ABAP Routine to remove duplicates

Hello Experts,
I am beginner in SAP-BI. Need your help in writing ABAP Routine to get latest values for the combination
My Scenario:
I have a Custom DataSource built on only one table in ECC which consists Year, Vendor, Rate,Category etc. However in my DataSource only Year and Vendor are primary keys. I have to filter values for Year+Vendor where in if there are more than one combination exists for Year+ Vendor i sholud only consider the latest year values.
Example: Existing Values in DataSource (Duplicates vendors with respect to years)
Year
Vendor
2008
101
2009
102
2010
102
2011
101
2011
104
Desired Results:
Header 1
Header 2
2010
102
2011
101
2011
104
Ideally i need to have latest values of Year+Vendor combination. Could you please let me know what type of code/logic i need to implement to have this in place. Also please suggest me where i need to write the code...
Thanks,
Srikanth

Hi Pitchika Srikanth,
I know it's done. But I want to improve this code.
I worked on it.I maintained year and vendor as primary key in DSO. I loaded records as you loaded and did End Routine at transformation level.
Code: sort RESULT_PACKAGE by CALYEAR /BIC/ZCUST4 .
delete RESULT_PACKAGE FROM 1 to 2.
So My Output is:
Year
Vendor
2010
102
2011
101
2011
104

ABAP Routine to duplicate data

Dear Experts:
I need to duplicate data in a cube, changing the time characteristics. Can I do this with an ABAP Routine. This duplication has to be done each time the infopackage is executed. If this is posible, where should I write this routine? In the Start Routine of the Update Rules of the cube? or in the Update Rules inside the time characteristics?
Thanks in advance.
Pablo.

So something has gone bump somewhere inthe Export DataSource creation. The cube name ZBALANCE should not be an issue.
One thing that might be an cause, although I think you get a message about it is a missing Factview when you try to run the InfoPkg, but it's worth a look. Each cube should have a Factview created. It is a union view of both the F and E fact tables. Normally, the export datasource uses this view to extract tdata form the cube.
In SE12, search Views to see if you have the FactView - /BIC/VZBALANCEF. If you are missing it, search OSS notes on "Missing Factview". There is a pgm you can run - SAP_FACTVIEWS_RECREATE that recreates all teh Factviews.

Delete Overlapping Requests - by Filename via ABAP Routine

Hi SDN Community
Do you know if it is possible to set the delete overlapping request parameters to recoginse the file name, and remove it via the derivation of the file name via an ABAP Routine.
I am using an ABAP routine to derive the flat flat file upon loading, but do not know the syntax, or if it is possible to set this equivalent code into the delete overlapping request Routine area
(The code basically derives the first day of the calendar week, for previous weeks in the Do n times Loop

ABAP Routine for 0FISCPER slect options in InfoPackage

Hi,
I am trying to write an ABAP Routine for 0FISCPER as select options (range) dynamically.
Ex:
0FISCPER selection for this year as 001.2008 to 012.2008
0FISCPER selection for next year as 001.2009 to 012.2009.
Now we are changing InfoPackage every year manually, so I need to write a routine for 0FISCPER in InfoPackage to handle dynamically every year
Thanks,
SK.

