Question on Delta Init Loads

Hi All,
I have a basic question on Delta Inits. I am a beginner in BW and would truly appreciate any input.
At my company, we currently are doing delta loads on the cube 0RT_C35 (Material Movements). They did the Delta Inits prior to that.
Now if we were to add new fields to the cube and need to populate data to the new fields from the beggining, how do I go about doing it..?
Should I delete the Delta Init requests and redo the Delta Inits..? What will happen to the Delta loads that are running daily then..?
Can someone please give me the steps that I need to follow in a sequence.
Like I said, it might be a basic question..but I am not familiar with this process.
Appreciate your help.

Thank You very much Ravi.
I will not be doing it today based on the priority of the tasks..but this is something I will have to do eventually in the next 1-2 weeks. I will definitely let you know how it goes.
So once the mapping and everything is in place and is ready to be loaded, bascially I need to delete data from the datatarget, put the delta job on hold, reinit the delta requests and then I should be able to do the delta jobs again right..?
Thank You so much.
The other issue is that there are probably 25 Delta inits that they did based on the number range for the Material Nbr. But they have only 1 delta. So does the delta job cover the data for all the Delta Init requests..?
I am assigning full points to you for being such a great help. I will let you know when I actually end up doing this.
I will assign the remaining points when I close the request.
Thanks again

BI switching to new ECC 6.0 box from R/3 4.7 box, question on delta init?

Hi all,
Our BI has been already upgraded to 7.0. Currently connected to R/3 4.7.
Now a new box is made with ECC 6.0 and Oracle 8 which is a mirror copy of the r/3 4.7.Once the new box is ready the BI 7.0 connection will be switched from R/3 4.7 to the new box ECC 6.0.
My question is ...
In the R/3 4.7 the datasources were already initialized for delta..so the pointer for delta was already setup.
Now when we connect the new ECC box do I have to initialize delta again ? or would the new system recognize the pointer since it is a mirror copy from the old system?
pls advice

It´s a bit confusing what you write - I try to get your point:
- your 4.7 is running on Oracle 8 (VERY old, unsupported)
- you install a NEW system on ERP 6.0? Or do you upgrade your 4.7 copy?

Hi,
you would have added the new ECC source system to the BI.
I that case I think you need to initialize the Data again.
As all other requirements for delta like the pointer in delta queue might not be set for the new datasources.
I havent tried such thing till. but as per the concepts I understand You need to initialize the data

BIG Question regarding INIT Loads..I am scratching my head for past 2 days

Hello All,
I have one big question regarding the INIT load. Let me explain you my question with an example:
I have a datasource say 2LIS_02_ITM for which I ran the setup tables on JAN 2008. The setup table is filled with say 10,000 records. After that we are running Delta loads everyday till today (almost 30,000 records). Everything is going fine.
Imagine I lost a delta (delta failed and did'nt I do a repeat delta for 3 days, by then next delta came), Hence I am planning to do a Init load again without deleting / filling the setup tables. Now my question is :
1) Will I get the 10,000 records which got filled initially in the setup tables or will I get 40,000 records (that 10,000 + 30,000 records)
2) If it bring 40,000 how is that possible as I hav'nt filled the setup tables?
3) Is it each time I need to fill the setup tables to start the Init load.
Waiting for your guidance.........

Yes...to answer your question
But...agin I will suggest not to go by that method. Only one delta had failed so why do you want to wipe away the timestamp of the last init just becasue of 1 delta failure? it is possible to correct it
First of all i hope you have stopped the process chain or put a hold to Delta jobs
Now, To answer your doubt, about the status red ..See you mark the status red in each of the the data target before delting the failed request from there (I usually do not just delete the requests frm data targets - I mark them red and then delte it to be safe).
Do not forget to delete subsequent requests afterthe failed delta (agin I always mark them red before doing so)
Regarding the actual reuest itself...you need not mark it red in the monitor..You have got to correct this request and successful - it will automatically turn green.
If after successfully correcting the request, it still does not turn green, you can set qm status green. The next delta will recognize this a successful request and bring in the next delta (this happens in cases where you have the infopackage in a process chian when it shows green because subsequent processes were not completed etc).
Let me know in case you have any questions.

Generic Delta: Init, Full Upload and Deltas...

