How to do delta load after full load

Hi,
I did full loads for my Data target.
I have 15 requests on my Data target.
Now i want to do delta load.
Please help me how to do delta load even after full loads.
Advance thanks.
Regards,
Rafi

Hi,
change in my post!!!
after full load you can go for delta,but it is not viceversa
if you want to run delta
since you have done prior full loads,,do init without data transfer which will sets the init flag
now run delta
please also check is your datasource supports delta or not
try RSA6, datasource and display,
check if 'delta update' is marked
or table ROOSOURCE field DELTA
Cheers,

How to change Delta Datasource to Full Load?

Hi All,
I have an issue in my report which has Inbound Datasource (customized) from EKES and GRn from VBFA customized datasource.
Currently,
EKES is FULL UPDATE*
VBFA is DELTA UPDATE
My Scenario steps:
Step1:Inbound Created --EKES
Step2:GRn done--VBFA
Step3:Grn Reversed--VBFA
Step4:Inbound Deleted.--- EKES
So When the user deleted the INBOUND after REVERSAL, my EKES is full update, so it doesn't capture the deleted INBOUND based on our Datasource design to FILTER the AVAILABLE INBOUND. by type selection.
so before deletion GRN done in STEP 2, which is alreadt pushed to BI and after deletion of Inboubd GRN from VBFA is DELTA UPDATE, it doesn't capture the Deletion data...
In order to remove the deleted INBOUND from VBFA Infoprovider, I am planning easiest way to do FULL UPDATE...
May what are the precaution and steps to convert the DELTA update to Full UPDATE?
My flow 2PSA(EKES & VBFA)>2DSO(frm EKES & VBFA)->CUBE--->MultiProvider
Pls provide a good suggestion.

Hi ,
I mean to say, losing data in the sense..Once I do Full LOAD, will there any chance I miss data.
Also correct my below steps, if I am wrong,
1.Delete data from Target and PSA.
3. Run setup table-----HERE MY CONFUSION comes....my datasource is 0FI_GL_14. IT IS A FI datasources and this is not LO Method to do SET UP TABLE... or no need this step
2. Create Info Pak with FULL UPDATE.and run the Info pak
3. then run the DElte infopak, how the delta is set up..?
May I know what are the steps for FULL Update for FI?.
Thanks!

Delta load after full load

Hi gurus
We are doing delta loads to a cube which is initialized in 2007.
Now we have some problem with the data cause 2 deltas are missing for Aug
so I just want to selective deletion for aug and i want to do a full load for aug
my doubt is
after that full load daily delta will be sucessfull?
Thanks in advance
Regards
a

Hi,
Before going on with the load, check the following points:
1. Check if all the delta has been moved up to the cube and all the data request in lower level has datamart status set.
2. If there are some request without data mart status move those reqeust to cube before doing the full load.
Then go for the selective deletion from the cube and reload as full update. You should be able to load delta further. There wont be any problem. Even if you have problem, since you have made sure that all the request has gone up and delta mart has been set in lower level you can break the init and reinit from lower level to current cube.
Hope this is clear.

How to make delta possible on full load datasources

Hi All,
What would be best option to enable delta to existing business content DataSource like in Project systems:
0PS_DAT_MLS -- Dates milestones
Is there any options?
Any help greatly appreciated.
Best Regards,
Reddy.

Hi,
one option would be to figure out the underlying table(s) and either:
1- identify a field like changed date/tiem or timestamp or number in order to create a generic datasource delta enabled on such field.
2- create a message type / change pointer monitoring changes on the relevant fields you want to load; finally create a generic datasource based on a function module reading and resetting your custom change pointer.
hope this helps...

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.

How to execute a method after page Load?

My question is very similar to what was discussed in following thread:
How to execute a method after page Load?
My requirement is that I want to run a method in backing bean of a page, immediately after the page gets loaded. In that method I want to invoke one of the method action included in the pagedef of this page, conditionally.
I tried using the approach given in the above thread, i.e to use <f:view afterPhase="#{backing_security.setPermPriv}">, but the problem is that our page is not using 'f:view' , so I explicitly added one f:view with afterPhase property set , but it is not working, page it self is not getting loaded, it is throwing the error:
Root cause of ServletException.
java.lang.IllegalStateException: <f:view> was not present on this page; tag [email protected]e8encountered without an <f:view> being processed.

Hi,
I assume that your view is a page fragment and here - indeed - the f:view tag cannot be used. If you use ADF then one option would be to use a custom RegionController on the binding layer to listen for the render phase to invoke the method. Another option would be to use a hidden field (output text set to display="false" and have this component value referencing a managed bean property. The managed bean property's getter method can now be used to invoke the method you want to run upon view rendering

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...

Delta load to Full load

Hello Gurus,
As per my knowledge while creating delta load form R/3 to BW we need to declare the type of load in R/3 and in the infopackage ....
Where my doubt come on,
i need to convert delta load to full load for one info object ,is their any steps to do in R/3 for changing the type of load .
where i had just changed the load type in only Info package ...is it runs fine.
Plz assist me
Thanks in advance
SAP

Hi,
There is nothing specific needs to be done in R/3.
A data source is delta enabled but still you can load it through full load and in that case you need not do an initialization just schedule a full load package.
i need to convert delta load to full load for one info object ,is their any steps to do in R/3 for changing the type of load .
For this just delete the init which is present there and create the new package with option full update.Just make sure that the last delta is loaded for precaution.
Since infoobject is overwrite so no need to delete the data also every day there will be full load and it will bring the new data along with.
This wil start loading the full load into your object.
Hope it clears
Thanks

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.....

How to make LIS Extractor nightly full load

Hello All,
We need an LIS Extractor to be a full load. It appears Full Load only reads setup tables. How can we do a full load for a LIS Extractor?
Thanks!

Hi All,
Here is our scenerio:
I am referring to the LO Cockpit.
We have deltas coming over to a DSO that has a key of order number, material and batch. Now, when the order is created, for example, it will have batch NULL because we have not determined what batch to use yet. It could remain like this for days. In the meantime this record comes over to BW...just fine and updates. Now, we have decided for this order that exists in BW with a batch of NULL that we allocate a batch to it now. Now this record comes over to BW and it creates a new record. So we have 2 records in BW, one with batch NULL and one with batch updated. We really only want to see the record with batch updated.
We also thought about, what happens if we assign a batch (after the record came over to BW as batch NULL), then this creates 2 records as mentioned above and then now we change this batch to yet another batch. Now when this record comes over to BW this order will have 3 records by batch, yet only the latest is valid.
So we thought a full load would work, which it would. How do you handle such a scenerio for deltas? We load to DSO as mentioned and then push to a Cube.
Thanks

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
Hari

Give difference between full load, delta load, repair full load

Can i run full update after delta load?? if yes tell me a scenario??Can anyone tell me the difference between all three & when to use these??
Regards,
Asish

Hi,
For Repair full load please check OSS note 689964 which is about repairing the full load by executing the program RSSM_SET_REPAIR_FULL_FLAG.
Basically in this you provide your ODS, Data Source and Source System name and execute the program RSSM_SET_REPAIR_FULL_FLAG and hit Repair full load.
It will repair the full load.
But after this you cannot go directly for delta load which is for new added records or changed records. Before delta load do initialization without data loading and then go for delta load.
So delta load will run after init run (without data transfer) and add new added record or changed records to exisitng full upload records.
Technically you cannot go for delta load with out init load.
So, If you have already done full load, you can go for delta load after doing initializing (init load) without data loading.
Hope it helps.

Mona

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