Hi
write an ABAP routine to get that value..But are you getting any planned data(why you want till end of the year...till infopackage runs is o.k i think, if you don't have planned data)...Any way you can check the below code, which can be useful...
You can see the below code at->your infopackage selections>Ty-->choose variable type as 6 and enter any ABAP routine name( to create) and then there is a button on the application tool bar called 'routine info'..this give you the following information...
Definition
You can define complex selections for InfoPackages and control the automatic deletion of requests from InfoCubes in the scheduler, by using routines.
Routines are processing blocks in ABAP programs that consist of a pre-defined data declaration section and an ABAP subroutine (form routine). In the subroutine you can use all of the ABAP programming functions.
You can use the following routines for making selections in InfoPackages:
1. Selection routines for fields, on the Data Selection tab page
2. Selection routines for file names, on the External Data tab page
3. Selection Routines for selecting the from and to dates for time-dependent data, on tab page Update
4. Selection routines for determining old requests to be deleted after successfully loading a new request, on the Data Target tab page
Program frame:
After you have called up the Editor for routine maintenance, you get the following program frame:
1. Selection routines for fields, on tab page Data Selection:
program conversion_routine.
'$*$ begin of global - insert your declaration only below this line -
TABLES: ...
DATA:   ...
$$ end of global - insert your declaration only before this line    -
FORM COMPUTE_<Fieldname>
tables l_t_range structure rssdlrange
changing p_subrc like sy-subrc.
$$ begin of routine - insert your code only below this line       -
data: l_idx like sy-tabix.
        read table l_t_range with key
             fieldname = <Fieldname>.
        l_idx = sy-tabix.
        modify l_t_range index l_idx.
        p_subrc = 0.
$$ end of routine - insert your code only before this line       -
ENDFORM.
2. Selection routines for file names, on tabstrip External Data:
FORM compute_flat_file_filename
     changing p_filename like rsldpsel-filename
          p_subrc like sy-subrc.
$$ begin of routine - insert your code only below this line-
          p_filename =
          p_subrc = 0.
$$ end of routine - insert your code only before this line-
ENDFORM.
3. Selection routines for selecting the from and to date for time-dependent data, on tabstrip Update:
form compute_time_dependent_dates
     changing p_datefrom type d
              p_dateto   type d
           p_subrc like sy-subrc.
$$ begin of routine - insert your code only below this line-
          p_datefrom =
          p_dateto   =
          p_subrc = 0.
$$ end of routine - insert your code only before this line-
ENDFORM.
4. Routines for determining the old requests to be deleted after successfully loading a new request, on tab page Data Targets:
form compute_<InfoCube-Name>
tables l_t_request_to_delete structure rsreqdelstruc
using l_request like rsreqdone-rnr
changing p_subrc like sy-subrc.
*Insert Source Code to decide if requests should be deleted.
*All Requests in table l_t_request_to_delete will be deleted
*from Infocube <InfoCube-Name>.
*Add new requests if you want to delete more (from this cube).
*Remove requests you did not want to be deleted.
$$ begin of routine - insert your code only below this line-
     loop at l_t_request_to_delete.
     endloop.
     clear p_subrc.
$$ end of routine - insert your code only before this line-
ENDFORM.
Note:
Those fields flagged with <...> are dependent on the selection fields and are filled automatically by the system when you call up the Editor.
Procedure
Make the following entries:
1. Between $$ begin of global ... and $$ end of global ... you can define data declarations. These are the declaration sections for the local data in the routine. This data is only visible in the routines.
2. The subroutines begin with FORM and end with ENDFORM.
The subroutines for the particular routines are:
Selection routines for fields on tab page Data Selection: FORM COMPUTE_<Field name>
Selection routines for file names on tab page External Data : FORM compute_flat_file_filename
Selection routines for selecting the from and to dates for time-dependent data on tab page Update: FORM compute_time_dependent_dates
Routines for determining old requests to be deleted after successfully loading a new request on tab page Data Target: FORM COMPUTE_<InfoCube-Name>
The subprograms have the following parameters:
Subprogram FORM COMPUTE_<Field name>:
l_t_range
In the table l_t_range the routines for all selection fields that are filled, or have a routine, are made available.
The routines are executed in the scheduler last of all and therefore, you can change all the selections that you have carried out previously.
p_subrc
Using the variable p_subrc you can report errors to the scheduler. p_subrc <> 0 signals an error and means the data request is terminated.
Subprogram FORM compute_flat_file_filename:
p_filename:
You give the name of the file that is to be loaded in parameter p_filename.
This is useful if your file name contains date dependencies that should be determined by sy-datum and calculated during runtime.
p_subrc
You can inform the scheduler of an error with variable p_subrc. p_subrc <> 0 signals an error and means that the data request is terminated.
Subprogram FORM compute_time_dependent_dates:
p_datefrom and p_dateto
Fill these parameters with the from and to dates for time-dependent master data and texts.
p_subrc
You can inform the scheduler about an error using variable >LS>p_subrc. p_subrc <> 0 signals an error and means the data request is terminated.
Subprogram FORM COMPUTE_<InfoCube-Name>:
l_t_request_to_delete
You give the request number of the request that is to be deleted in parameter l_t_request_to_delete. You can also delete requests from the table. These are then not deleted.
p_subrc
You can inform the scheduler about an error with the variable p_subrc. p_subrc signals an error and means the data request is terminated.
3. Insert your program code for the routines between $$ begin of routine ... and $$ end of routine ... so that the respective subprogram variables are supplied with the corresponding values.
4. Check the syntax of your routine with the Check function.
5. You can then transfer the routine with the Save function.
You end routine maintenance when you exit the Editor.
Hope it helps
Thanks,
Teja

