Records with duplicate key in Infospoke

Hello
I have a question with regard to the output produced by a Delta Extraction Mode infospoke.
I have an Infospoke running across a single cube that pulls a number of characteristics and key figures from said cube. The infospoke uses delta extraction and is run as part of a process chain after the successful update of the said infocube.
The output file contains two records for each record that exists in the cube .....
The first record contains all the characteristics and the correct values for the key figures - this record corresponds with the associated record in the cube.
The second record contains all the characteristics as the previous record but, all the key figures contain '0' values.
The two records in the infospoke output file are always sequential. Every valid record (ie record I would expect to see) has a duplicate with '0' value key figures.
Has anyone experienced this? As the key figure values for the output always correspond when totalled I am not too concerned at this stage but just wondered if anyone has seen this before.
Thanks in advance for your help.
Sally

Hi Sally,
Info spoke first extract data from F fact table and then from E fact table. If you are extracting data into an table you can choose request id and package id as key on top of characteristics. But when you are extracting data into flat file you cant. so you will get multiple records.
Try to extract the data into a table and check the difference. If you have same characteristic combination records available in E & F fact table you will get 2 records in 2 different request nos(Check in the Open Hub Monitor).

The record has duplicate key values - "Include in Unique Index" checkbox missing

I have a Silverlight client app that I'm developing in Lightswitch in VS2013 Ultimate Update 1, and have run into a problem when adding records.
I am working against an external SQL Server 2008 database, and the table in question only has the primary key constraint, meaning that the ID field is an identity field, set as the primary key.
When I try and add records to the table from the app, I get an error "The Shiur record has duplicate key values." This seems to happen when I add a row that has the same Speaker as an existing one. If I add one with a new Speaker then
it inserts OK.
Whilst searching for information on this error, I saw many comments around about there being a problem in earlier releases with the "Include in Unique Index" not working properly. This looked like my problem, except for two points...
1) This table doesn't have anything in a unique index (as far as I know), as I never set it up to have any. You can see the details here...
This looks to me like there is only the one index, which is the primary key one.
2) The "Include in Unique Index" checkbox doesn't appear on my Properties panel at all. If I open the table in the designer, then click in the Speaker row, I don't see "Include in Unique Index" at all...
Actually, I don't see "Include in Unique Index" at all, irrespective of what I click. It's just not there.
So, I don't seem to have a unqiue constraint to violate, and VS doesn't show me the "Include in Unique Index" to allow me to check this, but I still get the error on insert. Anyone any ideas what's going on here?
Thanks

Hi Alan,
'Include in Unique Index' is for intrinsic database entity properties.
Ah, that explains why I can't see it then :)
Is LightSwitch or SQL throwing the error?
Ah, you're a genius! Well, not quite, but your question led me to the answer.
For some odd reason, the primary key fields on my tables seem to have lost their identity setting, so when it tried to insert a new record, the ID wasn't automatically increased, so was going in as zero. This worked fine for the first insert, as there wasn't
a record with zero ID, but failed for the second.
Changed the ID fields to be identity, and all works fine now :)
Thanks very much.

Error Record with Same Key

Can anyone help me out with a master data load failure.
My request goes off red and the message looks somehow like "Record filtered in advance as error records with the same key exist", "Filter out new records with same key". I have already checked the duplicate handle record setting in DTP. Still why am i getting this error.
Would appreciate if some one could suggest me in this.

Hello Shridevi M ,
When I execute my DTP, I get a master data load failure : "Record filtered in advance as error records with the same key exist" . It's the same as you get. Please tell me how did you solved this probelm?
Thanks in advance,

Optimal read write performance for data with duplicate keys

Hi,
I am constructing a database that will store data with duplicate keys.
For each key (a String) there will be multiple data objects, there is no upper limit to the number of data objects, but let's say there could be a million.
Data objects have a time-stamp (Long) field and a message (String) field.
At the moment I write these data objects into the database in chronological order, as i receive them, for any given key.
When I retrieve data for a key, and iterate across the duplicates for any given primary key using a cursor they are fetched in ascending chronological order.
What I would like to do is start fetching these records in reverse order, say just the last 10 records that were written to the database for a given key, and was wondering if anyone had some suggestions on the optimal way to do this.
I have considered writing data out in the order that i want to retrieve it, by supplying the database with a custom duplicate comparator. If I were to do this then the query above would return the latest data first, and I would be able to iterate over the most recent inserts quickly. but Is there a performance penalty paid on writing to the database if I do this?
I have also considered using the time-stamp field as the unique primary key for the primary database instead of the String, and creating a secondary database for the String, this would allow me to index into the data using a cursor join, but I'm not certain it would be any more performant, at least not on writing to the database, since it would result in a very flat b-tree.
Is there a fundamental choice that I will have to make between write versus read performance? Any suggestions on tackling this much appreciated.
Many Thanks,
Joel

