ALE Delta vs Generic Delta

Hi Gurus,
Can we set only ALE delta for master data attr/text extractors. Can we not set generic delta for master data extractors. If yes can you provide some master data extractors which use generic delta?
Regards,
Rajesh.

Hi, if we are loading master data from R/3 to BI system we will select change pointers in BD61 . ROOSGEN table contains the message types based on that message types change pointer will work. In TBDA2 table we can activate and deactivate the message types; in active column X means message type is active.before activating that field will be in blank once we will activate the it will converted it to X.

Generic Delta 2

Dear Expert
I have a z Table consisting fields like company code , change date, etc.
I have created a generic delta using change date as delta field.
A program loads data to this table.
Lets say I loaded all data for company code 1000 and there are other company code data I also need to load but have not done so.
I replicate the datasource to BI 7.
I have read guides on Generic delta and need clarification on its mechanism in more detail.
========
1. Do we need to Initialize Delta for Generic Delta?
2. If my infopackage used for the init is change date of yesterday, what happens when some days later, I load company code data 2000 into the z table and these data has change dates earlier than the init date?
3. Does init work like this : lets say the data selection in the infopackage used for the init is :
company code = 1000
change date = yesterday.
the 1st delta infopackage will be based on the change date of yesterday and the upper and lower limit?
4. What if I subsequently load other company code data into the z table? How can these be loaded as delta by the existing delta? Or must there be another init? can this be done?
5. Technically, if delta is loaded today, and 2 days later, I insert manually into z table a record having the same change date as the 1st delta change date. How does the delta mechanism know about this? I seek clarification that this record will not be known by the delta and will not be picked up and loaded by the next delta infopackage because the change date is incremental and will never pick up and old change date and delta is based on change date selection.
Hope you can enlighten me on the above doubts .
Best regards
Pascal

Hi Pascal,
1. Do we need to Initialize Delta for Generic Delta?
Yes, you need to do init to capture the delta records.for this while designing you have to select Delta check box in data source maintenance screen.
2. If my infopackage used for the init is change date of yesterday, what happens when some days later, I load company code data 2000 into the z table and these data has change dates earlier than the init date?
The change date will be populated in Z table based on system, when you change any record today you won't get yesterday date.anyways in your question as change date is less than last delta run date it won't pick that records.
3. Does init work like this : lets say the data selection in the infopackage used for the init is :
company code = 1000
change date = yesterday.
the 1st delta infopackage will be based on the change date of yesterday and the upper and lower limit?
The best practice is run the init with out any selections, unless when you have requirement that you need to create multiple init's on same data source.
no need to give date selections in info package(already your delta is working on change date).If you need data for a particular company code, give company code other even do not give company code as selection.It will pick all the new or changed data from last delta run.
4. What if I subsequently load other company code data into the z table? How can these be loaded as delta by the existing delta? Or must there be another init? can this be done?
Do not give company code as selection in your delta info package.same delta IP will pick the data for all company codes.
5. Technically, if delta is loaded today, and 2 days later, I insert manually into z table a record having the same change date as the 1st delta change date. How does the delta mechanism know about this? I seek clarification that this record will not be known by the delta and will not be picked up and loaded by the next delta infopackage because the change date is incremental and will never pick up and old change date and delta is based on change date selection.
As i already told we cannot give change date manually, when you save a record this will be populated by system in the table.
Delta settings for generic data source will be maintained in table ROOSGENDLM (here we will have last delta run time stamp on this data source).When you run delta next time, it will pick the data which was stored after delta time stamp.

Venkatesh.

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

Delta for Generic data source.

Hi,
I have created a generic data source for which I have taken the change data as generic delta in CRM4.0. But the problem is delta is not getting initiated. like we are not getting any records in delta. Kindly guide me what else i have to do to get this delta
Thanks
Naveen

Hello Naveen,
What is the delta method you have used, is it Time stamp or ALE Pointer?

Generic delta for master data

Hi All,
I am trying to create a generic delta for master data "equipment" . table in SASP is "EQUI". I am choosing ALE delta . in that I have to provide table name and "changed doc object' . when I give "equi" as table name and "aedat" (changed on ) as "changed doc object' -
it is throwing error.
also when I tried for time satmp /calday delta , the delta doesnot work when changeed are done. don't know why?
Any idea what has to be given in these fields.
Regards,
Dola
Edited by: Dola das on Mar 17, 2010 12:55 PM

Hello,
TCDOB is a table where you need to maintain entries for Generic Detla.
Please goto SE16 : enter table name TCDOB
In the selection Screen Enter Object as EQUI and check the Number Of Entries..
I guess you need to maintain the number of fields on which the change is dependent for Detla ()
I treid creating the same Datasource Using Ale Detla
It worked and saved without errors :
i have the following entries in TCDOB table
OBJECT          TABNAME
EQUI            EQKT
EQUI            EQUI
EQUI            EQUZ
EQUI            FLEET
EQUI            ILOA
Please tell me your count and entries..
so that we can discuss this Further
Also if you find if there are no entries then you can Go to SCDO tcode and maintain entries with respect to change object.
waiting for your feedback

In Generic Delta By selecting 0CALDAY?

hello all
In generic delta,if v select 0calday as a delta type,after selecting this delta type v need to select a field for this delta type,should v need to select Time field only(like Creation date,Last date of creation or something like) or other than Time field like select Matnr,Ername or something like this?
Pl let me know that?

