Delta Update Differences in LO

Hi,
What is the difference between DIRECT, QUEUED AND UNSERIALIZED V3 updates and how and when do we choose a specific type of delta type against the other.
Thanks

What is the difference between qued delta update and serialized delta upda

what is the difference between qued delta update and serialized delta update?

Hi Ks Reddy,
Queued Delta:
In case of Queued delta LUW's are posted to Extractor Queue (LBWQ), by scheduling the V3 job we move the documents from Extractor queue to Delta Queue(i.e. RSA7) and we extract the LUW's from Delta Queue to BW side by running Delta Loads. Generally we prefer Queued Delta as it maintain the Extractor Log which us to handle the LUW's which are missed.
Direct Delta:
In case of Direct Delta LUW's are directly posted to Delta Queue(i.e. RSA7) and we extract the LUW's from Delta Queue to BW side by running Delta Loads. If we use Direct Delta it degrades the OLTP system performance because when LUW's are directly posted to Delta Queue (RSA7) the application is kept waiting untill all the enhancement code is executed.
Non-serialized V3 Update:With this update mode, the extraction data for the application considered is written as before into the update tables with the help of a V3 update module. They are kept there as long as the data is selected through an updating collective run and are processed. However, in contrast to the current default settings (serialized V3 update), the data in the updating collective run are thereby read without regard to sequence from the update tables and are transferred to the BW delta queue.

10.10.2 will not install - tried Mac App Store and Delta updater

I'm trying to install the 10.10.2 update on a 15" MacBook Pro (Mid 2010) which currently has 10.10.1 on it and its not going well!
The Mac App Store shows the 10.10.2 update, I click Update and dropdown says "Some updates need to finish downloading before they are installed. Your computer will restart to complete the updates." with the options "Not Now" and "Download & Restart". Doesn't matter which one I choose, after a click the update progress bar appears for a few seconds and then reverts back to displaying the Update button again. Have restarted, fixed permissions etc and it makes no difference.
So I downloaded the Delta update (not the combo) and go through the install steps and the system restarts to compete the installation, but the system simple restarts and does not update to 10.10.2, its still at 10.10.1. Have tried a few times, always the same.
One slightly odd issue is that the Apple remote Desktop update 3.8.2 appears to have been installed 5 times in the "Updates Installed in the Last 30 Days" section of the Mac App Store and yet it also still appears in the updates available section below the 10.10.2 update.
I've repaired permissions, restarted, checked Activity Monitor for any non responding services and checked disk space availability - 170GB available. Can't see anything obvious.
Anyone else having trouble installing this OS update?
Thanks

I have the exact same problem. Tried to install the normal and combo update. Nothing happens.
I tried the repair permissions and even the reset password method. Nothing.
Did the system restore help ? did you try to re-install yosemite first keeping your files and applications ?
It's really weird.
Thanks

Delta Initialization vs Delta Update

We're having some issues with performance when loading our GL cube. What I would like to do is perform many delta initializations, each delta inititialization containing one month/period.
My confusion is in the fact that the last time I attempted this, when I subsequently went to run my delta UPDATE the same selection criteria was automatically inserted into my delta update.
So for example my INIT may look like this;
REQUEST1: Selection = 001.2005
REQUEST2: Selection = 002.2005
etc........etc...
REQUEST12: Selection = 012.2005
Next the UPDATE info package seems to inherit the same criteria... doesn't this mean it will not update anything beyond that criteria??
I'm just wondering if it is possible to do an incremental initialization and still be able to enable delta updates for future periods?
Thanks!

Hi Patrick,
The delta update will load the data as per the selections made in the Init run. A delta requested after several initializations, contains the sum of all the successful initial selections as a selection condition. This selection condition can then no longer be changed for the delta.
Take a look here for more info:

Get back the Data mart status in ODS and activate the delta update.

I got a problem when deleting the requests in ODS.
actually there is Cube(1st level. it gets loaded from an ODS(2nd level). this gets loaded from 3 ODS'S( 3rd level). we were willing to delete recents requests from all the data tardets and reload from PSA. but while delting in the request in ODS(2nd level), it has displayed a window, showing as follows.
- the request 132185 already retrived by the data target BP4CLT612.
-Delta update in BP4CLT612 must be deactivated before deleting the request.
- Do you want to deactivate the delta update in data target BP4CLT612.
I have clicked on execute changes in the window. it has removed the data mart status for all the request which i have not deleted.
in the same it happened inthe 3 ODS's(3rd level).
I got clear that if we load further data from source system. it will load all the records from starting.
so to avoid this can any body help me how to reset the Data mart status and activate the delta update.

Hi Satish,
U have to make the requests RED in cube and back them out from cube,before u can go for request deletions from the base targets(from which cube gets data).
Then u have to reset data mart status for the requests in your 'L2 ODS' before u can delete requests from ODS.
Here I think u tried to delete without resetting data mart status which has upset the delta sequence.
To correct this..
To L2 ODS,do an init without data transfer from below 3 ODS's after removing init request from scheduler menu in init infopackage.
Do similar from L2 ODS to Cube.
then reconstruct the deleted request in ODS.It will not show the tick mark in ODS.Do delta load from ODS to Cube.
see below thread..
Urgentt !!! Help on reloading the data from the ODS to the Cube.
cheers,
Vishvesh

How can i correct a delta update?