Hi Joel,
Using a duplicate comparator will slow down Btree access (writes and reads) to
some degree because the comparator is called a lot during searching. But
whether this is a problem depends on whether your app is CPU bound and how much
CPU time your comparator uses. If you can avoid de-serializing the object in
the comparator, that will help. For example, if you keep the timestamp at the
beginning of the data and only read the one long timestamp field in your
comparator, that should be pretty fast.
Another approach is to store the negation of the timestamp so that records
are sorted naturally in reverse timestamp order.
Another approach is to read backwards using a cursor. This takes a couple
steps:
1) Find the last duplicate for the primary key you're interested in:
cursor.getSearchKey(keyOfInterest, ...)
status = cursor.getNextNoDup(...)
if (status == SUCCESS) {
      // Found the next primary key, now back up one record.
      status = cursor.getPrev(...)
} else {
      // This is the last primary key, find the last record.
      status = cursor.getLast(...)
}2) Scan backwards over the duplicates:
while (status == SUCCESS) {
      // Process one record
      // Move backwards
      status = cursor.getPrev(...)
}Finally another approach is to use a two-part primary key: {string,timestamp}.
Duplicates are not configured because every key is unique. I mention this
because using duplicates in JE has more overhead than using a unique primary
key. You can combine this with either of the above approaches -- using a
comparator, negating the timestamp, or scanning backwards.

There is already a record with duplicate customer/vendor reference number

Dear Expert,
Person "A" reject the Sale Order now Person "B" edit same SO and again send to "A",now second time "A" approval
"B" in aleart msg go to that approval,press "add" button got information (error)
"there is already a record with duplicate customer/vendor reference number"
what shud i do ?
and why in aleart message box two entry for same SO
1st is reject but show SO draft [approved]
2nd is approval ...
Thanks

hi,
U can change radio button option in per document tab of document settings for sales order,
Either change it to without warning / warning only When duplicated customer reference no. occurs.
Modify customer reference number by including dot at end.

Master data records with one key

Hello All,
I have scenario that I need to load the master data records with one key.
For ex--
Cluster            Dcode               version
5000                 DC1                  2008
5000                 DC1                  2008
5001                  DC1                  2009
Could you please let me know possible ways.
Thanks

In your case if Cluster is the key then the underlying attributes data will be overwritten when the same cluster key comes.
as per you example data finally it loads only two records in to the target, since first two records key is same.
Hope this helps.
Veerendra.

Package parametеr "overwrite records with match key" (BPC 10)

Hi all.
We load data from DSO in SAP BW to BPC. We use the /CPMB/LOAD_INFOPROVIDER process chain for that.
In the package we use the "overwrite records with match key" parameter for the "Handling of records in target" setting.
But if there's no data in the DSO, the package hangs in the "Running" status and won't finish loading.
If we start the package with the "append" parameter for the "Handling of records in target" setting, then package finishes with the warning status.
What could be the problem if use "overwrite records with match key" ?
Best regards,
Sergey

Hi,
As per the below note its known issue in SP08. In which version of BPC are you running now.

How to locate a record with multipute keys in dataprovider??

As above subject, I want to locate a record with multipute keys / searching criterias; my dataprovider is connected to a view of database table.

use:
findFirst(FieldKey[] fieldKeys, java.lang.Object[] values)
for example:
String[] keyf = {"FIELD1", "FIELD2"};
String[] keyval = { keyval1, keyval2};
RowKey rk = xxxDataProvider.findFirst(keyf, keyval);

Updating database table with DUPLICATE keys

i have an internal table having data as follows.
emp_id name date proj_id activity_id Hours Remarks

