Delta upload for generic data sources.

Hai All,
I tried as per SAP online document , but still i am not getting the result i.e delta upload from the BW side. Here i explained everything what i did.
In R/3
1. I have created a table with 3 fields SNO, SNAME, DOB
2. Then i created some entries in that table.
3. With Tr Code RSO2 i created one data source. Here i took Master Attribute Datasource
4. In generic delta i took the Generic field as DOB. and Time stamp and upper limit 10 sec.
In BW side
1. I have replicated the data sources under application compone in which i have creatred in R/3..
2. Then i activated that data source and created infopackage for that.
3. in the selection i have specified 01.01.1900 to 01.01.9999
4. First i made Full Update then i get all the records from R/3.
5. In R/3 i have created 2 more entries.
6. In Infopackage UPDATE Tab i have selected the Initilize Delta Process ( Initialization with Data Transfer).
For this i am getting the error message as follows.
Error message from the source system
Diagnosis
An error occurred in the source system.
System Response
Caller 09 contains an error message.
Further analysis:
The error occurred in Extractor .
Refer to the error message.
Procedure
How you remove the error depends on the error message.
Note
If the source system is a Client Workstation, then it is possible that the file that you wanted to load was being edited at the time of the data request. Make sure that the file is in the specified directory, that it is not being processed at the moment, and restart the request.
Here i closed the all things in R/3 as per the note mentioned above. Still it is giving the error message.
If i select the Intilization Delta Process( Intilization with out Data Transfer) then i am getting the option Delta Update . I selected this Delta update and scheduled but no data is coming.
Please help.
Regards
Prashanth K

Hai Sachin,
I am getting the problem at PSA only. Actually that is connected to ODS Object only. Until unless we don't get the delta data into PSA we can't proceed futher. So please help. I am working on NW 2004S.

Delta Option for Generic Data Source

Hi ,
My requirement is Delta Option for Generic Data Source. This Data Source is getting Extracted from Function Module.
For this requirement I have followed below steps.
1) Added the Field (On which Delta gets enabled) to the extract structure by using Append Structure
2) Enabled Delta On this Filed.
3) If I try to save the Data Source, I have gone to a screen where I am able to see 4 coloumns
a) Selection
b) Hide Field
c) Inversion
d) Filed Only known in User Exit.
By default Hide Field and Filed Only known in User Exit check boxes have been checked.
Would you please tell what is the use of Filled Only known in User Exit check biox.
As My data source is getting the data buy using the Function Module, Shall I uncheck this Check Box.
Thanks and Regards,
K.Krishna Chaitanya.

Hi Krishna,
The "FIELD" should be checked if we write any enhancement in CMOD, so that system can identify that this particular field has enhancement written to it,
But even in real time systems i usually find that even though we check the "FIELD" or not , there is no effect .
So Checking "FIELD" or not will not impose any isses .

Time Stamp Delta field for Generic Data Source

Hi Experts,
I have a requirement to create a Generic Data Source based on view. This view on PA0006 and PA0105 tables.
Will you please suggest me which field i have to take as delta field.
Thanks In Advance.

Also, make sure that whenever a new record is created in those tables, field AEDTM is getting updated with system date else you will miss new records in delta unless there is a change in those newly created records.

Delta field for generic data source based on view EKBE

Hello,
I am creating a generic datasource based on table EKBE. Can anyone please tell me what field should I use for delta. Is it BUDAT(Posting Date in the Document) or CPUDT(Day On Which Accounting Document Was Entered).
Thanks for the help.
Praveen

Hello Ajeet Singh,
Thank you very much for the reply.
I will go ahead with CPUDT.
BUDAT is the date which can be changed. I can change the date in system and chances are it will not pick in delta.
CPUDT is the date on which document was created/changed.
Thanks,
Praveen

Delta On CALDAY Filed for Generic Data Source

Hi,
I have enabled delta option on CALDAY Field for Generic Data Source.
I thought of giving Safety Interval for Upper Limit as 1 and Safety Interval for Upper Limit as ZERO.Would you please advise me on this, This fetches all delta data?.
Would you please advise me on this.
Thanks and Regards,
K.Krishna Chaitanya.

Hi Krishna,
If your delta enabled field is Date then try this,
Safety Interval Upper Limit Calend. Days
Safety Interval Lower Limit 1 Calend. Days
Then test your delta, will get good result.
I created 4 GDS with this safety interval and working fine for me.