Hi ALL,
i have a delta update in an InfoCube that is failed the 28/07/2007 the processing is a procedure to load data from yesterday (27/07/2007) (after that date all deltas was finished correctly) i don't have an error message, in the status tab of the monitor i have: short dump in the warehouse, diagnosis: The data update was not completed. A short dump has probably been logged in BW providing information about the error.
my problem is: there is a query bex based on a multicube that return no applicable data found and this cube is a part of the multicube.
when i click on the manage menu on the cube in the Requests tab on the second column i have: Request for Reporting Available and in this column i have the query sign that request is availble for reporting until the date where i have the failed delta load. (i don't know if there is the problem affected my query Bex)
one time i have seen somebody that was corrected a delta fail going in the monitor status tab clicking on the red light and after he set the set Overal Status to red (status not ok) but when you click save you get another popup ask you: set all updated requests in the ICs to this QM status?
i'm blocked in this step because i'm afraid to make a many troubles in the Cube and i don't know if i choose yes if it will affect all the requests after my failed delta request.
can Someone help me please???
Thanks in Avance
Bilal

Hi Amit,
1) the datatarget is being feed by one datasources.
2) after the RED request in the data target i have 5 green requests, they use PSA and update subsequently in Data targets, but when i have checked the PSA today
i see that i have only the data for yesterday and today.
i don't have reference in PSA for the load that have failed 28/07/2007
About the RED request:
1) i don't have reference in the PSA for that request
2) in the monitor of that request i have 661682 from 661682 Records
when i check the Header tab in the monitor i have the processing: From PSA into data targets and the update mode: Full update
when i click on the infopackage i have the processing tab: Only PSA and update subsequently in Data targets, the update tab is full update...i don't know why they give the name MA DELTA for the infopackage.
i have deleted the RED request and the system had put automatically the next green requests like available for reporting ....i execute the query in this time return data but without value for the june's months ...i don't know if i have make a mistake to delete the requests or no!!!
somebody have opinions
thanks Bilal

Delta Update in data Target Must be Deactivated Before deleting the request

Hi Experts,
I got an error while deleting a request from an ODS target. In breaf Let me explain..
Today one data load got failed. The data source 0CRM_SALES_CONT_I ( CRM Sales Contract : Item ) is updating data to 4 ( Four ) ODS targets.
So I forcefully made the request red to delete the request from the targets. But I unfortunately deleted another request without making it RED, I reconstructed it. Everything is looking fine.
   But the thing is , when I tried to Delete the ERROR request from the other two related Data Targets ( 0CRM_CN2P and   0CRM_CNT1) , I fount these warnings..
                --> Request 140522 already retrieved by Data Target BWPCLNT600
                --> Delta update in Data Target BWPCLNT600 must be DEACT. before deleting the request.
                --> Do you want to DEACTIVATE the Delta Update in the Data Target BWPCLNT600   ?
   I clicked on YES.
I am having doubt, will it make any problem in future ? Or How Can I Resolve this problem   ?
Thanks,
Utpal.

Hi shanthi bhaskar ,
Thank you. But the client no which I have mentioned is not our. That is different, I have given for the example. Bur the DS and ODS name are as it is.
   and Shanthi, Won't be any problem as I got the warning as mentioned above.. ?
Thanks,
Utpal

Problem with delta update on customised export data source.

Hi all BW gurus,
I have created several customised export data sources in the R/3 system. And I have made use of the utility program <Z_CHANGE_DELTA_PROCESS> to update the ROOSOURCE table.
While this can result in being able to do initial update (instead of full update), the subsuquent delta update is not working.
In RSA7, the datasource is with green light and in RSA3, the extractor can extractor data out of it.
Does anybody have some idea on this?
I heard that there is a way to change the Business Transaction Event (BTE), but I don't quite understand how this is performed. And wonder if this is the only way out. To me, the triggering point would be the same, meaning the InfoPackage would be executed, then call the extractors in R/3 to extract the delta update in order to load into the InfoCube.
And how do others do for executing delta update of the customised data source?
Thanks a lot!!
The utility program of <Z_CHANGE_DELTA_PROCESS>:
=================================================
report z_change_delta_process .
*P_DATAS DataSource
*P_DELTAP Delta Process for DataSource
parameters:
p_datas type roosource-oltpsource,
p_deltap type roosource-delta.
tables:
roosource.
data:
ls_roosource type roosource.
if p_datas(2) ne 'Z_'.
   message 'The DataSource needs to begin with ''Z_''.' type 'E'.
endif.
select single * from roosource into ls_roosource
       where oltpsource = p_datas
       and objvers = 'A'.
if sy-subrc eq 0.
   ls_roosource-delta = p_deltap.
   update roosource from ls_roosource.
message 'The DataSource has been updated successfully.' type 'I'.
else.
   message 'The DataSource entered is not valid, try again.' type 'E'.
endif.

