DTP Full/Delta loads

I am loading data from one DSO to another. The change log of the source DSO has been deleted for any request before 20 days.
I want to do a full load from active table and then start the delta loads from change log. But the problem is the load is picking up all the previous deltas from change log again, instead of picking deltas after the full load.
Is there a way to do a "init without data transfer", like the option we had before - where it resets the delats so that only the deltas after the full load are picked.
Thanks. Points will be awarded.

Hello Sachin,
In BI7, there's no longer the notion of delta initialization. Just do a delta from your DSO.
Just load the full data in our DSO and launch the delta, then run the deltas for populating your DSO and the corresponding deltas from it.
Hope it helps,

Init ,full,delta load

Hi friends,
can u tell difference between init ,full,delta updates
and what situation we use these updates ?and any more update methods are there other than these?

manohar ,
init - it is used to initialize the data load and will be followed by delta loads thereafter
delta - incremental data loads and can be done only after an init
full - you load all the data at once and do not wish to init. You cannot run a delta load after a full load. you will always have to init first and then do the delta loads.
please refer back to previous postings for more information on the same.

Table with Full / Delta Load information?

Is there a table I can go to where I can see if a cube is a full load vs delta?
Thanks, I will assign points!
~Nathaniel

Hi,
ckeck the table ROOSPRMSC in R/3.It gives you the complete details of your Init and Delta Loads.
hope this helps.
Assign points if useful.

Handling Init/Full/Delta-Loading for a generic DS based on function-module

Hi Experts,
we need to build a generic datasource based on a function-module; and we would like to
implement a slightly different logic in the function-module depending on the data-staging-mode that was selected in the InfoPackage.
What we're missing is a possibility to distinguish (in the ds-function-module) if an init/delta/full-load was requested.
Could you please provide some information/hints about that topic?
Thanks in advance,
Marco

Hi Anjum,
we found an alternative that seems to be closer to SAPs idea of how it should work:
We check the status of the Init-Table (RSA7) - depending on the result
a) Init exists ---> Delta or Full
b) Init does not exist --> Init or Full
we check if the system itself passes a timestamp together with the data-request.
1) If it does so --> Delta/Init
2) If it doesn't provide a timestamp --> Full.
Summary:
a1 --> Delta
a2 --> Full
b1 --> Init
b2 --> Full

What is the diffrence between full load and delta load in DTP

hI ,
I am trying to load the data into CUBE from another cube using DTP ..
There are 2 DTPS ..
1: DTP with full load
2: DTP with DELTA load ..
what is the diffrence betwen thse two in DTP ...
Please can somebody help me

1: DTP with full load - will update all the requests in PSA/source to the target,
2: DTP with DELTA load - will update only new requests to the datatarget
The system doesnt distinguish new records on the basis of changed records, rather by the request. Thats the reason you have datamart status to indicate if the request has been loaded to further datatargets.

Delta loads - for DB Connect and master data.

Hi there,
Would appreciate if any one clarify me on:
1) Are delta loads are possible as far as Master data is concerned?
2) What are all types of data loads (Initial/ delta/ Full)are possible as far extracting data from DB connect is concerned?
Thanks in anticipation.
Rgds,
A.

Hi Ash,
As far as I know, with DB connect you have the only option to have delta functionality - to use ODSs. Make full load from the source system to ODSs. Then update data targets from ODSs. During this update you'll have an option for init/full/delta load.
Best regards,
Eugene

Delta Init DTP DSO- Cube loads all requests

Hi,
i've loaded several Full Request to a DSO (Datasource 2LIS_02_ITM).
I had to to fragment it to 3 months per Full load because otherwise the data volume was too much for the rollback segment.
Now i want to load these requests from the DSO to a Cube.
I created a Delta DTP and selected the "All new data by request" option.
The DTP starts as a Delta Init but selects all open requests at once and crashes with a "ORA-01555: snapshot too old..." error.
As a workaround i created several Full DTPs that only load part of the data but i really want to understand why the Delta Init doesn't work as expected and documented (to load request by request in a new process).
thanks
Carsten

That's the option i've selected.
When monitoring the DTP-Request i see in the head data that all requests from the DSO are selected at once.

Change Delta load to Full in DSO

Is it possible to change Delta load to Full in DSO without recreate it?
Thanks!

Our data comes from other system not R/3. We chose Delta when designed this DSO. But I thought Full load will make validation easier.
I am testing two Update Options in DTP of this DSO. The options are:
1. Further Processing Without Master Data
2. No Further Processing Without Master Data
I had one testing data contain a ITEM NO that doesn't exist in the Master data. I expect to see 0 gets loaded when number 2 option selected. (This worked)
Also I expect to see 1 records get updated to the DSO when Option 1 is chosen. (I still load 0).
Our business people wants to know what are those ITEMs that do not exist in the Master data. Any ideas? Thank you.

Delta load is done,now need to have full load

Hi,
Delta load is done,now need to have full load.
Here for DTP we dont have full repair,what is the process.

Hi,
You will have to use repair full load at infopackage level.
But repair full load should be done only if their is any problem
in the load.
Process
1)selectively delete the data where problem had occured
2)Repiar full load in the infopackage for that selection.
You cant do a direct full load on the same selection as that of delta.
Please assign points if it helped you

Coverting Full load to delta load

Hello All....
I have an infosource which was delta enabled, but by mistake somebody has done it Full Load.Now i dont want to teminate the job.
Can nybody tell me what will be the effect of doing full load & what should i do to convert it to DELTA load again?
Plz help...

