Generic Delta with Numeric pointer.

Hi Experts,
We are using a generic delta for a Standard Master Data Attribute Data Source. Since it is standard by default it has the Numeric Pointer and the Additive Delta in the settings.
When a delta extraction is done with this option it does not bring any changed records it just brings the newly added records.
We are not able to change to the other Delta options available in that screen.
Could you guys help us with this issue.
Thanks
Sandhya

Hi Harvinder,
The answer you gave was very helpful.Thanks for all your help so far.
Due to some restrictions from our BASIS team, We are not able to Check the 'Change Document' for (AEDAT) Changed on field. There are other fields in the same Data Source which are Delta Enabled and they also have the 'Change Document' Checked. Could we use one of those fields in our Delta. If yes what changes do we have to make. If you can, Can you give a brief step by step how to make the changes.
Also we are not able to change anything in the Generic Delta tab. At times it is giving an error, other times it does not get saved when we go back it is unchaged. May be we are doing something wrong.
Regards,
Sandhya

Generic Delta with numeric pointer (Without safety interval and no field)

Hi
We have problems with Generic Delta extraction. Our previous Dev has created the data source with numeric pointer as the data source without any safety interval and without any field for numeric pointer selection even we have the date field (creation and change dates in view)....
He created the generic delta with numeric pointer and Additive delta selection on top of view (EKKO,EKPO and EKKN). So we are missing lot of records. Now I need to fix this asap, I have done generic delta with timestamp and cal day with change/creation date.
Now in order to fix our delta loads should I use the cal day as the delta pointer with change or creation date already available or is it ok to use numeric pointer with additive delta and safety lower limit as 10 or 20 with upper limit blank?
Also Should I use any field in the field nm section or is it ok to leave it blank ? Please advice...
Note: I checked the missing delta records in ECC and the change timing is in the afternoon and our load time is only night...We also have several other data sources with same settings (numeric with no safety and no field) but it is not giving any issues.
Thanks

Hi Ganesh ,
I'm a little confuse,Why are you not use LO Delata for it?

Generic delta with time stamp

Is it possible to work with generic delta with timestamp without time chracterstics , and calday with out date feilds.
PLZ can any one provide reply to my thread.
Edited by: aumdeepa on Aug 5, 2011 11:47 AM

If it failed in BW (request is red) and you do a delta - system will ask to mark it a 'repeat' because the last one failed. When you choose 'repeat', it is going to let the extractor know that it is a repeat delta.
In this case, it will extract data from 25th to current date (both last and current delta).
Repeat delta will work the same, just that the lower and upper limits will be applied to the selection of the delta field.
Lower limit -> adjust back the lower selection value by this value
upper limit ->Adjust back the upper selection value by this much.
upper limit 1, lower limit 1 (by the way lower limit isn't usually applicable in real situations)
Ran delta on 20th first time
Select all data upto 19th (adjusted due to upper limit)
Ran again on 23rd
Select from 19th (ie 20 - 1 due to lower limit 1) upto 22nd (ie 23 - 1 due to upper limit)
Ran on 27th
Select from 21st (22 - 1 due to lower limit 1) upto 26th (27 - 1 due to upper limit) and so on.
Repeat delta will follow this logic but will also bring the selection that was executed in the last delta run.
Hope it clears.

Generic delta with function module

Hi Gurus,
Is it possible to create a generic DataSource with delta support using function module following the queue delta mechanism (u can get some function moduel in MCEX function group, and check the outbound delta queue before and after update in transaction smq1.
I can store the delta data using qRFC and collective update mechanism. but I don't know how to create a generic data with delta and how to attach a rfc destination (& logical system) to the data source. The Source system information is stored in the table "ROOSGEN". Is there any configuration setting required to do the same.
Regards,
Jugal