ABAP / Query to Identify Duplicate Rows in Cube

Dear Experts,
We have a situation were some of our Cubes (due to compression and varying levels of forceful reloads) now contain duplicate rows.
What I need to know is :-
1) Is there a way to identify duplicate rows where one of the characteristics are different but all key figures are identical.
2) If so what is easier to achieve, ABAP routine/program or Query
3) If ABAP suggestions on how to code such
4) If query same.
What I need it to do is tell me which ClaimNo record (Primary Key) has duplicates and what characteristic has caused it.
I know I am asking for a lot but I really need to get this resolved as it's causing mayhem and trying to pinpoint these records is both time consuming and painful. What we are looking to do with the records is establish how they became duplicated so we can prevent this happening in the future.
Your help as always much appreciated.
Regards
Craig

Hi Craig,
My previous answer can find out what all cubes and data targets have been loaded based on a request.
Actually for your query. The following information will be surely useful.
tables: /BIC/**(source ) , /BIC**(target)
parameter : fieldname like /BIC/****-fieldname ( In ur case the it can be primary key or Duplicate entry )
data: itab_source like /BIC/*** occurs 0 with header line,
      itab_destination like /BIC/*** occurs 0 with header line.
data: wa_itab_destination like line of itab_destination.
select *
from /BIC/*****
into corresponding fields of table itab_source.
where fieldname = fieldname.
******Include your piece of code which is for deleting records
Delete adjacent duplicates from itab_source comparing characteristic ( i.e duplicate characteristic you specified)
****Use this to delete the ODS Data before writing into it
call function 'RSDRI_ODSO_DELETE_RFC'
exporting
    i_odsobject = 'ODS Name'
    i_delete_all = 'X'.
if sy-subrc = 0.
loop at itab_source.
    move-corresponding itab_source to itab_destination.
    append itab_destination.
endloop.
modify /BIC/*** from table itab_destination[].   target being written from itab.
commit work.
endif.
Please Reward points if this helps really.
Thanks,

Best app to remove duplicates from iTunes 2014

Hi All,
I've been trying to research the best application to sort and remove duplicates from my iTunes library. I have over 7000 songs and iTunes built in duplicate finder doesn't look at the track fingerprint, which is useful for those songs which are labelled "Track_1" etc.
Has anyone reviewed any recent products? I was looking at TuneUp, but after reading so many negative comments, I've decided not to go down that path. I would prefer a program that did most of the work for me, due to the amount of songs. Happy to pay for a good product...
I do have MusicBrainz Picard, which has done a great job of tagging, but don't remove duplicates.
Thanks in advance :-)

Tune up is a great app. When they moved from version 2 to version 3 is when it went to crap and all heck broke loose. They shut their doors but they have since re opened and went back to developing version 2. I use that version and I am pretty happy with it as being an overall cleanup utility. I also use Musicbrainz and a couple of other utilities but in the end if you have an enormous library 20k plus then you are going to have a few slip through. I would probably go with Tuneup if I were you and a thorough third party duplicate finder. Dupe Guru's music edition seems to do a pretty good job.

Removing duplicate values from selectOneChoice bound to List Iterator

I'm trying to remove duplicate values from a selectOneChoice that i have. The component binds back to a List Iterator on the pageDefinition.
I have a table on a JSF page with 5 columns; the table is bound to a method iterator on the pageDef. Then above the table, there are 5 separate selectOneChoice components each one of which is bound to the result set of the table's iterator. So this means that each selectOneChoice only contains vales corresponding to the columns in the table which it represents.
The selectOneChoice components are part of a search facility and allow the user to select values from them and restrict the results that are returned. The concept is fine and i works. However if i have repeating values in the selectOneChoice (which is inevitable given its bound to the table column result set), then i need to remove them. I can remove null values or empty strings using expression language in the rendered attribute as shown:
<af:forEach var="item"
items="#{bindings.XXXX.items}">
<af:selectItem label="#{item.label}" value="#{item.label}"
rendered="#{item.label != ''}"/>
</af:forEach>
But i dont know how i can remove duplicate values easily. I know i can programatically do it in a backing bean etc.... but i want to know if there is perhaps some EL that might do it or another setting that ADF gives which can overcome this.
Any help would be appreciated.
Kind Regards

Hi,
It'll be little difficult removing duplicates and keeping the context as it is with exixting standard functions. Removing duplicates irrespective of context changes, we can do with available functions. Please try with this UDF code which may help you...
source>sort>UDF-->Target
execution type of UDF is Allvalues of a context.
public void UDF(String[] var1, ResultList result, Container container) throws StreamTransformationException{
ArrayList aList = new ArrayList();
aList.add(var1(0));
result.addValue(var1(0));
for(int i=1; i<var1.length; i++){
if(aList.contains(var1(i)))
continue;
else{
aList.add(var1(i));
result.addValue(var1(i));

