DAC Load strategy - Increamental Load and Full Load.

Hi all,
Thanks for taking the time to review my post.
Environment
Oracle BI Applications Financial & Project Analytics 7.9.6
OBIEE 10.1.3.4.1
DAC 10.1.3.4.1
Informatica 8.6.0 Hot Fix 4.0
Data Source: Oracle Enterprise Business Suite 11.5.10
Problem
We are working on implementing Supply Chain and Order Management analytics and Financial Analytics in OBIEE Applications 11.5.10.
Another team has already configured Financial – General Ledger and Financial Revenue from Financial Analytics module and we cannot use their Container.
Now we need to configure new Container for remaining modules from Financial Analytics and Chain and Order Management analytics.
As per our Implementation plan we would build and execute the execution plan with those subject areas other than General Ledger and Revenue from Financial Analytics. As we know Out Of Box provides tasks for individual Subject areas and there are common tasks which would load common dimension tables [tables for GL and Revenue area already populated with refresh dates] used across the subject areas.
So when we run our execution plan for remaining subject areas in Financial Analytics/ Supply Chain and Order Management analytics do we need to disable those common task which would load common dimension tables so that other teams work don’t get impacted[common dimension tables will not get impacted] or let allow DAC to decide what to run (Full Load or Incremental Load for those common tasks) based on Refresh dates in those dimension tables.
Thanks!

DAC Commands for Incremental and Full load

Hi,
I'm implementing BIApps 7.9.6.1 for a customer. For R12 container, I noticed for 5 DAC tasks the command for Incremental and Full load starts with "@DAC_" and ends with "_CMD". Due to this, the ETL load fails. Is this a bug..?
Thanks,
Seetharam

You may want to look at Metalink note ID 973191.1:
Cause
The 'Load Into Source Dimension', has the following definition:
-- DAC Client > Design > Tasks > Load Into Source Dimension > Command for Incremental Load = '@DAC_SOURCE_DIMENSION_INCREMENTAL'
and
-- - DAC Client > Design > Tasks > Load Into Source Dimension > Command for Full Load = '@DAC_SOURCE_DIMENSION_FULL'
instead of the actual Informatica workflow names.
The DAC Parameter is not substituted with appropriate values in Informatica during ETL
This is caused by the fact that COMMANDS FOR FULL and INCREMENTAL fields in a DAC Task do not allow for database specific texts as described in the following bug:
Bug 8760212 : COMMANDS FOR FULL AND INCREMENTAL SHOULD ALLOW DB SPECIFIC TEXTS
Solution
This issue was resolved after applying Patch 8760212
The documentation states to apply Patch 8760212 to DAC 10.1.3.4.1 according to the Systems Requirements and Supported Platforms Guide for Oracle Business Intelligence Data Warehouse Administration Console 10.1.3.4.1.
However, Patch 8760212 has been made obsolete, recently, in this platform and language. Please see the reason stated below on the 'Patches and Update' tab on My Oracle Support.
Reason for Obsolescence
Use cumulative Patch 10052370 instead.
Note: The most recent replacement for this patch is 10052370. If you are downloading Patch 8760212 because it is a prerequisite for another patch or patchset, you should verify whether or not if Patch 10052370 is suitable as a substitute prerequisite before downloading it.

Diff b/n Repair full and Full load

Experts
Please explain diff b/n Repair full request and Full load.
If I do Repair full request instead of Full load ,is there any problem in the data ?
Many thanks
Manoj

Hi Manoj,
You can use a request that was selected as a repair request via Scheduler ® Repair Full Request to carry out a full update in any data target. This also applies to data requests that already contain data from an initialization run or deltas for this DataSource/source system combination, and that have overlapping selection criteria.
The difference between a Full Load and a Full Repair load is only evident in the case of loading to an ODS (to which you are also loading Init and Delta from the same datasource). If you ODS has the Init request active and you load a Full request, the data will not be activated. You should always use a Full Repair request when you want to load a full load to the ODS. For a cube it does not make a difference as the sequence of data loads is in important in a cube.
If you have accidentally not marked the request as a repair request, you can convert is using SE38 > RSSM_SET_REPAIR_FULL_FLAG
Hope this helps...

