How to delete the duplicate requests in a cube after compression.

Hi experts,
1. How to delete the duplicate requests in a cube after compression.?
2. How to show a charaterstics and a keyfigure side by side in a bex query output?
Regards,
Nishuv.

Hi,
You cannot delete the request as its compressed as all the data would have been moved to E table ..
If you have the double records you may use the selective deletion .

Deleting the duplicate records

Hi all,
I have some duplicate records in the PSA . and i want to delete the duplicate records before the data is entered into the data target. Can anybody tell me how to achieve this.
Actually i need to achieve this by using the ABAP code.
Thanx & Regards,
RaviChandra
Edited by: Ravichandra.bi on Mar 5, 2012 3:37 PM

Hi Ravi,
If its a full load to the PSA and because of it you are getting duplicate records and you want to eliminate them,
you can do what Anshul and Durgesh suggested.
Write the code in the start routine of the transformation to your target
SORT SOURCE_PACKAGE BY KEY1 KEY2 KEY3. "(The key will be the key of your target)
DELETE ADJACENT DUPLICATES FROM SOURCE_PACKAGE
COMPARING KEY1 KEY2 KEY3.
Hope this helps

How to delete the duplicate email address in BP master data

In CRM you can create the same BP with different id. I would like to know how to delete the email address during importing email addresses from the third party tool.
During the campaign you are sending email to all your customers, when the customer want to unsubscibe the email address from your list, how to unsubcribe the email address and how to updat the BP master data.
If you are sending the email to customer, you are using html or simple text, if the customer wants only html or simple text, how you to specify in the system?
thanks,
arul

Hello Arul,
welcome to the SDN CRM Development forum.
1. I think you should clear the data with duplicate E-Mail adresses in the external tool.
2. Unsubscription could be done by a Marketing Attribute which could be set by using a Target Group which is created by Campaign Automation. Have a look at this Toppic. There is also a Best Practice avaliable at http://help.sap.com/bp_crmv340/CRM_DE/index.htm.
3. Also HTML or Simple text can be mained in a Marketing Attribute. You have to use different Mail Forms to which are sent to different Target groups.

Not sure if there is an automated way to do this, but I get around it by just searching on (2), (3), (4).
Not practical for large installs, but it works in our small environment.
You might be able to use the Smart Sort utility to find files that have () characters in them? Not positive though.
It would make a great enhancement request to add dupes to either a log file or better yet an admin utility to track the living documents to ensure they are fixed!
(I'm going to file such an enhancement right now!)

HT2905 Most all of my 1700 songs have been duplicated in iTunes. I have downloaded the instructions how to delete the duplicates but it says "sort by the date you added" and i have no column that says that. I am running windows xp.

Most all of my 1700 songs have been duplicated in iTunes. I have downloaded the instructions how to delete the duplicates but it says "sort by the date you added" and i have no column that says that. I am running windows xp.

Apple's official advice is here... HT2905 - How to find and remove duplicate items in your iTunes library. It is a manual process and the article fails to explain some of the potential pitfalls.
Use Shift > View > Show Exact Duplicate Items to display duplicates as this is normally a more useful selection. You need to manually select all but one of each group to remove. Sorting the list by Date Added may make it easier to select the appropriate tracks, however this works best when performed immediately after the dupes have been created. If you have multiple entries in iTunes connected to the same file on the hard drive then don't send to the recycle bin.
Use my DeDuper script if you're not sure, don't want to do it by hand, or want to preserve ratings, play counts and playlist membership. See this thread for background and please take note of the warning to backup your library before deduping.

How to retrieve the duplicates records.

Hi friends,
My next issue, how to retrieve the duplicate records in web intelligence.I checked the option Retrieve duplicate records in web intelligence as well.But it is not helping me.
Hope you guys are help to solve this issue.
Thanks lot,
Regards,
-B-

hi Blaji,,
ive tried this here and it worked perfectly with me
even so, you dont need to make the QTY as a dimension, you can leave it as a measure also, and it will work good with you.
click the block on the WebI, the Block itself.
and find its properties, under "Display", you will find
"Avoid Duplicate row Aggregations"
in the query it self you should flag "Retrieve Duplicated Rows"
i think this will work fine with you
good luck

HOW MANY INTERFACES AND PROCEDURES SHOULD BE CREATE? WHAT ARE THEY?
HOW TO REACH MY REQUIREMNT?
Answer provider is more appricatable.
Thanks in advance.
Edited by: krishna on Nov 9, 2011 8:40 PM

1st option
See in this scenario you can use two interface and one procedure step.
1st interface-->poricedure-->2nd interface
1st interface will bring data to oracle staging-->then procedure will delete matched record from target using keys--->3rd interface will simple insert the the data in oracle staging.
2nd option
Insted of deleting the target matched records, you just update target matched record with latest records in your staging oracle.You can use IKM Merge

Delete the parent records and child table records at a time

hi all;
I am facing the pbm like to delete the all records in child table and corresponding records in parent table at a time. so I want to delete the all the records in child table and corresponding parent records in parent table by using single SQL query. plz help me
Thanks in advance

You want to use one single SQL statement to delete the child records in a table and the corresponding master records in the master table??
That's not quite possible with a single SQL, of course unless you are talking about Oracle Forms, where you have a relation and set the delete behavior to Cascading, like said in the above posts.

How to delete the last element of a collection without iterating it?

how to delete the last element of a collection without iterating it?

To add to jverd's reply, even if you could determine the last element, in some collections it is not guaranteed to always be the same.
From HashSet:
It makes no guarantees as to the iteration order of the set; in particular, it does not guarantee that the order will remain constant over time.

How to delete the double records connected to one or more than one tables in SQL 2008?

Hi
Can anyone please help me with the SQL query. I Im having a table called People with columns names: personno., lastname, firstname and so on. The personno. is having duplicate records,so all the duplicate records i have written with "double" in
the beginning of the numbers. I tried deleting these double records but they are linked to one or more than one tables. I have to find out, all the tables blocking the deleting of double person. And then create select statements which creates update statements
in order to replace the current id of double person with substitute id. (The personno. is in the form of id's in the database)
Thanks

You should not append "double" in the personno. When we append it will not be able to join or relate to other table. Keep the id as it is and use another field(STATUS) to mark as duplicate. Also we will require another field(PRIMARYID) against
those duplicate rows i.e the main or the primary personno.
SELECT * FROM OtherTable a INNER JOIN
(SELECT personno, status, primaryid FROM PEOPLE WHERE status = 'Duplicate') b
ON a.personno = b.personno
UPDATE OtherTable SET personno = b.primaryid
FROM OtherTable a INNER JOIN
(SELECT personno, status, primaryid FROM PEOPLE WHERE status = 'Duplicate') b
ON a.personno = b.personno
NOTE: Please take backup before applying the query. This is not tested.

How to delete the single record from the ODS

HI,
I want to DELETE the particular record from ODS.. how to delete that..
plz give me the solution.. it's urgent..
with regards
@jay

Hi Prakash,
You can delete a particular record from ODS by specifying the key field name in Selective deletion button available in Contents tab in the manage screen of ODS. But it will only delete the record from the active data table and not from the Change log and new data table . You should be very carefull if you are doing in Production system as there is chance of deleting other records accidentally.
Go to Selective deletion button - > Click on delete selection -> Enter the key field values of the record you want to delete-> Press save button to save as Variant -> Go back and click on selection button -> Chosse the background job type -> Click on start button.

Prakash
