Delta load update

how can we enable the delta load update

Hi,
If its a delta capable DS, you have to initailize it once. After that delta records will be acummilated in delta queue and you can pull into BW.

Inventory - No Marker update is set for delta loading, any impact ?

Dear all,
Since several days the daily delta on inventory cube is done with flag "no marker update set".
What are the possible issue ?
Do we have to reload the data or can we just set the flag as unchecked ?
Thanks for your help
Best regards
Christophe

Hi,
Pl check below
Marker Update is used to reduce the time of fetching the non-cumulative key figures while reporting. It helps to easily get the values of previous stock quantities while reporting. The marker is a point in time which marks an opening stock balance. Data up to the marker is compressed.
The No Marker Update concept arises if the target InfoCube contains a non-cumulative key figure. For example, take the Material Movements InfoCube 0IC_C03 where stock quantity is a non-cumulative key figure. The process of loading the data into the cube involves in two steps:
1) In the first step, one should load the records pertaining to the opening stock balance/or the stock present at the time of implementation. At this time we will set marker to update (uncheck 'no marker update') so that the value of current stock quantity is stored in the marker. After that, when loading the historical movements (stock movements made previous to the time of implementing the cube) we must check marker update so that the marker should not be updated (because of these historical movements, only the stock balance / opening stock quantity has been updated; i.e. we have already loaded the present stock and the aggreagation of previous/historical data accumulates to the present data).
2) After every successful delta load, we should not check marker update (we should allow to update marker) so that the changes in the stock quantity should be updated in the marker value. The marker will be updated to those records which are compressed. The marker will not be updated to those uncompressed requests. Hence for every delta load request, the request should be compressed.
Check or uncheck the Marker Option:
Compress the request with stock marker => uncheck the marker update option.
Compress the loads without the stock maker => check the marker update option.
Relevant FAQs:
1) The marker isn't relevant when no data is transferred (e.g. during an delta init without data transfer).
2) The marker update is just like a check point (it will give the snapshot of the stock on a particular date when it is updated).

Question for delta loading, why can not update existing record in cube

Hi, Gurus,
I load data from a flat file into one infocube with delta loading option, and in the related datasource, i chose 'additive delta' option.
However after delta initial and delta update, when I checked cube content, I found that there are 2 records with the same characteristic value (just like duplicated key), and my expectation is to sum key figure with the same characteristic. Who can help me on that?
BTW: when I check delta queue, why there is not any queue?

Hi,
In uploading of flat file , If you are able to capture the changes to the previously loaded records, Then you can follow the additve delta. So it decreases the time of uploading .Only changed or new records will be uploaded every time.
If you are not able capture the changes in flat file ,Every time you have to do full upload ,Before this delete the contents of Infocube. (Assuming there is no ODS B/W Infocube and Flat file).
With rgds,
Anil Kumar Sharma. P

Batch update vs. Delta Load

Hi expert!
My understand of the delta load is that it only captures the changes from online posting, not batch posting. Is this true? If so, how to reflect the changes made from batch postings in BW? We have a batch standard cost adjustment process which runs a few times during the year. Each time, when this happens, I would like to have my BW backlog cost updated with this new cost. What will be a right way to capture this kind of the changes in BW?
Sharon

Sharon,
The delta process depends upon the extractor, in most cases the extractors will pick up changes to the source data,And you can load the delta to BW. Batch process should not matter as long as the events which trigger the delta is affected. For instance, In Logistics extractors, you can see the events in LBWE transaction.
Please check the extractor, I guess it will pick up the changes irrespective of the process which was used to update the transactions.

About delta loading for master data attribute

Hi all,
We have a master data attribute loading failed which is a delta loading. I have to fix this problem but I have two questions:
1. how can I find the those delta requests because I need to delete all these failed requests first, am I right ? Master data is not like cube or ods that we can find the requests in Manage, for master data how can we find them ?
2. Could you please let me know the detailed procedures to perform this delta loading again ?
Thanks a lot

Hi...
1. how can I find the those delta requests because I need to delete all these failed requests first, am I right ? Master data is not like cube or ods that we can find the requests in Manage, for master data how can we find them ?
Look.....for master data.....no need to delete request from the target..........just make the status red.......and repeat the load.....But problem is that master data sometimes does'nt support Repeat delta..........if u repeat......then load will again fail with Update mode R.........in that case u hav to do re-init.......
1) delete the init flag.......(In the IP scheduler >> in the top Scheduler tab >> Initialization option for source system)
2) Init with data transfer(if failed load picks some records)..........otherwise .....init without data transfer.....if the last delta failed picking 0 records.......
3) then Delta.......
2. Could you please let me know the detailed procedures to perform this delta loading again ?
1) Make the QM status red.........to set back the init pointer.......
2) Repeat the load.....
After that.........if again load failed with Update mode R.....
1) delete the init flag.......
2) Init with data transfer(if failed load picks some records)..........otherwise init without data transfer.....
3) then Delta.......

