Problem while delta extraction

Dear Experts,
I am facing a poblem while delta extraction for AR ODS. When I check the status of delta extraction it shows green and records transferred as well but when i check into BW side I find some records missing. When I faced this problem for first time I did the init load again after which all records came into BW side but subsequently again when some changes were made in R/3 side and delta was uploaded, again the same records were found missing.
If anyone has any idea why this is happening please guide me as to how to go about it. Also I have given no filter conditions in data selection.
Thanks in advance. Will assign points happily for any kind of assistance.
regards
akshat

Hi,
the standard delta extraction is not sensitive to program in the R/3 side that write directly into tables. For my experience, this is the only reason when the delta does not work.
So, check with the R/3 people, if they are input account document by write directly into BSIS or BSAS.

Problems with Delta Extraction for 0CRM_OPPT_H (no data found)

Hi,
I've some problems with the Delta Extraction of the Infosource 0crm_oppt_h (CRM Opportunities Header). After initialization I get no delta data from the CRM system.
What I already did:
Activated 0crm_oppt_h Data Source (checked functionality with rsa3)
Started Info Package (Init) on BW side (worked fine)
Checked the status of the Data Source on the CRM system using BWA7 ("initial upload" is unmarked; "delta active" is marked and what makes me worry is that the column "Queue exists" in <i>unmarked</i>...)
If I change anything (like Phase, Expected Sales Vol.) in the opportunity, the Delta Extraction get no changes.
Could You help me out, please?
Best regards,
Markus Svec

hi Markus,
try to check oss note 788172
Release Status Released for Customer

Priority Correction with high priority
Category Program error
Symptom
No data exists in delta extraction from the CRM server to the BW system for business transactions, if parallel processing is applied as per note 639072. But Data is extracted if parallel processing is switched off.ie. when BWA_NUMBER_OFF_PROCESSES is set to 1,there is data during delta. This applies to the following DataSources:
0BBP_TD_CONTR_1
0CRM_COMPLAINTS_I
0CRM_LEAD_ATTR
0CRM_LEAD_H
0CRM_LEAD_I
0CRM_OPPT_ATTR

0CRM_SRV_CODES
0 CRM_SRV_CONFIRM_H
0CRM_SRV_CONFIRM_I
0CRM_SRV_CONTRACT_H
0CRM_SRV_PROCESS_H
0CRM_SRV_PROCESS_I
Other terms
DataSources, BWA, initial extraction, delta init, parallel processing, no data in delta.
Reason and Prerequisites
There is an update on the generated delta table which causes data corruption in running delta initializations as the changed delta sets will be deleted with every further update on documents. An open cursor statement is there without fetch data in SMOX3_GET_DATA.
Solution
The problem is solved with the attached corrections.After applying the corrections a new initialization of the affected datasources is necessary.

Help! Problems with delta extraction

Hi All,
We've been trying to run a delta load of material master data and because there are so many change records (2.6m) it has been failing on memory errors. We have now run full load and it completed successfully. Ran delta again expecting that it would pull 0 records but it is still trying to pull all 2.6m records. Ran init w/o data. Ran delta again - still pulling 2.6m and failing.
Since we have successfully run full load, is it okay to delete the records from BDCP/BDCPS??
Other suggestions??

If you are not using it for other uses (eg. ALE with change pointers), it would be safe to remove the change pointers. You can use BD22 to delete them.

Problem understanding delta extraction BI Content DS 0FI_GL_6

Hi SAP experts,
I am trying to understand delta loads for 0FIGL_C01 with DataSource 0FI_GL_6. This DataSource uses delta procedure AIE. I have got two literature sources telling me, that the delta queue of the source system is populated even if the delta is a pulled delta like in this case (http://help.sap.com/bp_biv270/documentation/FunctionInDetail_DE.pdf page 23 and SAP BI lecture notes). However, http://help.sap.com/saphelp_nw04/helpdata/en/41/4b73415fb9157de10000000a155106/content.htm claims that deltas from DS 0FI_GL_6 are transferred directly to SAP BI passing by the delta queue.
Looking at transaction RSA7 in the source system, it tells me that there is a delta queue for 0FI_GL_6 with 1 LUW. However if I take a look on this LUW data is showed only for "delta repeat" but not for delta upload. I haven't done any delta repeat.
Can somebody tell me if DataSource 0FI_GL_6 uses the delta queue, which of the contradictory literature is correct and why I can't see any data there for delta uploads??
Thank you very much in advance
Martin

Hi Boris
Have you made an initialisation?