Dear All,
Last week on 10.04.2014 I've created "Generic DataSource with Generic Delta" and used CalDay as Delta-Specific Field and lower limit kept to blank and upper limit to 1. On 11.04.2014 I've initialized the Delta with Data Transfer using Process Chain: Time 1:15 p.m (Note: Posting was on)
see below screen shot:
Result: Process Chain was scheduled to immediate and it executed and initialized the delta and brought records as well. See below screen shot of RSA7:
Q: 1: Why generic delta current status is 10.04.2014, as I'v scheduled delta through process chain on 11.04.2014 @ 20:50: and why Total column is showing 0 records? Even I've checked Display Data Entries with Delta Repetition, but could not find any records?
Following is the InfoPackages which I created for Delta Loads and used in another Process Chain for Delta scheduled (daily @ 20: 50).
Following is the DTP used into Delta Process Chain:
On 12/04/2014 when I checked my InfoCube, and found that same number of records being loaded again despite InfoPackage and DTP were created as Delta, see screen shot:
On 12/04/2014 See below PSA table:
On 14/04/2014 when I checked InfoCube and I saw deltas being loaded successfully: see below screen shot:
On 14/04/2014 see below PSA table:
On 14/04/2014 see below RSA7 BW Delta Queue Maintenance screen shot:
Q: 2: Why am I unable to load the Delta records on the day(11/04/2014) when I initialized it with Data and why same number of records being loaded again on 11/04/2014?
Q: 3: On 11/04/2014, around 1:15 p.m I've initialized Delta with Data successfully and the same day (11/04/2014) was my first load of delta records (Time: 20: 50), could this be a problem? as the posting period was on when I initialized and I tried to load the delta on the same day?
Q: 4: Why the pointer is showing me Current Status: 12/04/2014 today and this time around I can find last delta records from "Display Data" option with Delta Repetition?
Q: 5: Have I missed something in the design or data flow?
Q: 6: How can I verify deltas records accuracy on daily basis; is it from RSA3?
or How can I verify daily deltas with ECC delta records?
Q: 7: What is the best practice when you load full data and initialized delta and schedule deltas for Generic DataSources with CalDay as delta specific field?
I will appreciate your replies.
Many Thanks!!!
Tariq Ashraf

I clearly got ur point.....But
If i have situation like ....." I loaded the LO data from R/3 with Init delta......then i loaded 5 loads of delta too.......due to some error in data now i am trying to load all th data......In this case if i do Full upload it is going to bring all the data till 5 th delta load .......If i do Init delta again it is going to bring the same data as full upload..........In LO while loading both Full load or delta init load we need to lock R/3 users....I believe we can load delta even after full upload by using "Init delta without data transfer"............So that wont be the barrier....then what is the difference or how should i figure out which load should i do.............If i am wrong please correct me.......
Thanks

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: 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 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.

How to do delta loading again based on delta init time?

Hi experts,
   in my case, I have delta init (2000 - 9999) which successed on 3.1 (it's huge data and time consuming) after that, we have delta loading per day.
   unfortunately, we do some wrong process when we get delta failed, it's cause some data missing in BW.
   3.5   delta success
   3.4   delta fail, do right delta correction (repeat delta)
   3.3   delta fail, do wrong delta correction
   3.2   delta success
   3.1   delta init success
   in this case, we miss some records in 3.3 's request. if I going to fix this problem, formal way it should do delta init again then schedule daily delta. but since delta init is successful and need lot of time.
can I advoid do delta init again?? just do delta again base on delta init (3.1) ??
   thanks in advanced

Hi jie,
Whenver you incur a Failure when data is being loaded from R/3 systems to BW via DELTA. It means that the Records were not transferred during that load to BW from R/3.
Hence the next load is always a REPEAT DELTA.
It may happen at times that you may miss few records in this.
If so, then in that case do a repair request from infopackage scheduler and then load the missed records.
Then again start off with Delta and loads should not have any problems.
Else you need to do a Re-Init of Delta. And re - do all over again.
Cause every time we miss the records we need to bring them in via repair request.
Hope this helps.
Thanks,
Pradip Parmar

0HR_PY_1_CE - Delta init with time limitations

Hallo everyone,
I want to use the Content-Extractor 0HR_PY_1_CE to transfer payroll data into SAP BW in delta mode.
As the source system is running payrolls for a very long time allready, I would like limit the data by time. Pittily the extractor does not support filtering by time in delta mode. (Found this on SAPs help pages and also tried to set start and enddate ... no luck as assumed.)
So I had a look at the source systems customizing, but the only setting regarding a time frame for extraction I found is the one for PT-data. (Transaction SBIW -> Settings for Application-Specific DataSources (PI) -> Human Resources -> Define Time Frame for Transfer)
Within the PY-Customizing there is no option to limit the extraction interval.
Is there any other way to limit the extraction to a specific time frame when loading data via 0HR_PY_1_CE?
Thanks a lot in advance and regards
Chris
Edited by: Christian Baum on Jul 27, 2010 12:15 PM

Hi Yuvaraaj,
thanks for taking the time to answer my question.
For time selection I use the extractors default datafields: BEGDA and ENDDA.
Pseudo-delta might be an option IF the two fields you mention are processed in the extractors selection logic. I actually don't know and would need to take a closer look on the extractors programm logic.
Anyway my goal is to stay as close to SAPs standard as possible.
Pittily the extractor does not support filtering by time in delta mode. (Found this on SAPs help pages and also tried to set start and enddate ... no luck as assumed.)
I had another look at [SAPs documentation for 0HR_PY_1_CE|http://help.sap.com/saphelp_nw70ehp2/helpdata/en/6a/cccc6015484464b25605375a5db965/content.htm] and have to recall the statement above.
As there is no restriction mentioned about delta and time selection there must be a way to pass a time frame when initializing the delta.
I tried the following:
1. I startet an Infopackage in full mode with the follwing filter criteria: BEGDA = 01.10.2009; ENDDA = 31.10.2009
The extractor dilivers ~60000 records; their inper is allways 10.2009. -> Selection worls fine
2. I started an Infopackage in delta init mode and exactly the same selection criteria as the full mode Infopackage and i receive millions of records whichs inper is spread over several years.
So the time selection is definitely not working in delta mode.
Are there any customizing settings I missed in the OLTP system?
Regards
Chris