Populate new fields in DSO (DBTable) with ABAP routine

Hi,
I've added a couple of fields to a DSO. The DSO contains a large number of records (60m+) and I have a tight window to cutover so the activation time would be an issue if I use a loop transformation. Therefore, I am looking to populate the additional fields directly in the Active table using an ABAP routine.
One of the fields is a key figure to be derived from an existing CHAR field so would need to apply some logic during update, such as IF <CHAR_FIELD> CA 'ABC'. <KYF_FIELD> = 1 etc.
Aside from fairly basic Start Routines my ABAP is very poor so was wondering if anyone can help me with the syntax or, preferably some sample code to achieve this.
Thanks in advance,
Ad

Hi,
   In transformation of the cube, choose routine for char E.
   There you can assign value in RESULT field. Actually RESULT field is assigned to E, find the code below,
*-- fill table "MONITOR" with values of structure "MONITOR_REC"
*-   to make monitor entries
... "to cancel the update process
   raise exception type CX_RSROUT_ABORT.
... "to skip a record
   raise exception type CX_RSROUT_SKIP_RECORD.
... "to clear target fields
   raise exception type CX_RSROUT_SKIP_VAL.
(* insert your abap code here to find the value of E*.)
     RESULT =                     * assign the value you got for E here.
rgrs,

How to remove duplicate items ?

ok so ive moved my iTunes library from the NAS drive I bought (after finding out that wouldnt work) onto my new laCie external drive, but ive found some of my albums have triple copies?
i know how to show duplicates but im not sure how to safely remove duplicates without deleting all copies?

Oh boy.
I'm sure there are better ways to do it than this and it will take time, but to avoid all possible loss of data, what I would do is first consolidate all of your libraries.
• Open the iTunes Library you think is most correct by holding down the OPTION key when you open the iTunes application, which should bring up a dialogue like this: http://cl.ly/image/2i2Q3o0Z0Y3C
• Then go to preferences and make sure it looks like this: http://cl.ly/image/2C2Z0u0C3T3c
I would recommend keeping your main iTunes library on your main hard drive (for me that's my internal), unless you definitely can't fit it.
• Now go to the File menu >Library > Import Playlist
• Navigate to another of the libraries, and click on the iTunes Library.xml file and import it. Do this for each of your libraries, except the one you are currently using.
• Now that you've got everything imported into the one library, the fun part starts.
Do what i said in my previous post and remove all the duplicates.
• Once that's done, check all the other libraries to make sure you haven't missed anything, and send them on their way to the Trash, and empty it to reclaim all that space.
I really hope you get this sorted, I went through an ordeal like this myself recently, so it's going to take time, but it feels good when it's all cleaned up and finished!

PS. After writing all this I thought, hmm, why didn't I just Google it instead of figuring it out myself? ;P
I found this, and it might help if my instructions weren't clear enough. https://bitly.com/LpqFPq