Generic Delta extraction by Function module issue

Hello Experts,
Please help !!!
I have problem for delta extraction by Function module. For the full load, I wrote function module based on RSAX_BIW_GET_DATA_SIMPLE. It works fine.
But I would like to have the delta load enabled. Therefore, I modified the datasource, add a delta specific field u2018ztimestampu2019, which type is calendar day.
Then I create a function module based on template u2018RSAX_BIW_GET_DATAu2019, as this support the upload mode. But when I test this datasource in RSA3, no matter itu2019s full load or initial delta load, it always send me an error, u201CErrors occurred during the extractionu201D.
I had some debug, and found that there is no value for i_isource when my function module is called. Therefore it raised the exception.
But I do not have the chance to debug my code for the delta logic, can somebody help to check?
I also check the entries in ROOSOURCE,
For my datasource ZTRNREC_FM_DELTA, The DELTA value is u2018AIEu2019, and extraction method is u2018F2u2019, should I change them to DELTA= u2018Du2019 and extraction method to u2018F1u2019? Where to change?

parameter I_PRIVATE_MODE (not supplied by BIW !) to distinguish
between BIW calls (I_PRIVATE_MODE = SPACE) and other calls
(I_PRIVATE_MODE = X).
If the message handling has to be different as well, define Your own
messaging macro which interprets parameter I_PRIVATE_MODE. When
called by BIW, it should use the LOG_WRITE macro, otherwise do what

I found some similar issue in this forum by link
Generic Extractor Delta Function Module code, but still I could not get clear answer.
Can you please help me:
1)     why there is no value for i_source , how to fix it?
2)     For the delta logic for ztimestemp, is it correct?
3)     Need I modify the entries in ROOSOURCE ?
Thanks a lot !!!

I think it already includes the important statements you suggested.
I test this FM in RSA3, for the Full load mode, it works fine. Also if I checked the debug mode in execution , it will stop in the code and let me debug.
But when I choose other mode, like 'initializion of the delta transfer' or simulation of initial delta, I always get error 'error occurs during the extraction' .. even I choose debug mode, but it could not enter the code for debug..
Till now I did not see any parameter or value for the upload mode..
Another questions is that, in RSO2, I define Ztimestamp as my delta field.. But , can I add other field as selection condition in the datasource definition, and has its range table in this function module ?
Should I change the entries in ROOSOURCE for this datasource ??
Please let me know your feedback, do you have some concret example for generic delta extraction ?
Thanks a lot !

0FI_GL_6 delta extraction

Hello Guys,
i have a problem with delta extraction for datasource 0FI_GL_6. With full extraction we have no problem but delta doesn't work.
Seems the problem is in table BWFI_AEDA2, in this table we should have all changed document (probably registered by the change pointer) with table key GLT0 but we have no entry with this key and we dont' know Why
Do you know if we have to activate something? , why we have no entry in table BWFI_AEDA2 with GLT0 key ?
Thanks in advance
Boris

Hi Boris
Have you made an initialisation?

Error while doing DELTA Extraction

Hi BW Experts,
In my R/3, I have a generic data source ZBUT_VW.
It receives data from a View which is created based on couple tables.
When I do full load to the corresponding ODS, it is successful.
But after that I delete the ODS and created CUBE with DELTA
I have Initialized delta.
When I do DELTA extraction, it fails.
The error
The ALE inbox of the SAP BW is identical to the ALE outbox of the source system
and/or
the maximum wait time for this request has not yet run out
and/or
the batch job in the source system has not yet ended.
I delete the initialization load and trying to do DELTA extraction again and it Fails With the same error
Please let me know how can I resolve this problem.

I dont think it is possible to have to additive delta with creation date.
Try a full load to cube to check if the extractor is working.

Problems While Extracting Hours From Date Field

Hi Guys,
Hope you are doing well.
I am facing some problems while extracting hours from date field. Below is an example of my orders table:-
select * from orders;
Order_NO     Arrival Time               Product Name
1          20-NOV-10 10:10:00 AM          Desktop
2          21-NOV-10 17:26:34 PM          Laptop
3          22-JAN-11 08:10:00 AM          Printer
Earlier there was a requirement that daily how many orders are taking place in the order's table, In that I used to write a query
arrival_time>=trunc((sysdate-1),'DD')
and arrival_time<trunc((sysdate),'DD')
The above query gives me yesterday how many orders have been taken place.
Now I have new requirement to generate a report on every 4 hours how many orders will take place. For an example if current time is 8.00 AM IST then the query should fetch from 4.00 AM till 8 AM how many orders taken place. The report will run next at 12.00 PM IST which will give me order took place from 8.00 AM till 12.00 PM.
The report will run at every 4 hours a day and generate report of orders taken place of last 4 hours. I have a scheduler which will run this query every hours, but how to make the query understand to fetch order details which arrived last 4 hours. I am not able to achieve this using trunc.
Can you please assist me how to make this happen. I have checked "Extract" also but I am not satisfied.
Please help.
Thanks In Advance
Arijit