101 Pavan 09.10.2007 124 2 1.00 Documentation
102 Raj 09.10.2007 123 3 6.00 Testing
Now i need to update a Ztable with above mentioned data.
The structure of the Ztable is as follows.
Mandt emp_id name date proj_id activity_id Hours Remarks
NOte: i have ticked both check boxes for the field MANDT in table.
Rest didnt select the check boxes.
I believe now the field MANDT alone is a primary key for the z-table.
NOw i have tried with UPDATE/INSERT statments to update the database table.
But instead of inserting all the rows, the system is over writing on the same emp_id row.
Even tried with the statments like INSERT INTO <Ztable> values <Internal table> ACCEPTING DUPLICATE KEYS.
But its not getting inserted as a separate row in the table.
Requirement is to insert the multiple rows in the database table without any over writing activity.
Can anyone give me the code to do this?
Regards
Pavan

Hi Pavan,
 Please let me know what are the key fields in your Ztable. Try with below code it may help you. change the "Ztablename" as your database table name and I_INTERNAL TABLE as your internal table name. still you are facing the problem please let me know.
lock the custom table before updating the table.
CALL FUNCTION 'ENQUEUE_E_TABLE'

Two records with same key (Infocube)

Hi,
I was trying to do, in a update rule, an "IF" condition with two key figures.
IF Kf1 > Kf2. result = Kf1 else result = Kf2.
But the data in the source (datamart Infocube to infocube) have tow records with the same characteristics combination (the same keys)and different amount in the keyfigures, then the result of my "if" condition is not the expected because I understood in the infocube only exists one characteristics combination. :S
I was seeing those records in the manage transaction of the infocube.
Some reason for this?
Thanks and regards
Victoria Leó

This can happen with parallel loads. Two rows with same set of Char values but in different packets of the same Request, being loaded at the same time.
It really shouldn't be an issue - your update rule will make the KF change as desired. Your queries aggregate KFs based characteristic values, not Dim IDs, so you'll get the totals you expect.
Here's some more info:
There is an RSRV Test that lets you check a dimension for a cube to see if multiple DIM IDs exist for the same combination of Chars - Multiple Entries in Dimensions of a (Basis) InfoCube
Output looks like:
12:02:24 o'clock on 08/25/2006: Start test run for user PIZZAMAN:)
Dimension ZFM_C521: DIMID 61,215 and 61,214 have same characteristic values
Dimension ZFM_C521: DIMID 61,880 and 61,879 have same characteristic values
Dimension ZFM_C521: DIMID 61,366 and 61,365 have same characteristic values
Dimension ZFM_C521: DIMID 61,368 and 61,367 have same characteristic values
12:02:24 on 08/25/2006: Test run for user PIZZAMAN:) completed
You can run the Correct Error option to have it update fact rows to use one of the DimIDs if you want, but unless you have lots of them, I even wouldn't bother.
Here's the description of the test:
Description
This elementary test recognizes whether there are several lines that have different DIMIDs(dimension table key), but have the same SIDs for the selected dimension table for the InfoCube specified. (This can occur by using parallel loading jobs). This has nothing to do with an inconsistency. However, unnecessary storage space is occupied in the database.
Repairs
Since the different DIMIDs with the same SIDs are normally used in the fact tables, they cannot simply be deleted. Therefore, all of the different DIMIDS in the fact tables are replaced by one DIMID that is randomly selected from the equivalent ones. Before a change can be made to the database, the consent of the user is requested.
DIMIDs that have become unnecessary are deleted in the connection. In doing so, not only are the DIMDs deleted that were released in the first part of the repair, but so are all of those that are no longer used in the fact tables (including aggregates). The consent of the user is again requested before this change is made.

Create with duplicate key throws BaseEJBException instead of DuplicateKeyEx

WAS640 SP9: implemented an entity EJB, with a primary key field that is a String. The database table has the mapped column as a key. create(keyfield) works fine (I can get the data out with either sqlcli or through the EJB). If I try to add a 2nd bean with the same primary key, I don't get the javax.ejb.DuplicateKeyException that I would expect, I get get a com.sap.engine.services.ejb.exceptions.BaseEJBException (trace at end of message)
Any idea what I am doing incorrectly?