Diffrance between full repair and Full load .

hello ,
could you please let me know , what is the diffrance between full repair and Full load .
Regards

Hi,
Full Repair :
If you indicate a request in full update mode as a repair request, then it is able to update that request in data targets even if they already contain data from initial runs or deltas for this DataSource / source system combination and with overlapping selections.
Consequently, a repair request can be updated to ODS without checking the sequence of delta requests. The system supports loading in an ODS object by using the repair request without having to check the data for overlapping or request sequencing.
Full load :
Pulls the entire data from the source system to the BI system
Assign points if it helps
Thanks & Regards

Init load, delta load and full load

Hi BW,
Please when can I use init delta, delta and full load in a data load process.
Which of them is suppose to be in a process chain and which one is manual.
Regards.

Hi,
When you want to run delta, you have to initialize it first, thats when you run the init delta.Here you have 2 options with data transfer and without data transfer. If the data target is empty and there's no data, you can run the init with data transfer. This'll act as a full pull and also set up the initialization. If there's data already present, then you are better off running the init w/o data transfer. This dosen't pull over any data, but just sets up the initialization.
Then you can start using the delta pulls.That'll just bring over the changes and any new records rather than the whole data and is much more efficient.
You can use full pulls for say generic datasources that are not delta enabled or during a first time data load, or if there is a specific business requirement that needs you to pull over the full data everyday. Or in cases where the std datasource is not delta enabled.
Cheers,
Kedar

Delete and full load into ODS versus Full load into ODS

Can someone please advise, that in the context of DSO being populated with overwrite function, would the FULL LOAD in following two options (1 and 2) take the same amount of time to execute or one would take lesser than the other. Please also explain the rationale behind your answer
1. Delete of data target contents of ODS A, Followed by FULL LOAD into ODS A, followed by activation of ODS
2. Plain FULL LOAD into ODS A (i.e. without the preceeding delete data target contents step), Followed by activation of ODS
Repeating the question - whether FULL LOAD in 1 will take the same time as FULL LOAD in 2, if one takes lesser than the other then why so.
Context : Normal 3.5 ODS with seperate change log, new and active record tables.

Hi,
I think the main difference is that you with the process "Delete and full load" you will only get the full loaded data inside the dso. With full load you the system uses the modify logic (overwrite for all datasets already in the dso) and insert for all new datasets which are not inside yet inside the dso

Delta Load and Full load

What is the difference between delta load and full load?when are they used?

Hi,
Delta loads - Brings only the changed or newly added data to the data target...
Full loads - Brings all the data whether it is old, new or changed data to the data target...
Full loads are usually used to load master data since it wont change in course of time and delta loads are used when there are large amount of data to be extracted from the source system. It entirely depends on the requirement...

Full Load" and "Full load with Repair full request"

Hello Experts,
Can any body share with me what is the difference between a "Full Load" and "Full load with Repair full request"?
Regards.

