Repeat delta extraction

Hi,
The Finance data is not coming to BW system.We are suppsed to repeat delta extractions.Can anyone tell me how I can proceed?

Hi Prithwish......
A cube will never be in Overwrite mode.........cube is always additive........due to this in some Delta Process.....we need an ODS inbetween.......bcoz in ODS both the Update mode is possible ie Overwritten or Additive......for an example........An after image provides the status after the change, a before image the status before the change with a minus sign. A reverse image sends the
record with a minus sign too, indicating at the same time that it is to be deleted. The data packages are serialized in the process. The delta process controls whether adding or overwriting is allowed. In this case, both adding and overwriting is allowed. This process permits data to be updated in a DataStore object and in an InfoCube.
In case of ODS.............if u r in BI 7.0 then check the update mode in Transformation and if u r in BW 3.X.....then check in Update rule......

Debjani....

Repeat Delta extraction behaviour

Hi experts,
Ive been getting conflicting thoughts on delta extraction behaviour, so I thought Id just ask it out here. Here are two prominent scenarios:
1. Our delta failed on sunday, we execute a repeat delta on monday. It only picks up the sunday failed data, it does not pick up any other new records that came in monday. This is for a generic extractor, R/3 to Cube.
- My understanding is that when we do a repeat delta, it should pick up the failed request + any new records to date. Or does a repeat delta ONLY pick up the failed request and disregards new data? Is the behaviour extractor specific?
2. Our delta failed on sunday, we execute a repeat delta on monday. The request comes up with 0 transferred, we kick of another delta which now picks up everything from the failed request up to the present including new data. This is for 0FI_AR_4.
- Why is it this repeat delta behaviour differs from the first? Is it because this is a FI extractor with inherent behaviour? Instead of picking up the failed request, it picks up 0 records and then a delta is required to pick up all the data.

Hi,
Repeat delta means the data that was collected by the delta queue and not updated to BW vl be updated to the data target., i.e. it picks only the failed request data , not the new ones which are updated in the mean time.
The next delta vl pick up the new records.
It is general to all the extractors except COPA.
For COPA , it updates data based on the time stamp.
Please check the below document for COPA extraction (deltas).

Effect of Change in structure for 0FI_GL_4 on Delta extraction

Hi,
We are upgrading our R3 system from 4.7 to ECC6.0.
In 0FI_GL_4 we have a appended one X field and it was working fine. Now the same filed is available in standard content ( In new Version) Which will cause the structure to become inactive ( We came across this situation in testing phase).. We activated the same by removing the field from Append structure and started pulling records for the same.
1. If I change the extractor and continue with my delta extraction will it work???
2. I have not done any changes to the customer exits written for the old field X...but I didn;t get any dump for the same .. Is ithis k????
Regards,
Rangz

Hi Simon,
Thanks for the confirmation.
In our business process we are extracting data for FI with safety interval 1 day, During upgrade activity ( This will be done on the same Server)
Consider If I Shutdown R3 system today 28th Jan and If I try to extract the data, The FI extractor will get the data till yesterday ,same will applicable even If I do the repeat delta extraction.Is it right???
After upgrade( after changing the 0FI_GL_4 structure, after 2 days of upgrade activity), If I continue with my delta extraction, will it work properly for FI Data sources??? Am I going to get the data records for the transaction that happened on 28th Jan this time????
Or If not any other methods to overcome the same???
Regards,
R@ngzz

Master data Extraction and Repeat delta

hi Expert's I am extracting master data from R/3.These are Delta loads.Now when I started extracting it is pops up message stating earlier request is not correct so repeat must be done.could any one of analyse the problem and give the solution.I also dont know how to do repeat delta.Plz explain with steps.
Thanks in Advance.
vasu.

Hi Vasu,
Goto Manage, Select the Request and make it red(See below how to make it red), then click on the Monitor icon(just side to it). It will take you to Monitor screen.
here select the particular load, on the right side, on the status tab, click on the load and make it red.
Now goback to the infopackage, schedule, it will do repeat delta.If the Problem still persist, then delete the Requet in the Manage screen and schedule again. This should work

Repeat Delta Vs Repair request

Hi Gurus,
What is difference betwenn Repeat Delta and Repair request? May i know the in which scenario we go for these options?
Thanks & Regards,
Prabha.

hai Prabha,
Delta Update
A delta update only requests data which has appeared since the last delta.
Before you can request a delta update, you must first initialize the delta process.
A delta update is only possible for loading from SAP source systems.
If a delta fails (status red in the monitor) or the overall status of the delta request has been set to red manually, the next data request will be performed in repeat mode. A repeat request extracts the incorrect or incompletely loaded data from the failed delta request, along with any new data since the original request. A repeat can only be requested in the dialog. If data from the failed delta request has already been updated to the data targets, delete the data from the data targets affected. If you cannot delete the data from the data targets, duplicate data records may be produced when the repeat request is performed.
The concept of Full repair request is " when we r loading data bydelta update from a data source then it will not allow the Full update from the data source. When we r using this option we can extract the data on repair request then the deltas of the data source is not disturb.
Data will come from the data source only.
repaire request is used to get the missing delta records.
In the info pack menu bar scheduler you will get this option Repair Full Request. generally we use this option for ODS. pls read this OSS note :739863
hope this helps

