request not existed in the system?
then how can i find the deleted person. and time.
Could you please do let me know.
help would be heighly appreciated.
Regards,
srini.

hi!
Are you sure that the transport request was deleted?
Perhaps Transport request is a local transport and when you release the transport it will not create the export files.

How to find the datasource of an ODS which is not activated yet in Metadata

Through SAP Help, we find a useful ODS that we want to use to build up queries, but it's not easy to locate the Infosource and Datasource of it through the SAP Help. I remember there is a functionality in the Metadata Repository that the data flow of an InfoCube or ODS can be shown there. I get to the Metadata Repository and locate the ODS already, but can't find the functionality any more that can show the data flow of the ODS. If I can see the data flow, then I think I can find the corresponding infosource and datasource of it. Anyone's input is greatly appreciated!

hello Bhanu,
From SAP Help, find the known Infosource help document, I copy part of the documentation below (see in between two dashed lines):
Document History (Item Level)
Technical name: 0BBP_DOC_ITM_1
Based on DataSource: Customer-specific name space, for example ZBBP_TD_DOC_I
The help uses the datasource name starting with Z, does it mean there is no datasource on R3 side that we need to manually create it?
Thanks

How to find the number of records in ods?

how to find the number of records in ods?
Pls suggest the solution apart going to the table of ods and seeing the number of records.
Is there any program or function module to see the number of records in ods?
For eg: SAP_INFOCUBE_DESIGNS is a program which gives the detail (number of records) of infocube.

Hi,
I was looking at this and found the following tables that may be of help.
One of these tables will include a summary of the record count of all the tables in your system based on the last time each table had it's database statistics calculated:
DBSTATTADA
DBSTATTDB2
DBSTATTDB4
DBSTATTDB6
DBSTATTINF
DBSTATTMSS
DBSTATTORA
We run on an Oracle database so the table record counts can be taken from DBSTATTORA. Type in AZ in table selection field in SE16 to restrict the output to ODS (or DSO) tables only.
The record count is at the time indicated in the timestamp field. Obviously this is not real time but should not be too out of date - if it is you may be having performance issues and should get your DBA / Basis to run a full refresh of DB stats.
Hope this helps, alhtough not real time the table should give you a decent indication of the size of all your ODS objects (or any other table for that matter!)

How to find the user who deleted the contents of DSO.

Dear friends,
Can u please tell me ,how to find the user who deleted the contents of the DSO.
The user has deleted the complete contents of the DSO. We need to find the user ,date and time.
regards,
Vijai

Hi,
If the user has used the manage option to delete the contents of the DSO then the changed by field will be updated by the users name. In case a program is used for the deletion then it wont be the case.

How to find the file that delete from time capsule?

How to find the file that delete from time capsule?

I mean I saved JPEG file in Time capsule and unfortunately delete the file. Can I get it back
IF.... .no other backups have occured since you deleted the file, you might be able to retrieve it using an application like Disk Warrior. It's about $100 as I recall, and there are no guarantees that it will work.
DiskWarrior 4 - The Disk Utility for Mac Disk Repair, Mac Directory ...
Any of the free or low priced utilities that you might see or try will not be able to retrieve a deleted file from a Time Capsule.
If any backups have occured since you deleted the file, the deleted file has almost certainly been overwritten. No way to retrieve it in that case.

How to find the number of records per months in cube

Hi,
how to find the number of records per months for my all cubes?
Can i use the ListCube transaction to find totl number f records per cube monthwise ?
Jimmy

Hi,
Here is a program to generate no of records and list of ODS and Cubes in Active version.Schedule this program in background and create a cube to load this information and schedule to the data from the file generated by the program. Schedule this all per you requirement.
1.Copy the code into your Z<programname> from Se38.
2.change the FILENAME in CALL FUNCTION 'GUI_DOWNLOAD' in the program to the location from where you can pick the information to load data to cube(eg Application server).
3.Save program.
4.Schedule the program in background as required
5.Create cube with infoobjects to hold no of records and Infoprovider name
6.Load this cube based on event after the program job is done.
Hence you can report on this cube to see no of records in CUBE or ODS in your box.
Please find the code below.

How to find the number of references created for a given object ??

How to find the number of references created for a given object in a big application environment.
That means, if i give any object name (of my application) as input, then how can i find the[b] number of references created for that particular object ??