Jugal,
What I understand you to be asking is if it is possible to create a generic delta extractor which uses the delta queue. If this indeed is your question the answer is yes.
First you need to create your data source so it is visible via tx RSA5 and need to make sure that the delta type (ie ABR, AIM)is set appropriately for the datasource.
The issue however is determining from where you will associate your delta hook (when will you write to the queue)? I have in the past utilized BTE's, Business Transaction Events to write information out to the delta queue, you can see a list of available BTE's in your system via tx FINF.
Once you find a place to write your deltas from you call the below FM with the appropriate datasource.
RSC1_TRFC_QUEUE_WRITE.
Once you have done this the standard BW extractor for deltas will pull the information from the delta queue. But from what I understand you just want to know how to associate the data with the delta and that is the FM listed above.
Hope this helps,
Cheers,
Scott

Generic Delta with Timestamp Field

Dear SDN Team,
We changed one of our HR datasource from FULL to DELTA with Timestamp(TMSTMP)-Time Stamp(UTC).
Which Delta we need to take Timestamp(Local) or Timestamp(UTC)
Our Generic Datasource is based on Function Module.This data source contains HR Hours Data i.e Direct Hours & Indirect Hours.
With interval settings has
Safety Interval Upper Limit - 'Blank' .
Safety Interval Lower Limit - 1800
New status for Changed Records (Selected)
It is a HR Generic Data Source.
We are creating the records in PA30,PA40 and going to take the records from PA0000,PA0001
Delta type for this DS is "AIE" as our delta type process for our DS.
I am trying to load the INIT to Cube,but its not allowing to load,saying with 'AIE' delta type its not possible to load to cube.
I changed the delta type to 'ADD' then the safety interval limits changed to
Safety Interval Upper Limit - 1800 .
Safety Interval Lower Limit - Blank.
Additive Delta (selected)
Is it possible to load the Generic Delta Time stamp to Cube?
Please let us know what are the settings & delta type needs to be there to load the Generic Delta Timestamp to Cube.
Your suggestions are really appreciated.
Thanks and Kind Regards,
Lakshman Kumar G

Generic delta with timestamp

Hi All,
i have created a generic datasource using tables vbrp,vbrk.mara,marc,knvv.. to get the sales data for planning.Here i have document created date and time.So i'm concatinating these 2 date and time fields into timestamp which is of format yyyymmddhhmmss.Finally i'm using this timestamp to extract data .
So is it the right way to pull the data using timestamp and what is the timezone i need to specify as the servers are in india only.
or any other way to proceed.
Thanks

Hi Siva,
U mean.. is ur MKPF is having the TIme stamp field in that? or this table has got enhanced with the TIme stamp field..?
do let us know these details..
Why dont u try using any other fields like changed on or some other fields which will satisfy ur requirement..?
Is ur Init is done successfully?... and do u see an entry in the table ROOGENDELTM table....
This table will be having an entry for the generic extractors which are with the Delta's..
Thanks

Generic Delta with Two fields

Hi,
Can it be possible to have Delta on two fields in Generic Data Source?
If yes, Please let me know the Procedure.
Thanks,
Ram.

hi,
generic data source is nothing but if u used one data source to upload the data to one ods. at that time u want the same data source for next cube also.that time u crete the generic data source and create transformation ods to cube and also create the dtp ,upload the data.
delta means its filter the same records present in next time.
1.create data source and infopackage.
2.upload the data to datasource(psa).
3.create ods.
4.create transformation.(use that data source).
5.create dtp.
6.execute the data.
7.create cube.
8.right click the ods.
9.create generic data source.
10.right click the ods create transformation(use torget as cube)
11.create dtp.
12. that will have full or delta updates .
13. use delta update.
14.execute the data.
if its helpfull assign points.
thanks.

Generic delta extractor on view with ALE

Hello.
Extractor 0RT_WRF1_ATTR has type V and generic delta setting Numeric Pointer. Generic delta field is empty. Delta Process = A (ALE Update Pointer (Master Data)). ALE delta setting includes all fields of extractor structure. But changing one of these fields doesn't push new records into datasource.
Can you please explain, how generic delta works with ALE pointers аnd why no data is delivered?