Hi,
With a data transfer process, you can transfer data either in FULL extraction mode or in DELTA mode. In FULL mode, the entire dataset of the source is transferred to the target; in DELTA mode, only the data that was posted to the SOURCE since the LAST data transfer is transferred.
So I believe you should be fine as it would only transfer the data from change log which was LAST posted in to your changelog table of datastore.
However;this is my theory and understanding derived from SAP help,might worth taking a shot if you are in DEV or wait for some one from SAP to confirm on the same.
NOTE - Applies only if you want to MIX FULL and DELTA loads of DTP in ODS Datastore ,then activation of REQUESTS could create problem so follow below solution.
Note 967100 - P10:Activate DTP requests from full and delta DTP in DSO

Loading through Process Chains 2 Delta Loads and 1 Full Load (ODS to Cube).

Dear All,
I am loading through Process chains with 2 Delta Loads and 1 Full load from ODS to Cube in 3.5. Am in the development process.
My loading process is:
Start - 2 Delta Loads - 1 Full Load - ODS Activation - Delete Index - Further Update - Delete overlapping requests from infocube - Creating Index.
My question is:
When am loading for the first am getting some data and for the next load i should get as Zero as there is no data for the next load but am getting same no of records for the next load. May be it is taking data from full upload, i guess. Please, guide me.
Krishna.

Hi,
The reason you are getting the same no. of records is as you said (Full load), after running the delta you got all the changed records but after those two delta's again you have a full load step which will pick whole of the data all over again.
The reason you are getting same no. of records is:
1> You are running the chain for the first time.
2> You ran this delta ip's for the first time, as such while initializing these deltas you might have choosen "Initialization without data transfer", as such now when you ran these deltas for the first time they picked whole of the data.Running a full load after that will also pick the same no. of records too.
If the two delats you are talking are one after another then is say u got the data because of some changes, since you are loading for a single ods to a cube both your delta and full will pick same "For the first time " during data marting, for they have the same data source(ODS).
Hope fully this will serve your purpose and will be expedite.
Thax & Regards

Converting Full Load - Delta load

Hi Experts,
I am trying to convert ODS from Full Load to Delta Load.
The problem is already there are full req so its not allowing me to activate delta.
I have tried running the program "RSSM_SET_REPAIR_FULL_FLAG" which would convert full req into repair req and then I should be able to load Init/Delta.( see OSS Note 689964)
Problem is even after running the program succesfully I m getting same message and not able to activate Init.
I again tried running running the prog but now progr does nt show any req which could be converted to Repair req.
So how to proceed from here and Full load ODS -> Delta...???
All help would be appreciated and awarded by points...
Thanks in advance!!!
Sorabh

Hi Ajai,
I checked RSREQDONE; in tht Qm status of req is Green...I dont know what I shud check in this table..
Also as per my understandings loading thru reqs in PSA is another way (if the request still exist in PSA)apart from the program given.
Program shud work in any condition whether req is there in PSA or not.
Correct me if I am wrong..
but again struck ..on same issue...:)..
Thanks,
Sorabh

Full vs. Delta Load

Hi BI-Experts!
This is a rather general question.
Is there a recommendation when to use Full or Delta Load?
I know the functional differences but do SAP or some technical reasons say that each of them may only be used in special cases?
For example Delta Load can only be used with SAP source systems?
Best regards,
Philipp

Hi Philipp,
This is a pretty open-ended question. I will give you a few examples of when I use each ....
Delta's:
1.) If the record set is large and changes a lot daily. If you have a large initial load, let's say 2Million records and you get about 200k records per month, then you want to use a delta mechanism. There are just too many records to reload daily.
2.) If the record set is wide (many fields instead of a few), it will take less load time to run a delta than a full load.
3.) Datasource restrictions....some business content datasources don't have full loads and vice versa (some don't have deltas).
4.) Do my loads take too long? If so, I will convert full loads to delta's to shave off time here and there.
Full
1.) I gauge this mainly based on load time. If it takes 5 minutes to load 100k records, then it's going to take longer to figure out what delta's were missed (if there was a problem) than it would to just reload the dataset.
2.) Do my requirements dictate that I need to drop and reload the dataset? The best example of this would be the current year's forecast. Some companies revise the forecast and don't want to keep any previous revisions.
3.) Some data loads load a snapshot of a specific date. So, if I wanted to take a snapshot of inventory in a DSO/ODS on Monday, I would Datamart it into a Cube doing a full load for Monday's date.
Hope it helps!
Thanks,
Brian

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.

DELTA Load gives wrogn values Where as FULL load gives right for FI Report.

Pls help!
I am trying to calculate Opening Balance for FI AR postings for which i have coded in end routine in Transformations.
The new fields OPENING BALANCE CREDIT/DEBIT get values from my routine.
However the problem I am facing is,
I only Get Correct VALUES for the OPENING BALANCE only when I DO FULL LOAD.
If i do delta load ,i get wrong values.
Thank you for reading.

Hi,
When you make delta load, you are just getting unexisting FI data. But I think that you need all the data in the cube to calculate the opening balance for the day.
Therefore, I don't think that delta load is a good way if you calculate Opening balances.
If you want to use delta load , fill the cube and then create another cube being filled from that cube(which is loaded with delta) and implement your routine between this two cubes.
Hope this helps.
Thanks