Hi......
What is function of full repair?? what it does?
How to delete init from scheduler?? I dont see any option like that in infopackage
For both of you question there is a oss note 739863-Repairing data in BW ..........Read the following.....
Symptom
Some data is incorrect or missing in the PSA table or in the ODS object (Enterprise Data Warehouse layer).
Other terms
Restore data, repair data
Reason and Prerequisites
There may be a number of reasons for this problem: Errors in the relevant application, errors in the user exit, errors in the DeltaQueue, handling errors in the customers posting procedure (for example, a change in the extract structure during production operation if the DeltaQueue was not yet empty; postings before the Delta Init was completed, and so on), extractor errors, unplanned system terminations in BW and in R/3, and so on.
Solution
Read this note in full BEFORE you start actions that may repair your data in BW. Contact SAP Support for help with troubleshooting before you start to repair data.
BW offers you the option of a full upload in the form of a repair request (as of BW 3.0B). If you want to use this function, we recommend that you use the ODS object layer.
Note that you should only use this procedure if you have a small number of incorrect or missing records. Otherwise, we always recommend a reinitialization (possibly after a previous selective deletion, followed by a restriction of the Delta-Init selection to exclude areas that were not changed in the meantime).
1. Repair request: Definition
If you flag a request as a repair request with full update as the update mode, it can be updated to all data targets, even if these already contain data from delta initialization runs for this DataSource/source system combination. This means that a repair request can be updated into all ODS objects at any time without a check being performed. The system supports loading by repair request into an ODS object without a check being performed for overlapping data or for the sequence of the requests. This action may therefore result in duplicate data and must thus be prepared very carefully.
The repair request (of the "Full Upload" type) can be loaded into the same ODS object in which the 'normal' delta requests run. You will find this request under the "Repair Request" option in the InfoPackage (Maintenance) menu.
2. Prerequisites for using the "Repair Request" function
2.1. Troubleshooting
Before you start the repair action, you should carry out a thorough analysis of the possible cause of the error to make sure that the error cannot recur when you execute the repair action. For example, if a key figure has already been updated incorrectly in the OLTP system, it will not change after a reload into BW. Use transaction RSA3 (Extractor Checker) in the source system for help with troubleshooting. Another possible source of the problem may be your user exit. To ensure that the user exit is correct, first load a user exit with a Probe-Full request into the PSA table and check whether the data is correct. If it is not correct: Search for the error in the exit user. If you do not find it, we recommend that you deactivate the user exit for testing purposes and request a new Full Upload. It If the data arrives correctly, it is highly probable that the error is indeed in the user exit.
We always recommend that you load the data into the PSA table in the first step and check the result there.
2.2. Analyze the effects on the downstream targets
Before you start the Repair request into the ODS object, make sure that the incorrect data records are selectively deleted from the ODS object. However, before you decide on selective deletion, you should read the Info Help for the "Selective Deletion" function, which you can access by pressing the extra button on the relevant dialog box. The activation queue and the ChangeLog remain unchanged during the selective deletion of the data from the ODS object, which means that the incorrect data is still in the change log afterwards. After the selective deletion, you therefore must not reconstruct the ODS object if it is reconstructed from the ChangeLog. (Reconstruction is usually from the PSA table but, if the data source is the ODS object itself, the ODS object is reconstructed from its ChangeLog). You MUST read the recommendations and warnings about this (press the "Info" button).
You MUST also take into account the fact that the delta for the downstream data targets is created from the changelog. If you perform selective deletion and then reload data into the deleted area, this may result in data inconsistencies in the downstream data targets.
If you only use MOVE and do not use ADD for updates in the ODS object, selective deletion may not be required in some cases (for example, if incorrect records only have to be changed, rather than deleted). In this case, the DataMart delta also remains intact.
2.3. Analysis of the selections
You must be very precise when you perform selective deletion: Some applications do not provide the option of selecting individual documents for the load process. Therefore, you must first ensure that you can load the same range of documents into BW as you would delete from the ODS object. This note provides some application-specific recommendations to help you "repair" the incorrect data records.
If you updated the data from the ODS object into the InfoCube, you can also delete it there using the "Selective deletion" function. However, if it is compressed at document level there and deletion is no longer possible, you must delete the InfoCube content and fill the data in the ODS object again after repair.
You can only perform this action after a thorough analysis of all effects of selective data deletion. We naturally recommend that you test this first in the test system.
The procedure generally applies for all SAP applications/extractors. The application determines the selections. For example, if you cannot use the document number for selection but you can select documents for an entire period, then you are forced to delete and then update documents for the entire period in the data target. Therefore, it is important to look first at the selections in the InfoPackage exactly before you delete data from the data target.
Some applications have additional special features:
Logistics cockpit: As preparation for the repair request, delete the SetUp table (if you have not already done so) and fill it selectively with concrete document numbers (or other possible groups of documents determined by the selection). Execute the Repair request.
Caution: You can currently use the transactions that fill SetUp tables with reconstruction data to select individual documents or entire ranges of documents (at present, it is not possible to select several individual documents if they are not numbered in sequence).
FI: The Repair request for the Full Upload is not required here. The following efficient alternatives are provided: In the FI area, you can select documents that must be reloaded into BW again, make a small change to them (for example, insert a period into the assignment text) and save them -> as a result, the document is placed in the delta queue again and the previously loaded document under the same number in the BW ODS object is overwritten. FI also has an option for sending the documents selectively from the OLTP system to the BW system using correction programs (see note 616331).
3. Repair request execution
How do you proceed if you want to load a repair request into the data target? Go to the maintenance screen of the InfoPackage (Scheduler), set the type of data upload to "Full", and select the "Scheduler" option in the menu -> Full Request Repair -> Flag request as repair request -> Confirm. Update the data into the PSA and then check that it is correct. If the data is correct, continue to update into the data targets.
And also search in forum, will get discussions on this
Full repair loads
Regarding Repair Full Request
Instead of doing of all these all steps.. cant I reload that failed request again??
If some goes wrong with delta loads...it is always better to do re-init...I mean dlete init flag...full repair..all those steps....If it is an infocube you can go for full update also instead of full repair...
Full Upload:
In full upload all the data records are fetched....It is similar to full repair..Incase of infocube to recover missed delta records..we can run full upload.....but in case of ODS does'nt support full upload and delta upload parallely...so inthis case you have to go for full repair...otherwise delta mechanism will get corrupted...
Suppose your ODS activation is failing since there is a Full upload request in the target.......then you can convert full upload to full repair using the program : RSSM_SET_REPAIR _ FULL_FLAG
Hope this helps.......
Thanks==points as per SDN.