CC,
Check on deletion data available in table(with any indicator updated) or not available in table.
If not available, you can not get delta through generic datasouce.
Hope it Helps

Geneic Delta Numeric Pointer

Hi,
I have to creating Generic Data Source based on the SAP CRM Table "CRMD_CUSTOMER_H:Transaction - Customer Extension " in this table doesn't have any time filed and cal day field, so i go for Numeric Pointer for delta loads.
This is the unique number GUID of a CRM Order Object :4D90ECFF75034191E1008000AC100A37.
but how to set the Safety intervals for these info object?
Thanks

hi,
Yes....... you are right......
I have created generic ds with numeric pointer without safety interval..it works fine.
Solve my problem
Thank you.

Numeric Pointer Option on Generic Delta Screen

Hi, I was just wondering if anyone could help with why the option for 'Numeric Pointer' on the 'Generic Delta' screen in datasources is missing. I only have the option for 'timestamp' and 'calendar day'.
Thanks

Hi,
If you are trining to create a Generic delta with FM, you can't find the option "Numaric pointer".
Please check this link.

Generic delta not working with '0calday' change pointer

I have created a generic datasource based on a database view and extracted data with afull load infopackage into BI. Then, I configured the generic delta with a date field and 0calday type. Set the safety interval of 1 day as a lower limit. Saved the datasource in R/3 and Replicated and activated the datasource in BI. Done some changes to a record in R/3.
After that, I created an Init delta infopackage (with data) and extracted the data with the same number of records as extracted in the full load. Note that all these were done on the same day.
If I have done something wrong by doing it on a same day, I should get 0 records.
Why did I get the same data with a delta init package? I wonder the generic delta is configured correctly or not? Please tell me where I have gone wrong. Thanks..

Hi Shiva,
While running the delta init, you have option of without data transfer and, with data transfer.
I am sure, you used with data transfer and thats why got all those records same as full load.
U can use different options like.
1. DO the init without data transfer and then do the full load, and then run delta everyday for delta records
2. Do the init with data transfer then no need to do the full load and the subsequent delta will take care day onwards,
I guess your are good to do the delta load by tomorrow.
Thank-You.

Generic delta extractor for BW

Hello people!
I'm developing an extractor for BW with Generic delta with the field AEDAT.
In function module for the extractor, how can I identify this delta?
I have to select the table ESSR with this field and I don't know how to identify this field.
Thanks in advance!
See ya!

Define a range field like
ranges : l_r_aedat for <tabname>-aedat.
In your FM
LOOP AT S_S_IF-T_SELECT INTO L_S_SELECT WHERE FIELDNM = 'AEDAT'.
MOVE-CORRESPONDING L_S_SELECT TO L_R_AEDAT.
append l_r_aedat.
Then when you do selections :-
Select * from <tabname> where
and aedat in l_r_aedat.

Regarding generic delta numeric pointer

Hello gurus,
I have done changes in RS02 --> vbak table on field VBELN > using numeric pointer>new status of changed records.
I have set changes for Delta pointer too e.g 50000 in ROOSGENDLM .
I have entered sales data in VA02 transaction. Say document 50006 has been created. But records are not updated to delta queue during delta load in BW
For LO, we are scheduling job for updating records from extraction queue to delta queue.
Do we need to schedule any job?? So that new/changed data is updated to delta queue.
Please let me know
Thanks,
Sonu

Hi
1)It will count numeric pointers and if the changes in R/3 create a new record with a new numeric pointer which is different then the orginal record then it will get pulled as delta.
2)in numeric pointer option you can give the field name of the table which can be a any numeric or char field like document number.
3)If the posting is happening at the same time then depending upon the offset given it will come in the next load.
you will never miss any delta if lower limit is set properly.
4)If lower limit is 10 then the last 10 records get pulled again.Thats why you are asked to load such kind of delta loads to a DSO in overwrite mode.
5)use it only when you have a field like document number or a numeric number which is created when a record is changed or created.You can have a documnet number as numeric pointer if you intrested only in new records and not the changes happening to them.
To capture the changes you may need some other field like changed on date.