you may try something like
with testdata as (
select sysdate - level/24 t from dual
connect by level <11
select
to_char(sysdate, 'DD-MM-YYYY HH24:MI:SS') s
, to_char(t, 'DD-MM-YYYY HH24:MI:SS') t from testdata
where
t >= trunc(sysdate, 'HH') - numtodsinterval(4, 'HOUR')
S     T
19-06-2012 16:08:21     19-06-2012 15:08:21
19-06-2012 16:08:21     19-06-2012 14:08:21
19-06-2012 16:08:21     19-06-2012 13:08:21
19-06-2012 16:08:21     19-06-2012 12:08:21trunc ( ,'HH') truncates the minutes and seconds from the date.
Extract hour works only on timestamps

A problem with 1CL_OLIS002 and 1CL_OMAT001 extractors - delta extraction

Hi
I have a problem with 1CL_OLIS002 and 1CL_OMAT001 extractors - delta extraction.
Interrelated extractors: 2LIS_11_VAITM and ZMATBATCH_Attr work well.
For 1CL's extractors I see current data in RSA3 but I don't see LUWs in RSA7.
Extractors send 0 records to BW.
There is no entry in "BIREQU* " job logs like this:
"Call customer enhancement BW_BTE_CALL_BW204010_E (BTE) with xxx records".
which I find in job logs when all worked well.
We had some problems with R3. I had to restart job "LIS-BW-VB-APPLICATION_13*".
May be it has influence on these extractors?
Any suggestions about how to resolve the problem?
Regards
PWnuk

Hi
Can you please share the solution of this problem with me,I am also facing same issue of Delta not working but full load is working in 1CL_OBI_001?

Problem while selecting BELNR from BSEG

Hi Experts,
I have a report performance problem while fetching BELNR from BSEG table.
I have to print latest BELNR from BSEG where BUZID = M but at the time of execution of report, It is taking too much time (More that hour and sometimes it gets hanged).
I have also gone through the comments provided by experts for previous problems asked in this forum e.g. BSEG is a cluster table that is why data retrieval takes long time etc.
Can any one has any other idea or suggestion or any other way to solve this problem
Regards,
Neeraj

Hi,
1) Try to create an index on BUZID field
2) Don't use SELECT/ENDSELECT statement. Instead of that extract all the concerned entries from BSEG into an internal table :
select belnr from bseg appending table itab where buzid = 'M'.
then do this :
sort itab by belnr.
describe itab lines n.
read table itab index n.
Please reward if helpful.
Regards,
Nicolas.

Business Partner Items (0FC_BP_ITEMS) delta extraction help

Has anybody used 0FC_BP_ITEMS extractor? The documentation says that it supports delta, but it needs to be enabled.
I did enable delta extraction in IMG as SAP help site suggested. However, the documentation also says that before running delta, I need to update/initialize it in tcode FPOP. I go to that tcode, but I can hardly understand what to do in that tcode and there is no help or documentation I can find on how to initialize that delta extraction for 0FC_BP_ITEMS in OLTP system.
anybody came across any help document on FPOP tcode?
Thanks

Have you found a solution to the problems you were facing? is there any documentation you have regarding the BP Items extractor.

No purchasing date in delta extraction (2LIS_02_ITM, 2LIS_02_SCL)

Hi.
We have been experiencing some issues with delta extraction of purchasing data, using 2LIS_02_ITM and 2LIS_02_ITM.
In particular, the posting date's field (BUDAT) is not always filled: for example, I noticed that when users set the final delivery flag even if the purchase delivered quantity does not correspond to the whole order's quantity or the flag has been set later than the change of the delivery date, the field (BUDAT) in the delta queue is not filled.
By this way, the field may be overwritten: however, we need to keep the posting date value.
I am wondering whether I am correct and, in this case, it is possible to keep that value: however, it seems that the only way is to use a full extraction of data.
Thanks a lot

Roberto Negro,
While filling setup table by using T-code OLI3BW (Purchasing) it is taking very long time.
Please let me is there any way to rerduce this time.
We are at BW 7.3 version.

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