Source for Init with data transfer and full load

Hi Experts,
1. Please tell me where the data comes when we do the
    following actions :-
    a) Init with data transfer
    b) Full load
i want to know the source of data i.e (setup table or main table or any other table)
Helpful if you can provide the data-flow.
kindly tell which is prefrable and why?
Regards,
RG

Hi.......
When you do init with data transfer it will read data from the set up table only..........but beside this it will also set the init flag..........due to this from next time any new records will go to the delta queue...........and next time when you run delta load it will pick records from delta queue...........
Now suppose data are alrady available in the BW side...........then you can run init without data transfer.......this will only set the init flag.........it will not pick any records.........
Extraction structure gets data from set up table in case of full upload ............and in case of delta load from delta queue.......
Regards,
Debjani...........

Question on Deltas after Init and Full load

Hi
We have an ODS X pushing data to two cubes A & B. ODS X data is initialized to Cube A long back and deltas are loading every day. Now We have recently created Cube B and made a fulll load from ODS X and loading the Deltas from ODS X with same info package we are using to load the deltas in to cube A. Do we get any data inconsistencies if we load like this ? Do I need to make a new init for Cube B to get proper deltas ? I'm hoping that Deltas will automatically take care of reversal in Cube B too...Please advice.
Thanks
Sam

This looks fine, since u have already done full load from X to B, and currently loading delta to both A n B , it is fine, no need for new init.

Rathy

Difference between delta load and full load

HI,
i am getting confused with full load and delta load.
The scenario is as follows:
I have 4 records which i need to pass to DSO.(Standard DSO)
These are the fields and records.
IO_amount          io_QTY         0UNIT     0CURRENCY     Matnr
1519     195     EA     USD     MM01
2643.85     12     EA     USD     MM02
3580.4     10     EA     USD     MM03
6049.8     12     EA     USD     MM04
Now i need to change the record as
IO_amount          io_QTY         0UNIT     0CURRENCY     Matnr
1500     195     EA     USD     MM01
2643.85     12     EA     USD     MM02
3580.4     10     EA     USD     MM03
6049.8     22     EA     INR     MM04
When i passed it as full and delta load but could not make out any difference..
I can see the data only in active data and change log tables.how can i see that in DSO?
please help out,Points for sure.