KP

Repeat Delta is bringing the invalid character back to BI

Hello Gurus
We extract data from CRM using datasource 0CRM_SALES_ACT_I to BI .
Often we are getting invalid character from source system.
When we get the issue rectified in source system (CRM) and re-extract
(repeat delta) we are getting the same invalid character instead of the corrected record.
Our process forbids us to edit the PSA. Request you to please advise.

hi,
in that scenario you can also have a look at the following tables:
RSALLOWEDCHAR in SE16 and also check out program in RSKC_ALLOWED_CHAR_MAINTAIN in SE38
also please have a look on:
173241 : Allowed characters in the BW System
1075403 : Unallowed characters and ALL_CAPITAL
i am not sure if it will help you but what i will recoomend is kindly raise your own OSS note with SAP by System -> Services -> SAP Service and provide your credentials
they will be happy to help you

Delta extraction is not possible at the moment

Hello,
I am trying to run a delta load and am getting the message "Delta extraction is not possible at the moment". This is actually a repeat because i have tried this load multiple times with no success.
The Diagnosis in the error message is:
The delta extraction is not possible at the moment because the status list of the request is locked in the Cube. This can be for a number of reasons:
1. Another extraction is taking place in the target BI.
2. The control parameters of the request in the InfoCube are locked by deletion or compressing processes.
I dont see that any other extraction or a deletion or compression job. I've tried going through each failed job in the monitor and red lighting them but that hasnt helped. Any ideas what to check or how to fix the problem?
Regards,
TMS

Hi,
From what you are describing, there is already some process going on on the infoprovider you are trying to load the data to. Check if a data load is still active/activation is happening, if its a cube then are there aggregates and are they rolling up. You can check the process in SM66 or SM50 and the jobs in SM37.
The process has locked the infoprovider and no delta or for that matter any process can be done until the earlier one finishes. You can take help from the BASIS team to find out what is locking your infoprovider.

Delta Extraction Using Function Module ( Customization )

Dear Experts,
I want a sample code for Delta Extraction using Function Module ( If it is customized already working code very helpful ), I have already created Function Module but Full update is happening. If I give delta update again it is retrieving all records. It is very urgent, if you have please send me to the following mail ID.
[email protected]
Best Regards,
SGK.

Hi SGK,
I've done this for a delta based on a timestamp and it's actually pretty easy. The basic steps are:
1) Create an extract structure in SE11. Make sure the structure has a date or timestamp field in it that you can use for delta. You'll need to include the field twice if you also want to extract it to BW/BI since once it's chosen as the delta field then it will be hidden in the interface.
2) Create the extractor function module in SE37. You can use RSAX_BIW_GET_DATA_SIMPLE as a template. Make sure your logic restricts the data it retrieves according to the selections that are passed in I_T_SELECT, including restrictions on the delta field.
3) Create a generic DataSource in RSO2. Click Extraction by FM then fill in your extract structure and function module. Click Generic Delta and pick your delta field and the appropriate radio button (time stamp or calendar day). If your delta field is a timestamp field then be sure to set the upper and lower safety limits to -86400 and 86400 respectively. This might not be necessary on your version of SAPI but on mine there is a bug where it doesn't translate between system time and UTC (GMT) correctly so this was necessary.
You don't need to program any special delta handling logic in your function module as long as you restrict the data you retrieve based on the delta field (I_T_SELECT). This is because the SAPI takes care of catching the init, delta and repeat requests, translating them to the appropriate delta field values, and then passing them to your function module as if it was a full extraction for a specific date or timestamp range.
Hope this helps!

Pl help me with repeat delta for text info object

Hello during the delta loads delta got failed for some text object, I know how to repeat the request for transction data but not sure how to request the repeat delta for text object like 0material_text.
I mean i am not sure is there way i can go and change the QM status of request to red and then request repeat delta again, so do we follow same procedure for text objects or something else pl suggest.
Pl suggest the steps
due point will be assigned.
Krish

Hi Krish,
With master data delta repeats sometimes you have problems, and you may get a message that Update Mode R is not supported. The only way out of this situation is to do a reinit and load the data again so that you are not missing records. Since this is just master data, the data volume is not going to be too high, and it overwrites so no issues with data either.
See here for reference... Re: Update mode R is not supported by the extraction API
Hope this helps...

Repeat of Repeat delta?

Dear All,
Is it possible to take repeat of repeat delta.
Abhijit

Hi,
Options 1:
Go through the steps to fix the abend,
1. Change the status of the request RED.
2. Execute the InfoPackage again
3. It will ask you whether to continue with new delta or the repeat-delta.
4. Select the REPEAT Delta option.
If the above steps doesn't work then, try the following steps
1. Delete the error request from data target
2. Set the status in monitor to green
3. Execute the Infopackage and Repeat the delta again
Hope it helps you!!!
Option 2:
1.When can we have a Repeat delta,is it with BW or R/3 .
2. We normally do Delta repeat when a Delta request fails for some reason. This will bring the same data again into BW. This repeat delta Info(i.e. the records extracted for a particular delta) are stored in R3 until next successful delta request happens. This is used in repeating the delta request

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.

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.
URGENT
gaurav

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.

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.

Dear KJ,
Thank for your response. I saw the code that you sent, you have used some ztables like ZSC_DELTA_IP, ZSC_SAFETY_DELTA, ZSC_SET_EXT_TIME
What are the fields that you have created in these tables , what is use of these tables, can you send the fields that you have used in these tables.
Thanks & Regards,