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

Problem in getting Generic Delta records to BW

Hi BW Gurus,
I have got one issues with which I have been struggling a lot for several days . i.e
I am extracting data from R/3 using Generic Extractor (View) from CATSCO and CATSDB. At the time of delta, I tried using Personal No with Time Stamp giving Upper limit as 1800 seconds. I executed Infopackage in BW immediately. But it didn't work out. So plz guide me how I can get Delta Records to BW. Or should I do any necessary factors apart from these in Generic Delta Screen (RSO2).
It is very urgent.
I will be thankful for solving this issue.

Hey I am "Intros" again,,
I am sorry man for giving the wrong T-code mistakenly in my last reply..
To solve the proble...the whole process is same what I told u before..
But... you got to go to T-Code : BD87 , then execute the IDocs manually to bring them in to BW
identify your IDocs which are missing in Monitor screen, then goto BD87 and select those IDocs and click execute... )you can search the IDoc's based on selection conditions)
I hope this will help u...
cheers man..

How to deal with delete record in generic delta of generic datasource

Hi,
Anyone can give me suggestion about the delete record in generic delta of generic data. I need extract data with a generic datasource and hope deleted record in datasource also can be "delete" in next delta extraction. I do a test with generic delta. It seem that the delete record can not be updated in ODS. but updated record can be updated in next delta extraction.
How dose BW generic delta deal with the deleted record with generic delta mechanisim? Or how can I use generic delta mechanisim to realize that BW "delete" the deleted record of source system in ODS with delta extraction?
Thanks in advance!
Billy

Delete is not supported in delta mechanism of generic delta extractor. You will need to add a workaround for that.
- Capture the deleted records somewhere (maybe enhance the txn deleting the record so the key is written to a Z table). Take these records to BW and manipulate the recordmode to affect deletion of corresponding record from ODS.
- If your generic delta is based on FM, and if the 'delete' is captured in change document tables, add the logic to check change document tables whether any records are deleted, and if yes, send those to BW with appropriate recordmode to achieve deletion.

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.

Problem with functioning Generic Delta

Hi Expert !
I Have Created a Generic Delta and has Scheduled the Delta Load By Means of Process Chain In BI Side.
Although it is showing Green(OK) status for the respected Request at PSA(saying No Data Exists FOR PSA) and ODS Lavel but no data is loaded at ODS.
although the data for the same crieria is available in R/3 side.
please share your idea what is reason behind........
Regards
Prakash

Hii I have created Generic Delta On Function Module, also i had checked in RSA3 and it is showing data. Also I have checked the Function Module and the field on which i had created Delta, the Delta Parameters is coming.
I am not able to find what actually the problem is........
Please share your idea if you have any.

Incorrect TimeStamp in Generic Delta (UTC Issue)

Hi,
I have a problem regarding a generic delta extractor. The pointer stored in rsa7 (ROOSGENDLM table) is not UTC but system time. As standard tables store the timestamp using UTC format the delta extractor is not picking up the correct data.
Do you know a solution for this?

Hi,
Thanks for your reply. However I think that unfortunately this solution is not enough
For example:
I execute a delta. My TimeStamp is registered as UTC +2: 20080612160000. (Here I have the error, it should be in UTC)
Now I modify a record in R3 and it is registered with timestamp UTC: 20080612140000.
If I execute a delta it will take all the records higher than 20080612160000. Therefore my modification will never be uploaded.

Generic delta

Hi experts
i have problem in loading generic delta , Generic delta have three parameters
1.Time Stamp
2.Numeric pointer
3.Calender day
and also upperlimit and lower limit
can any one explain me about this parameters and how it works in generic delta
Thanks in in advance

hi,
Yes we have these 3 delta types.
timestamp is used when the requiement of data load is depends on time ie hourly based.
0calday is is used when the requiement of data load is depends on date ie daily based.
Numeric pointer is uesed if u want to load delta based on some fields like sales order,material order.
Lower limit and upper limit used for not to miss the records.

Regarding generic delta.

does any sap bw gurus know the answer to my doubt.
i have created 3 views from mm tables (EBAN,MSEG,MKPF,GLPCA) AND FROM THESE 3 views i have created 3 generic data sorses in r/3 dev server and transported to r/3 quality server and loaded from r/3 qlty server to ods with full update mode in infopackage.
now i want to load delta records for those geeric data sorses, what is the procedure. i have not selected the delta option while creation of data sorses but loaded into ODS with full update.now i want to get delta records, what is the process?
Suppose i have selected generic delta and given some field to get delta records in r/3 dev server, does it effect in r/3 qualty server or do i need to transport same recquest or new recquest for delta from dev to quality server?
this is very very urgent pls. points assigned.

Hi,
ODS may not let you load deltas if there are Full loads already loaded. So either you have to delete them or make them into Full repair using FM RSSM_SET_REPAIR_FULL_FLAG.
This you can decide after talking to users, if they are ok with the data unavailability during the reload, you can delete these data.
Then perform the changes (delta DS) in the DEV and transport it to QUAL.
Then the usual procedure, replicate in BW, perform init load and start deltas.
Hope this helps.
Thanks,
JituK