Hello Susmitha,
You are right & your view of data is also correct
But only thing here is ODS which you are using mait have Overwright option in its Update Rules /Transformations
Here Q is
Which fields are in KeyFields in DSO Design
If
this Field Values are same in Delta are Full Upload
it will overwrite the records in ODS / DSO
If not
it will add the records to DSO /ODS
Comming to Delta & Full Loads
If you use Full always all data Present will be loaded
if you use Delta always changed & New records will be updated
This happens through Pointers Set ( Snap Shot of Previous Load )
Some tables where you can see RSOLTPSOURCE,RODELTAM etc
Try to wiew this ,Its tough to get
Thanks

COPA delta and Full load inconsistent result

Hi ,
whn i do a Full load for COPA(datasource 1_CO_PA1159000) for one particular order number, it returned 5 line items.but when i tried to do Initialization load it returned only 4line items. One line item is missing.
Can anyone let me know what could cause this inconsistence between a full load and initialization load on the same datasource extraction.
Appreciate feedback from anyone.
Thanks.
Regards,
Maili

Hi,
Data could be picked from summarization levels or the base tables. The source of data may vary for Full/Init. Please check section 3.4 Data source for CO-PA extraction in the How to CO-PA extraction doc....

Init and full load

Giving a selction criteria during Init load .
I have two ODS's - ZODS1 and ZODS2 . I need to feed ODS2 from ODS1 .
When i try to do an init load , I do not get an option to make
any selections although when i maintained the export data source for
ODS1 i checked the fields required for selection . I am able to
do a selection if i do a FULL load instead of an INIT .
Can some one pls clarify ? I wish to do an Init followed by delta
for certain recordtypes ( say recordtype=z)

hi oops,
u have to understand the business process.
try to do processes in a simple way. as u say u need need to load a second ODS with filtered data from first ODS by INIT(FOR further delta) by selection.
u can directly load DSO2 from psa with Selection condition.
when u load data from an infoprovider generate datasource following that u give update data target, which is generated by the system this will not have any selection condition by default .
so u can load all the delta but not by filtering records.
or u have to filter records by routines.
reward points if helpful.

Delta AND Full load on 2LIS_11 Extractor

Dear All,
I have a 2LIS_11** extractor in place which loads data via delta. Now I want to add a full load through the same extractor to a new infoprovider.
What is the scenario to do this? I know that I need to fill the setup tables, but won't that conflict with my delta load?
Your response will be appreciated and rewarded.

Hi,
as long as you don't load the data into your already existing ODS you will be fine.

Siggi

Delta and Full Load question for cube and ODS

Hi all,
I need to push full load from Delta ODS.
I have process chain.... in which the steps are like below,
1. R/3 extractor for ODS1 (delta)
2. ODS1 to ODS2 (delta)
3. ODS2 to Cube ---> needs to be full load
Now when i run process chain by further processing automatically ODS2 does init/delta for Cube.
How can i make it possible for full load ??
can any one guide anything in this ?
Thanks,
KS

Hi,
1. R/3 extractor for ODS1 (delta) : This is OK, normally you can put the Delta InfoPack in Process Chian
2. ODS1 to ODS2 (delta): It automatically flow from ODS1 to ODS2 (you need to select Update Data automaticall in the Targets at the time of ODS creation)
3. ODS2 to Cube ---> needs to be full load :
This you create a Update rules from ODS1 to Cube then Create InfoPackage in between ODS2 and Cube then do full loads. You can delete the data in the CUbe before the load ann dthen do Full load to Cube.
Note: In ODS2 don't select Upadate Data autmaticlly to Data Targets
Thanks