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 are not working: 0FI_GL_10 With enhancement : HR Data in source

Hello Friends. Thanks for your answer on theory which I know, Please help me with this situation. I read all the sdn response to my message and have below for your suggestion
QUES1: Why the 0RECORDMODE is not coming in Standard DSO and hence it is not there in Transformation in between Infosource and DSO. What do I need to include 0RECORDMODE in standard DSO. What is the correct OSS to Implement on SP 10 to solve this.
Ques2. As suggested by you If I run the Delta loads after waiting for 1 hour of Init load. say init load was done at 11 am . i will do the delta at 12:10 am to psa via Infopack and then wait for an hour to run the DTP from PSA to DSO. Delta Records come in but it also bring in the records in DSO that are not changed from about 7 hours in ECC. and make our total Balance incorrect.
Ques3: We have this Cocatenation of Keys in DSO since we exceeded the total number of 13 key in DSO.
Cocatenation#1 GL ACCT and CHRT OF ACCTS
Cocatenation#1 SEGMENT AND CONT AREA
Cocatenation#1 Version, Value Typem, Valuation view, Currency Type.

Since business want to include HR Data in Keys Like Employee Number, Emp Code, EMPSPIMCODE. Payroll ID and I can not remove these fields from Key in DSO as per the business.
Also the above fields GL ACCT , CHRT OF ACCTS, SEGMENT, CONT AREA
exist in Data FIELDS OF DSO. so what are the steps to modify the design to fix this asap.
Please email me at [email protected] if you have any docs to resolve the above
Thanks

Did the full load bring all records from sourcesystem to PSA?
Was this an issue with the first delta you have tested ?
Concatentaion of multiple keys into one should not be an issue here as that must have been happening in DSO and delta brings incorrect records to PSA itself.
Are you validating delta records against FAGLFLEXT inputing the timestamp value or RSA3 ..how ?
Check if this note helps
Note 1002272 - NewGL-DataSource 0FI_GL_10, 3FI_GL_*: Missing record.
Is delta bringing incorrect records to PSA or DTP brings incorrect records to DSO from PSA ?
May be you should revisit the logic behind for the enhancement of 0FI_GL_10.
I am facing a similar issue as well but here delta doesnot even bring a single record ( ODS has 20 keys )...will update if resolves and you do the same.

Hello,
As per the screen shot provided below, data soruce belongs to LO, so first check in RSA7, whether it has got mark in RSA7, for which you have entries in RSA7 against the data source. If you are not able to find the data source in RSA7, then you need to set-up the update methods, based on the requirement.
1) Direct Delta
2) Queued Delta
3) Unserialised V3 Update
Once it is done, Delete the Previous Initilisation, again perform the Re-Init With Out data and now schedule the Delta Data Loads
Hope this may Help you.
Thanks

Delta loading and Process chain BI

Hi experts,
Two Issues.
1)As i am loading FI data into dso through a process chain which includes Start process>Delta infopackage(which gets data upto psa)>Delta dtp-->Datastore activation.
But infopackage is picking up deltas but DTP is picking up all the previous records plus deltas.
100 records -- 1st day throught Intialization of Delta with Data Transfer
2 delta records -- 2nd day
But DTP is picking up 102 Records on the 2nd Day, which means it is also picking the old records as well.
The DSO must have just 102 records but it is having 202 records.
2) A process chain in running daily as scheduled , but I rescheduled with new scheduling options without deactivating the Process chain.
My Question is
Will the Process chain run for the OLD and the New Schedule or
Is it going to run for new schedule or old one?
or
will I face any Problem because I did not deactivate and made changes to the Change.
Please help me in this matter.
Thanks in advance.
Bhadri.

First query:
I believe that u have used FUll update type DTP is instead of the Delta DTP.. Please cross check the Update mode of the DTP once.
To resolve this issue, delete the total content of the DSO as u have Init and delta loads in PSA. And then using the Delta DTP of the Process chain, load the data. It will extract the total cotent what ever is there in PSA, and later the same DTP will act as the Delta type and will pick the data from the New request of the PSA.
Second Query:
Its always suggested to deschedule the process chain before changing the schedule timings. When ever u do this type of scheduling, just check how many number of JObs available in Schedule mode, if u can see more than one, then delete the older one and keep the new one as it is.
But I always suggest you to deschedule the process chain and reschedule PC with the new timings and then activate the same.
Thanks

Error in delta load of 'Customer Group' from R/3 to CRM

Hi Experts,
I added new 'Customer Groups' in R/3. But this is not being updated in CRM. Do I have to trigger initial load again through R3AS or should I create new Customer Groups in CRM?
The BP delta load BDocs are stuck in SMW01 due to this change. Also, if I need to do the Initial load of Customer Group, which object do I need to do the load for? Is it dnl_cust_sales?
Please help as it is a Production issue.
-- Pat

Hi Pat,
Use object 'DNL_CUST_SALES' to download Customer Group from R/3 to CRM.
Use R3AS4 transaction to execute the same.

