Init load and full load

hi friends
can u plz give me diff between init load and full load

Hi Raj,
You can read about the details here:
http://help.sap.com/saphelp_nw04/helpdata/en/80/1a65dce07211d2acb80000e829fbfe/content.htm
Full load brings all the data (as per selection if any) from the source related to this particular extractor. The init load will also do the same, but will set a delta pointer so that for the next load only the changed or new records need to be extracted.
Hope this helps...

Perform INIT, DELTA, and FULL Load from R3 to BI 7.0

Hi,
Could anyone please give me the information about how to perform the following to load data from the R3 system to the BI 7.0 system:
1. INIT Load
2. Delta Load
3. Full Load
4. RealTime Data Acquisition
Where can I find the settings for all the above in DTP?
For Real Time Data Acquisition; Don't I have to load the data from the data soruce to the PSA........
Does the data goes directly from the data source to the data target throguh Daemon Process? I read the SAP Help doc's but still little confused.......could any one please explain it in your clear way.
Thank, I will assign the points.

the first three are similar to 3.5

Inits, deltas and full

Hi Experts
I am trying to clarify the data flow in 2004s.
1. If I am loading from R/3 datasource (Which is delta enabled) to a DSO in BW, i first load a full load with initialization with data transfer using an infopackage. I do the delta load with another infopackage selecting delta.
2. The above step only brings data to the PSA. From the PSA, DO I NEED TWO DTPS? one for full and other for delta?
3. From the DSO to the cube, do I need two DTPs again? Or a single DTP with extraction from the change log as delta is enough, even for the first load from the DSO to the cube?
Can someone confirm / clarify this?
Jason

1. If I am loading from R/3 datasource (Which is delta enabled) to a DSO in BW, i first load a full load with initialization with data transfer using an infopackage. I do the delta load with another infopackage selecting delta.
Thats correct.
2. The above step only brings data to the PSA. From the PSA, DO I NEED TWO DTPS? one for full and other for delta?
you need not do two DTP's to collect the data from PSA, design one DTP in delta mode from PSA, it would all the request in the PSA, no matter if its full or delta in the first run, from the second run it would pick all the requests that are new after the first run.
3. From the DSO to the cube, do I need two DTPs again? Or a single DTP with extraction from the change log as delta is enough, even for the first load from the DSO to the cube?
just as said in point 2, one DTP with change log as delta would do the job

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

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.

Whats the Actual use of the Setup table apart from the Full/Init loads

Hi guru's
could u explain whats the Actual use of the Setup table apart from the Full/Init loads in Lo Extraction

Hello Guru,
The Setup table is used mainly for storing the Historical data whereas the new and changed records will be maintained in the Update table.
By storing the Historical data in the setup table you don't need to disturb the Application table anymore.

Difference: Full load, Delta Load & INIT load in BW

Hi Experts,
I am new to SAP BW Data warehousing.
What is the difference between Full load, Delta Load & INIT load in BW.
Regards
Praveen

Hi Pravin,
Hope the below helps you...
Full update:
A full update requests all the data that corresponds with the selection criteria you have determined in the scheduler.
You can indicate that a request with full update mode is a full repair request using the scheduler menu. This request can be posted to every data target, even if the data target already contains data from an initialization run or delta for this DataSource/source system combination, and has overlapping selection conditions.
If you use the full repair request to reload the data into the DataStore object after you have selectively deleted data from the DataStore object, note that this can lead to inconsistencies in the data target. If the selections for the repair request do not correspond with the selections you made when selectively deleting data from the DataStore object, posting this request can lead to duplicated data records in the data target.
Initialization of the delta process
Initializing the delta process is a precondition for requesting the delta.
More than one initialization selection is possible for different, non-overlapping selection conditions to initialize the delta process when scheduling InfoPackages for data from an SAP system. This gives you the option of loading the data
relevant for the delta process to the Business Information Warehouse in steps.
For example, you could load the data for cost center 1000 to BI in one step and the data for cost center 2000 in another.
The delta requested after several initializations contains the upper amount of all the successful init selections as the selection criterion. After this, the selection condition for the delta can no longer be changed. In the example, data for cost
centers 1000 and 2000 were loaded to BI during a delta.
Delta update
A delta update requests only the data that has appeared since the last delta. Before you can request a delta update you first have to initialize the delta process. A delta update is only possible for loading from SAP source systems. If a delta update fails (status red in the monitor), or the overall status of the delta request was set to red manually, the next data request is carried out in repeat mode. With a repeat request, the data that was loaded incorrectly or incompletely in the failed delta request is extracted along with the data that has accrued from this point on. A repeat can only be requested in the dialog screen. If the data from the failed delta request has already been updated to data targets, delete the data from the data targets in question. If you do not delete the data from the data targets, this could lead to duplicated data records after the repeat request.
Repeat delta update
If the loading process fails, the delta for the DataSource is requested again.
Early delta initialization : This is a advanced concept, but just for your information ...
With early delta initialization you can already write the data to the delta queue or to the delta tables in the application while the initialization is requested in the source system. This enables you to initialize the delta process, in other
words, the init request, without having to stop posting the data in the source system. You can only carry out early delta initialization if this is supported by the extractor for the DataSource that is called in the source system with this data
request. Extractors that support early delta initialization were first supplied with.

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...

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.

Debjani.....

Init & Delta After Full Load

hii Experts
I have one doubt please clarify that.
If i have a Cube and i m pulling data on basis of Full Load . Then i switch to delta load, before that i took the INIT load without data transfer.
But after a couple of days i need to pull the full load again for that particular period, for that i delete the INIT request & also the Delta request from Cube & PSA. & after full load i want to pull the delta load.
Now my doubt is how does this process impact on loading process?Is the previous init & delta also have some impact on the current delta loading???
Thanks in Advance
Neha

Hi,
There is absolutely no problem in doing a full loaf after init delta.
doing full load doesnt disturb the delta status.
Here i explain how an init and delta works
Init and Delta :
Once you are done with fetching all data from source using fullload, you have to run init.
all the new records that appear in the source system after init will sit in the delta queue.
when ever you run delta after the init, all the new records will coime to Bi and once this delta runs succesfully, these records will be cleared from the queue in source system and the new records from then comes to the queue.
this way, we can be sure that there is no loss of data.
Full load after delta :
now comming to your answer, if you run a full load, the data is not fetched from the delta queue and it doesnt disturb the queue in any way. it only brings all the data from soure(according to selection condition). so the delta is not disturbed in any way.
Repair Full Request :
The repair full request acts in the same way as full load in fetching data from source.
the only difference is in updating the target.
Rather than updating the data in the request, it checks out for the changes in already loaded data and update if there are any changes (Repairing the data already loaded.
That means there is no impact of previous init without data transfer in the current delta loading?
If you go thru the above explanation you can get this answer easily.
Init is used to set the delta pointer due to which the present delta is working fine.
Hope this answer helps you,
Thanks and Regards,
Srinath.

Init Load and RSA3

I have carried out a transport to Q/A and part of the transport included an Init InfoPackage which was created on Development. I have used this package to schedule an immediate Init load. It is not extracted anything so far but should have, could this be because the package was created on Development? If so how do I resolve.
As a test I went to RSA3 to see if I could carry out a test extract, nothing is being extracted in the sense that the process is still running, could this be because I am extracting on B/W or is there no relationship in that sense? Thanks

Hi,
First of all, count the entries in setup table MC11VA0ITMSETUP, if it has zero records then fill the set up table using tcode OLI7BW.Execute the job in back ground here. And also select the termination date in future.
Do not start the execution of Info package till the job is completed for filling the set up table.

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.

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

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...