Generic delta has problem with delts pointer time stamp

Hi All,
We have generic delta data source with Delte pointer as Time stamp. We have not used any safety limits. We are loading the data to DSO and using Additive delta. But the problem is when delta flag is set, there might be a case where some records still being inserted to table with lower time stamp. These records are not being fetched in next delta.
We are planning to keep a safety upper limit of 5 min so that those records can not be missed. But we have a doubt as it is a Additive delta duplicate records will be loaded. If we make the delta to 'new status to changed records', it is going to work?? Any other things we have to check when we make this changes??
Thanks
Haaris

Hi
If you had selected additive delta then you can load data to DSo with addition mode only. No overwrite possible.
If you want to select new or changed status then you can load to DSO with overwrite mode only.
Additive or changed delta depends on your requirement because if you want to add data to the DSO then you can go ahead with additive otherwise you have to use DSO with overwrite mode only.
You can either give safety upper limit or lower limit but if you give safety lower limit then you can only load data to DSO with overwrite mode because there could be some duplicate records.
Hope it clarifies.

How can we get changed records in delta in case of numeric pointer

Deall All,
Thanks to all of you gurus i have been able to Get delta update for my query.
There is one last issue how can i include changes records in my delta update when i am using numeric pointer for data selection.
or
It can only be doen by time stamp.
can you explain me details of using time stamp.
Thanks & regards,
Gaurav Sood

Dear Gaurav,
Here we have three options for delta updation:
Time Stamp:   If we want to update change in the records with respect to the time interval then this option is selected.
Calend. Day:   If we want to update change in the records with respect to day to day basis then this option is selected.
Numeric Pointer: If we want to update in case of record which is completely new with respect to Field name then we use this option.
And we have got some settings like:
Safety Interval upper limit:
This field is used by Data Sources that determine their delta generically using a repetitively-increasing field in the extract structure.
The field contains the discrepancy between the current maximum when the delta or delta init extraction took place and the data that has actually been read.
Leaving the value blank increases the risk that the system could not extract records arising during extraction.
Example: A time stamp is used to determine the delta. The time stamp that was last read is 12:00:00. The next delta extraction begins at 12:30:00. In this case, the selection interval is 12:00:00 to 12:30:00. At the end of extraction, the pointer is set to 12:30:00.
A record - for example, a document- is created at 12:25 but not saved until 12:35. It is not contained in the extracted data but, because of its time stamp, is not extracted the next time either.
For this reason, the safety margin between read and transferred data must always be larger than the maximum length of time that it takes to create a record for this DataSource (with a time stamp delta), or it must display an interval that is sufficiently large (for determining delta using a serial number).
Safety Interval Lower Limit
This field contains the value taken from the highest value of the previous delta extraction to determine the lowest value of the time stamp for the next delta extraction.
For example: A time stamp is used to determine a delta. The extracted data is master data: The system only transfers after-images that overwrite the status in the BW. Therefore, a record can be extracted into the BW for such data without any problems.
Taking this into account, the current time stamp can always be used as the upper limit when extracting: The lower limit of the next extraction is not seamlessly joined to the upper limit of the last extraction. Instead, its value is the same as this upper limit minus a safety margin. This safety margin needs to be big enough to contain all values in the extraction which already had a time stamp when the last extraction was carried out but which were not read. Not surprisingly, records can be transferred twice. However, for the reasons above, this is unavoidable.
Data Source Is Real-Time Enabled
The 'real time enabled' indicator determines whether a delta-enabled Data Source can be used as a supplier of data for a real-time daemon.
And there are two options provided like
1)     New Status for changed records:
If you select this option each record to be loaded delivers the new status for the key figures          and characteristics. DataSources with this delta type can write to ODS objects or master data tables.
2)     Additive Delta:
The key figures for extracted data are added up in BW. Data Sources with this delta type can supply data to ODS objects and Info Cubes.
Hope this helps u..
Best Regards,
VVenkat..