How to remove duplicate POP messages in Mail under Mavericks

Hello
I'm having some significant problems with Apple Mail, and despite having researched widely, I haven't been able to find a solution yet. Here is my tale of woe...
My set up is that I use Mail with 5 separate accounts, downloading all messages using POP. I keep ALL my mail (even the trash) so that I have a permanent record of all conversations, going back more than 10 years - this is about 250,000 emails in around 250 subfolders. I'm running the latest version of Mavericks on a 2010 MBP. I have no intention of moving to IMAP - I need to keep a local archive of all my mail.
A few months ago I was having problems with Mail being very slow to load and search emails. I decided to rebuild the mailboxes, but afterwards discovered that thousands of messages in the inbox of one of my accounts (and some of the sub-folders) had disappeared. Once I realised I tried to go back to a recent Time Machine back up, but, for whatever reason, that part of the back up hadn't worked properly and I was unable to recover the previous status. I left it while I decided what to do, and had time to deal with it...
The last 2 years worth of emails on that account were still archived on gmail, so last week I decided to try redownloading the whole lot (something like 72,000 messages), and then planned to use one of the scripts I was aware of to remove the duplicates to the trash, and then remove any duplicates in the trash forever. That ought to mean I at least had an archive of the last two years of missing messages, even if I had no record of which ones had been flagged or replied to, etc.
The downloading took about 24 hours to complete, and I now have almost 70,000 messages in the inbox of that account. I also rebuilt all the folders again, which doesn't seem to have resulted in any further loss of messages as far as I can tell. However, I hadn't figured on two things:
1. Mail 'hides' duplicate messages, meaning that all of the messages I've downloaded are showing as unread, and I can't differentiate the ones I already had in my Inbox, and the new downloads. When I click on those apparently unread messages I can see if they have been replied to or forwarded, etc, but there's no obvious way for me to remove the ones I have already dealt with to the trash, without going through them all manually, which is clearly impossible.
2. The scripts I'd found for removing duplicates don't work. Andreas Amann's Remove Duplicates script doesn't work under Mavericks, and he has abandoned the project. I've also tried the remove-duplicate-messages.scpt made by Jolly Roger (http://jollyroger.kicks-***.org/software/), and while it *sometimes* works on individual subfolders on my Mac (but as far as I can tell removes the duplicate in that folder, rather than the newly downloaded version), mostly it doesn't work at all - it creates a 'Remove Duplicate Messages' folder on my desktop, a log inside it and a folder for removed messages, but nothing appears in the duplicates folder.
So, I'm left in a position where I have 70,000 apparently unread messages in my Inbox, a massively bloated Mail library (which has pretty much doubled in size, because of the 'hidden' messages), a slow and unresponsive Mail program. I've come to the conclusion that there must be some corrupted email somewhere, which probably caused the original email haemorrhage, and may still be causing the inability to remove duplicates. Mail is so slow as to be almost unuseable.
I figure I have a number of options:
1. I could live with the situation and just archive most of the Mail in my inbox, with the side effect that there will be a bunch of messages I have never replied to that are missed.
2. I could abandon the last week's efforts and revert to the version of Mail I was using a week ago, and then redownload the recent emails from my various accounts. That would still leave me without those thousands of emails I lost on my local machine.
3. I could find another way to deal with this. Can I get the remove duplicates script working? Should I revert to the version of Mail from a week ago, download ALL the messages again, but do it in a way that allows me to find the duplicates and remove them? Should I move to another email program altogether (which would presumably be massively disruptive to my work!)
Anyway, apologies for the essay length of this request, and thanks in advance for any help you may be able to offer!

hi Eric
thanks for the tip, but I don't think that solves my problem, which is that Mail apparently hides the duplicates, so they're still there, you just can't differentiate or remove them. I actually *need* the duplicates there so I know I've got everything, but then I need to be able to move the ones I know I've dealt with from my inbox to an archive/trash, and/or remove them completely so Mail isn't totally bloated

I have more than one photo backup on my computer now itunes has downloaded three of each photo. How do I remove duplicates

I have more than one photo backup on my computer now itunes has downloaded three of each photo. How do I remove duplicates?

Wich version of iPhoto do you have? You need iPhoto '09 or '11 to order prints.
Make an album of all photos you want to order in the same order.
Then select all photos at once, when you use Share > order prints.
You should see a panel like this, where you can mark the quantities. The screenshot is from iPhoto 9.6:

HT2905 how do you remove duplicate libraries from itunes

I recently purchased a new window9.1 computer. I tried to move the library to the new pc by using an external haddrive. The songs and other items all transfered, but the mudic remsined on the externalmedia informaiton files, I had to connect the drive to listen to music.. I worked with tech support and copied themusioc files to ITunes. When I reopened the media files and copied music were on the system. ITunes recognzed there was missing information on the media data file and corrected it, so oe I have 20,000 sonfs in a 10,000 song library.How do you delete massive duplicates without individually deleting10,000 songs?

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.
(If you don't see the menu bar press ALT to show it temporarily or CTRL+B to keep it displayed)

How to remove duplicate songs from Itunes

I've consolidates my music in Itunes 11.01. Playlists are just getting crazy with duplicates.
I want to eliminate duplicate music files, as well as eliminate the references in the interface.
Then sync my new IPad.
When I manually erase a duplicate in Windows Explorer, I'm left with a "!" indication in Itunes that the file cannot be found... duh.
I want to find either an easier way to eliminate duplicates without Windows Explorer, or
a way to select all the "!" references in Itunes interface and delete.
Help please from a completely organized person who hates Apples "intelligence" at thinking it knows what I want, and not providing
adequate help under "remove duplicates" in its help index.
Thanks.

I would do it manually. As you can see from turingtest2's post, some duplicates are not really duplicates.
I would also review how you add media to iTunes. It should not be producing all that many duplicates.