Hi Douglas,
The answer is that the EJB container does not have to throw DuplicateKeyException in case of an attempt for creating an already existing entity object. The EJB 2.0 specification, chapter 10.5.3 says "The container may, but is not required to, throw the DuplicateKeyException on the Bean Providers attempt to create an entity object with a duplicate primary key[15]." And the explanation follows in the footnote "[15] Containers using optimistic caching strategies, for example, may rollback the transaction at a later point."
In fact this is what happens in your case the EJB container postpones the insert database operation for the end of the transaction, thus optimizing the number of database access calls. Then, the primary key constraint violation is detected by the database, which leads to transaction rollback, but nevertheless an exception different from DuplicateKeyException is thrown.
The EJB container can detect primary key constraint violation in case two entities with the same primary keys are created in one transaction and then to throw the DuplicateKeyException (you can check this).
The conclusion is that EJB applications cannot rely on the DuplicateKeyException to distinguish the case when primary key constraint is violated. The EJB container can improve the primary key constraint violation handling by introducing an additional option for immediately storing a newly created entity object, thus checking whether an entity with the same primary key already exists and throwing DuplicateKeyException. This option will be introduced with the next versions of the EJB container, but nevertheless it again does not cover all possible scenarios. So my advice is simply to not rely on the DuplicateKeyException to distinguish primary key constraint violation from other transaction failures.

Read statement with duplicate key fields

Hello,
I have an internal table(EKBE) with 8 fields
ebeln ebelp vgabe gjahr belnr budat wrbtr refkey
populating the first 7 fields from EKBE table with VGABE = 2 and PO#, concatenating the WRBTR and GJAHR to get the Refkey and passing this to the 8th field.
Using this refkey, getting the document numbers from BKPF.
I am looping another internal table into a work area and reading the above internal table by passing the ebeln field and I am doing some calculations ,etc.
A custom table is getting updated from the above work area.
The issue is-
The internal table EKBE can have the same PO numbers with the same line item numbers but with different ref key's.
So, when I am reading the int. tab, it is reading only one record, since I have no other key's to read except EBELN. So for one PO# it is reading only 1 ref key, I cannot use the line item# as a key, as the line item#'s never match, even if they match they could be same PO# with same line item# and different ref key.
Any inputs highly appreciated.
Regards,
Kiran

Loop on EKBE Internal table as well to fetch all entries of PO. Use Parallel cursor to optmize performance.

Help selecting from records with duplicate fields

Test_table2 is shown below with the sql to create it.
I need to:
     Identify duplicate address_keys
        Within that set of duplicate address_keys, select only if HH_Income is the same between the two records and the HH_Age difference is less than 10
           Now the duplicate set matches the necessary criteria, and I want to select from these duplicate address_keys, only the one with the most recent verification date
The purpose of this is to infer cohabiting couples. In the large set of data we receive, for each HH_key if the people have the same last name they are all listed under the same HH_Key, but if they do not have same last name but live together, they will be listed as separate households (HH_key) but with the same address_key. A further validator is if each HH_key reports the same HH_Income and if they are close in age. We then only want to mail to one of the people, so we choose the one that has the most recent verification date.
The result I would expect here, using the table I provided, would be
HH_Key
Address_Key
HH_Type
HH_Income
Age
Verification_Date
1234
1111
10

50
10-Jun-13

I really like the results this gave, because it allows me to create a view now that contains the pair in one record. Thanks for this response. I think I did post the result that I was looking for which would be the one record that we would mail to: Once I create the view with one record for each pair, then I would just need to select the verification date that was greatest with the related data. Would that be the best approach to take? The fact that I now have a single record for each pair is excellent!
The result I would expect here, using the table I provided, would be
HH_Key
Address_Key
HH_Type
HH_Income

SM30 - Deleting a record with Foriegn Key Constraints

I have a two custom tables ZCCED_STATUS and ZCCED_COSTITEM.
ZCCED_COSTITEM has a status column with a foriegn key to a (PK) status record in ZCCED_STATUS.
I have generated table maintenance objects for the table ZCCED_STATUS.
When I go to SM30 and maintain the table ZCCED_STATUS I can select a status record and delete it. (still ZCCED_COSTITEM records using that status)
Is there any way that SM30 can warn or stop a user from deleting a ZCCED_STATUS record when there are child records in the ZCCED_COSTITEM table?
Regards,

Create a maintenance view , link both tables and generate a table maintenance for the maintenance view . it will work.

Updated with OS

seems like oracle .NET bindings doesnt work for new CLR . It works fine with .NET 2.0
May be Oracle folks will release new version for 4.0