How to see the init load in bi 7.0

hello frnds,
In bi 7.0 when v load data it show the full load and delta load option only,,so my question is, if delta load r there then definately init load also avilable,so where is that init load,,plz guys tell me where is that option,,
2nd question is about compression in bi 3.5,,after loading data into infocube when i do compression it ll not work,,why i dont know ,,plz help me
Thanks
Rosy

Hi Rosy,
Init with data load is Full upload + Delta Enables. Once you run this it will fetch entire records from the Source, delta will be automatically enabled and next time onwards only delta will be coming to BW.
Before you can request a delta update, you must first initialize the delta process.Delta initialization can only be simulated for DataSources from SAP source systems if the DataSource supports this.
I hope the below link will be helpful,

CRM Init load failure Errors In Source System 340

Hello
This is my first question on SDN.........could anyone help me please????
When I am attempting to do an Init load to ODS 0CRM_PROH and to MD Infoprovider 0CRM_SRVGUI, using Infosource 0CRM_SERVICE_PROCESS_H the load is failing and I get the message Errors In Source System 340.
Version is BW3.5 and CRM4.0
Thanks
Emma

Thanks Venkat
I have considered this but could you please explain the following:
If I start a full load at say 10am. It finishes at 11am. If I then do an init no data at 11.05am after the full load has finished. then I do a delta. Does this mean that my delta will pick up data only from when the init no data was done and set the timestamp?
So I will lose any data between 10am (when I started full load) and 11.05am (when I ran init no data)?

Need of Change log deletion for a DSO, when DTP delta Init with Active Tabl

Hi,
Thanks for your time, please help me with the following
Scenario: I have Cube1 being updated from DSO1 with DTP delta, for quite some time. As per new requirement, I would need to create new data mart such that Cube2 gets updated from DSO1.
In order to Configure the delta, I am Considering Following options, please let me know, which one is right one.
Note: DSO1 is in Overwrite Mode.
Create one DTP with update Mode "Delta" , and "Active Table". I knew Delta Changes are captured in change log, but my understanding is, when you execute the DTP for the First time, it fetches the records from Active Table. And from 2nd Run onwards the very "same DTP" without "any changes" get the records from change log, even if we choose "Active Table".
is my understanding is Right?
Do I have to consider deleting the change log, because DSO1 is in Production from quite some time which is in Overwrite mode?
Do I have to create a DTP with Delta and Active Table, run the dtp Once(Init), then choose "Change Log for subsequent runs explicitly
please help me with these. I have reviewed many sap help articles and sdn threads but none of them were helpful. all of them explains, difference b/w active table and change log table, also gives scenarios like use a full DTP and then 2nd DTP with Delta without Data transfer. I am not looking for that kind of details.
Appreciate any help, Thanks again

Hi Uma,
Thanks for your response.
to your question, If I need to load all the data from DSO1 to Cube1, answer is NO. if you read my post once again,
Existing Flow is : DSO1 --> Cube1 (Means, Active Table and Change Logs of DSO1 already Filled Up)
Requirement is: DSO1 --> Cube2. (Need to Init the Delta, and Detlas going forward)
My Questions:
(1) Imagine, DSO1 has 10 requests, so we see resepctive data in Active Table as well as Change Log. As a matter of fact, Data is being updated to DSO1 in Overwrite Mode, so all the changes(10 requests equivalent) would be captured in Change Log, which in turn helpful / used when we do Delta from DSO1 to any Cube, in my case, it used to update to Cube1. As per new requirement, it needs to update to Cube2.
My assumption is, if I choose "Active table and Delta in Extraction Tab" in DTP, During First Run (Delta Init), Data would be fethed from Active table. And the 2nd Run Onwards, delta records would be fetehced from Change Log automatically, even if we don't change the selection from Active Table to Change Log.
Is My Assumption Right?,
in this process, Do I have to Delete Change Log
(2) Do I have to Explicitly change DTP setting from "Active Table to Change Log" Once Delta Init has been run with setting "Active table" inorder to get Deltas from DSO1 --> Cube2 ?
Appreciate your help

Init Loads

Say i run a Init Load for period 200601 to 200612 .After Init i run delta which will carry same selection conditions.Now if data changes for period before 200601 or after 200612, will those changes be captured by the delta

Hi Amit,
The same init selections apply to the delta loads so any transaction not under the selected date range(init selections) will not be captured by the delta loads.
So to your question the 2007 data will not be loaded under delta loads.
The data or records that fall under the init selection range only will be captured & updated into the BW system.
Regards