Doesn't anyone have any idea on this topic?
Appreciate for all the help. Thanks.

How to Delta Update in Flat Files

Hi all,
I would like to know is delta update is supported in flat files ? If yes how does this work ..... is there a SAP white paper or document on this
Thanks
Nathan

Hi......
Yes Delta upload is supported by Flat files..........In this case........when the delta data records are loaded by flat file......... This delta type is only used is 'F'.......for DataSources for flat file source systems. Flat files are imported to the PSA when you execute the InfoPackage. The staging process then begins.........The delta queue is not used here.
As Siggi already told in the Following thread......post your flatfile data to an ods object with update mode overwrite. The ods object will do the delta for you then.........
Delta Upload for Flat File

WHEN WE GO FOR DELTA UPDATE WHAT HAPPENS IN R3 at same instant of time

hi all
when we go for delta update in bw at same time what the process takes place in R3

Delta queue in R/3 T code is rsa7, the data comes to these tables before it is pulled in to BW. Nothing really happens in R/3 when you do a delta extraction. The delta queue keeps getting refreshed with the data for your next delta update.
Thats my 2 cents

Deactivate delta update before deleting the request from ODS

Hi all,
Happy New Year wishes to all.
I have a scenario, where I am feeding the data to ODS from flat file and from ODS to Cube. Here ODS is a Data mart. Flat file to ODS full update and ODS to Cube First Initialization and Delta.
I deleted the latest request from ODS, at the I got the message dialog box and it is saying that
Request 98888 already retrieved by data target BWVCLNT
Delta update in data target BWVCLNT must be deactivate before deleting the request
Do you want to deactivate the delta update in data target BWVCLNT?
So I pressed Execute changes, then after I loaded the data in to ODS and when I am trying to load the data into Cube, once I pressed execute button it is displaying the message dialog box like
Delta request is incorrect REQXXXXXXX in the monitor
A repeat needs to be requested
Data target still include delta request REQXXXXX
If the repeat is now loaded, then after the load
There could be duplicate data in the data targets
Request the repeat?
After execute changes it is showing only zero Records only.
What is that mean and why zero records it is displaying instead of delta records.
Anybody faces this type of problem please let me know. This is somewhat urgent to me
Thanks and Regards
Satish Chowdary

<i>Hi Satish,
First Switch off the ODS ( automatic Update of Datatarget ) , though not really necessary. delete the Req from the Infocube, then delete from the ODS . Now delete the Init Req from the Infopackage for datamart infopackage.then Do an Init without datatransfer into Infocube. Later load data into ODS and then go for delta update to Infocube.
I hope this helps.
Thanks,
Krish

How to catch Delta Initialization and Delta Update in a Function Module

Hi Experts:
I'm developing a FM to extract data from R3. I wonder if anybody knows how to catch when i'm making a delta initialization and a delta update in my FM, because i have different parameters and routines from each one.
Thanks in advanced.
Points for helpfull answers.

Hi,
Keep one dummy date field in the structure. Make this dummy date field as delta enabled field. When you do Init load this date field value will be blank and next time when you do load it will have the last upload (in this case init load) date. You have to write a code before open cursor as below:
      LOOP AT s_s_if-t_select INTO l_s_select.
                              WHERE fieldnm = '(dummy date field name)'.
         l_date = l_s_select-low.
      ENDLOOP.
l_date will have the last upload date. This you can use to select the delta records from the table or for the further processing.
If you want to check the value during Init or delta load, go to RSA3 and debug it(Don't use F - Full load. Use I or D in the update field).
Hope this helps.

The DataSource ZGLOBAL_SPND still has no target system for the delta update

Dear Experts,
I have created a Generic Datasource, while checking records in rsa3 iam getting below error.
Error: The DataSource ZGLOBAL_SPND still has no target system for the delta update.
Source system is already created.
For some of the datasources iam getting this msg.
regards
KV

Hi,
Fisrst did u enabled the Delta for Generic.If yes, the in RSA3 select Update Mode as "D" then provide the BI Trget system and execute.
If you correct Target system and update mode D then it should fetch Delta records only...If not please write to SAP about this issue.
Regards
Ram.

How to use Delta Update in InfoSpoke

How to use Delta Update in InfoSpoke & to include in Process Chain

Initialization / delta updates are what we do every day, and it is usually the update method of choice for most data targets. The delta mechanism ensures the consistency of transactional data. So if some data is wrong in the early stage of data flow, we have to not only correct the data itself but also the related records in subsequent data targets.
Unfortunately, such data can't be avoided in daily extractions. In some situations, the data to ODS is correct but reports errors while loading from ODS to Cubes.
Here is one example:
Some FI documents transferred in R/3 with LSMW's background mode and one of the line items 'Negative posting signal' was inserted with 'x' while the right one should be 'X'.
This line time stays cool in my ODS Z1CCWO01, but encounters errors while loaded into several Cubes when the process chain's running.