Issue in the Delta load using RDA

Hi All,
I am facing an issue while trying to load delta using RDA from R/3 source system.
Following are the steps followed:
1. Created a realtime Generic Datasource with timestamp as delta specific field and replicated it to BI.
2. First I have created the Infopackage(Initialization with data transfer) and loaded upto PSA.
3. Created a standard DTP to load till DSO and activated the data.
4. Then created a realtime delta infopackage and assigned it to a Daemon.
5. Converted the standard DTP to realtime DTP and assigned the same to the Daemon.
6. Started the Daemon, giving an interval of 5 minutes.
In the first time, Initialization with data transfer is taking the records correctly. But when I run Daemon for taking delta records, its taking all the records again, i.e. both the previously uploaded historical data and the delta records).
Also after the first delta run, the request status in the Daemon monitor, for both Infopackage and DTP changes to red and Daemon stops automatically.
Can anyone please help me to solve these issues.
Thanks & Regards,
Salini.

If I understand you correctly you Initially did a full load. Yes? Well next you need to do intialise & after that delta.
The reason is that if you will select delta initialisation & initialisation without data transfer- it means delta queue is initialised now & next time when you will do delta load it will pick only changed records
If you will select delta initialisation & initialisation with data transfer- It means delta queue is initialised & it will pick records in the same load.
As you know your targets will receive the changed records from the delta queue.

I take it the infopackage has run successfully? Did you check? If it has and the error is on the DTP then i suggest the following.
At runtime, erroneous data records are written to an error stack if the error handling for the data transfer process is activated. You use the error stack to update the data to the target destination once the error is resolved.
To resolve the error, in the monitor for the data transfer process, you can navigate to the PSA maintenance by choosing Error Stack in the toolbar, and display and edit erroneous records in the
error stack.
I suggest you create an error DTP for an active data transfer process on the Update tab page (If key fields of the error stack for DataStore objects are overwrite On the Extraction tab page under Semantic Groups, define the key fields for the error stack.) The error DTP uses the full update mode to extract data from the error stack (in this case, the source of the DTP) and transfer
it to the target that you have already defined in the data transfer process. Once the data records have been successfully updated, they are deleted from the error stack. If there are any erroneous data records, they are written to the error stack again in a new error DTP request.
As I'm sure you know when a DTP request is deleted, the corresponding data records are also deleted from the error stack.
I hope the above helps you.

Delta load to ODS taking too much time

Hi,
I have one delta load running everyday to ODS .its getting data from R3 & its taking too 3-4 hours daily.due to this data is not getting updated in cube on time and there arises issue with data in Reports
Please let me know what are possible solution to check this ODS Delta load and improve its loading time
thanks
nilesh

Please check if the extraction is taking more time in R/3 or data loading is taking more time in BW. If R/3 extraction is taking is more time, try creating indexes on R/3 tables.

Issue with delta load from R/3 to BW

Hi frnds,
There is a standarded D.S 2LIS_05_ITEM in R/3. Evereday We extraceted data from R/3 to BW based on this standard Data Source with delta load.There are two fields ZX and ZY in BW ,some times the data haven't extracted for this 2 fields in BW with the delta update.But some times this 2 fields properly extracted in to BW with the same delta update.
Why is it happen like this ? Please give some inputs on this.
Regards,
Satya.

Hello,
if its a standard field then its getting populated in correct way.
if its custom field then you need to analyze the records for which its getting populated and for one which its not.
Quite possible that some cutomization in CMOD results in this behaviour.
Also,check underlying tables to see the correct values.

Problem in delta load with Z field

Hello Experts,
We have CRM 5.0 system and as per the requirement we have
added ZFIELD to BUT000 table. This field is added to BUT000 via EEWB – Easy
Enhancement Workbench. This field is also BW enabled.
BW enabled means – this field is used / available to BW
extractor for further analysis.
We update this ZFIELD with custom program – FM BUPA_CENTRAL_CI_CHANGE.
When full load is done – data flows to BW correctly, ZFIELD
values are reflecting correctly. But when we are doing delta load it is not
working.
If we use BP t-code delta works perfectly. So issue from BW
side is ruled out. The FM BUPA_CENTRAL_CI_CHANGE is not triggering the change
record for this BP. But then I don’t see any other FM / BAPI to use so that
change record is also created.
Could you please provide any pointers or any checks to
overcome this problem?
Thanks in advance.

Hi Ashtankar,
When you are changing the attributes(say ZFIELD) and save the transaction in BP, Is this updating the CHDAT(Change date) in BUT000?
If the change date is being applied, then Delta shouldnt be a problem - if you are using datasource 0BPARTNER_ATTR.
In order to check if the delta is being captured or not, you could use TCODE RSA7. Also, this brings the Doubt when you say Full load works while delta doesnt, try Re-initializing the datasource from BW after Datasource replication - because there have been some changes effective in Source system which the BW system/Delta queue might take into consideration.

Thejas K