Please do not post the same question multiple times.
As for your original question, there is no direct way to do it.
Especially not the way you phrased it,
since objects don't have "names".
Applications also don't have "names".
They have classes and instances.
Also, there are 2 related issues, and I'm not sure which one is the one you asked.
#1. Finding the number of references to the same object.
Eg.
Map<String,String> a = new HashMap<String,String>();
Map<String,String> b = new HashMap<String,String>();
Map<String,String> c = a;In this case, there are only 2 objects.
The first object has (at least) 2 references pointing to it.
The second object has (at least) 1 reference pointing to it.
(There may be more, if the HashMap library keeps
references to these things, or if the HashMap object has
some internal cyclic references...)
If you're asking this, then it can't be done.
It's an active research topic in universities
and software research labs, called "alias analysis".
Type it in google, and you'll see people are working hard
and having little success so far.
#2. Finding the number of instances created from a class.
In this case, what you have to do is to add a counter to
the constructor of the class. Every time an object is constructed,
you increment the counter. Like this:
   class MyClass
       public static int counter = 0;
       public MyClass( ) { counter++; }
    // Then later in your program, you can do this:
    MyClass a = new MyClass();
    MyClass b = new MyClass();
    System.out.println(MyClass.counter); // It should show 2Note: you won't be able to do this to every class in the system.
For every class you care about, you have to modify its constructor.
Also: when an object is deleted, you won't always know it
(and thus you won't always be able to decrement the counter).
Finalizers cannot always work (read Joshua Bloch's
"Effective Java" book if you don't believe me), but basically
(1) finalizers will not always be called, and
(2) finalizers can sometimes cause objects to not be deleted,
and thus the JVM will run out of memory and crash

How to find the level of each child table in a relational model?

Earthlings,
I need your help and I know that, 'yes, we can change'. Change this thread to a answered question.
So: How to find the level of each child table in a relational model?
I have a relacional database (9.2), all right?!
     O /* This is a child who makes N references to each of the follow N parent tables (here: three), and so on. */
    /↑\ Fks
   O"O O" <-- level 2 for first table (circle)
/↑\ Fks
"o"o"o" <-- level 1 for middle table (circle)
   ↑ Fk
"º"Tips:
- each circle represents a table;
- red tables no have foreign key
- the table in first line of tree, for example, has level 3, but when 3 becomes N? How much is N? This's the question.
I started thinking about the following:
First I have to know how to take the children:
select distinct child.table_name child
from all_cons_columns father
join all_cons_columns child
using (owner, position)
join (select child.owner,
               child.constraint_name fk,
               child.table_name child,
               child.r_constraint_name pk,
               father.table_name father
          from all_constraints father, all_constraints child
         where child.r_owner = father.owner
           and child.r_constraint_name = father.constraint_name
           and father.constraint_type in ('P', 'U')
           and child.constraint_type = 'R'
           and child.owner = 'OWNER') aux
using (owner)
where child.constraint_name = aux.fk
   and child.table_name = aux.child
   and father.constraint_name = aux.pk
   and father.table_name = aux.father;Thinking...

My thanks in advance,

Justin,
Understood.
Nocycle not work in 9.2 and, even that would work, would not be appropriate.
With your help, I decided a much simpler way (but there is still a small problem, <font color=red>IN RED</font>):

How to find the most matched values in the set of map?

Hi friends!
I have two vectors
vector<int> V1; vector<int> V2;
and a map<int, set<int>> M1;
I want to select common values from both V1 and V2 and check those values with the set in the map M1.
For example:
V1 contains;
2 4 6 8 9
V2 contains;
4 5 6 9 10
M1 contains;
1=>1 2 5 9
2=>4
3=>5 10
4=>2 4 8
5=>4 9
6=>4 6
7=>9 12
When we select the common values of V1 and V2 it is 4, 6, 9.
And we search for all 4, 6, 9 from the values of M1 which give more appropriate.
But, no all values in the set of map.
Then, we delete any value from 4, 6, 9, then remaining values would match any values from the map.
From the example, if we delete 6, then remaining 4, 9 will match with 5=>4 9, or if we delete 9, then 6=>4 6. Any one of the keys can be selected.
I know how to select the common values from V1 and V2, but I do not know how to match with the values and select the appropriate key from M1.
Could anyone help me to solve this?

This is not the question you asked, except perhaps in the subject. The subject is not the right place to put key features of the question. It is also important to use the body to ask just the question you want
answered. For example your real question has nothing to do with V1 and V2, just the common vector V (e.g. 4 6 9).
One way to solve your problem would be to create a new map
map<int, set<int>> M2;
with the same keys as M1. Each set of M2 should contain the elements of V that are
not in the corresponding set of M1.
Then pick the key of M2 that has the smallest set. If that set is empty, then the whole of V can be used. Otherwise the smallest set tells which elements of V have to be removed, and which is the desired key of M1.
In your example, key 5 of M2 will contain just 6, so you should remove 6 from V and select key 5.
Yes fine. I tried the following code and it creates the map M2 (NewMyMap in my code). But how to find the smallest set starting from size 1?