Hello Naveen,
What is the delta method you have used, is it Time stamp or ALE Pointer?
See this SAP Note 539547 Generic delta with date does not work
Please see these docs as well

Delta method preferable for generic data source

Hi All,
I'm working on APOBW ,i need to pull primary sale data into apobw .So ABAP er created a program to pick the data from tables vbrp,vbrk,knvv,mara,marc,t179 and populating into a transparent table.I have created a generic data source using that ztable and then loading data to infocube in APOBW.I need to pull data daily twice.I have fields data and time in the Z table.
Please suggest me how to pull the delta data and let me know if DSO is needed in between before loading to Infocube.
Thanks.

Hi,
For Enabling Delta, while creating the Generic Datasource you have an option of Enabling it to be Delta capable. Select Generic delta at the top and then you would see 3 options of how you want to get your delta records.
It is based on
1) Timestamp
2) Numeric Pointer
3) Calendar Day
Depending what you have in your Table, you can select on what your delta would be based.

How to enable delta in a generic Data Source

Hi,
   I am developing a Generic Data Source (Z) based on a view.
   How can i enable it to delta capable...
   What is the concept of Calanderday......timestamp....pointer
   How can i make a decesion (what factors do i need to consider) to go for Calanderday......timestamp....pointer
Please provide me detail steps & description on this as this is my first data source
Thanks

1. Time stamp - The field is a DEC15 field which always contains the time stamp of the last change to a record in the local time format.
2. Calendar day - The field is a DATS8 field which always contains the day of the last change.
3. Numerical pointer - The field contains another numerical pointer that appears with each new record

Issue with Safety Upper limit for CALDAY Field for Generic Data Source

Hi,
I have given Upper limit as 1 for Calday field of one of the Generic Data Sources.
I have got a doubt here.If today's load got failed and I will rerun the load next day.So Will that new run captures all 2 days records.
Can any one advise me on this.
Regards,
K.Krishna.

Hi,
A one-day upper safety interval determines that an extraction run today, only fetches records up to yesterday (if the pointer has the day before yesterday date, the extraction comprises from the day before yesterday to yesterday). This is meant to avoid missing records that were about to be persisted in the database when the delta extraction is running but whose date was determined in memory before the delta started.
If pointer has today date value and you want to load data from today and yesterday, you should use a lower safety interval. Take into account that this could reload data previously extracted. Therefore, only InfoProviders with overwritting features (DataStores or InfoObject master data) should be used as targets of this extractions.
You can find further details at:
http://help.sap.com/saphelp_nw04/helpdata/en/37/4f3ca8b672a34082ab3085d3c22145/content.htm

Delta Issue in Generic data source

HI all ,
    I have a HR generic data source .which extracts only two records ffrom the source for so many days during delta.
   I checked in RSA3 .It shows 16000 records nearly. I did init without data transfer and then delta,still it picks onlys same 2 records .
   Delta setting in RSO2 is Numeric pointer with new status for changed records with field name as"cheque number"
   In BWdatasourceExtraction tab--Deltaprocess is AIE After Image by extractor.Iam not able to choose any other delta process type as it is built from R/3 .I think because of this process type.
anybody faced the same problem .. I tried many ways.. please guide me how to solve. this issue.

HI Prashanth,
                    I checked RSA7 now and I found the problem .In RSA7 the pointer for cheque number is 991749. The delta record created has cheque number 005409 which is lesser than the pointer ,thats why the record is not picking i guess.
       now ,If this is the case ,How can I give delta field.The generic datasource is built on only one table PAYR ,and having cheque number and other fields as keys in the table PAYR.Date is not a key in the table. Please help how to proceed
Thanks

Update types in infopackage for generic data source

Hi,
Suppose if we create a generic data source,then
1) What are update types availbale in infopackage for tha generic t data source?
2) Is there any link between,the selection on the
i) type delta type select
ii) the field selected i.e like timestamp,cal month,numeric pointer.
3)do we have delaa option at info package level?
I think you understood my doubts.
Regards
Naresh.

hi siva raju,
yes our's is bi 7.0.but there are two DTP with the same optoion of DELTA.It pull the data from ds to info cube.
one more thing,how are the delta records picked from the r/3 to bw?its through Infopackage Am i right?
If possible please tell me the entire flow of data goes for a generic data source.
i.e
how to load data?
how to set delta?
how do we load deltas to bw.?

Delta Activation for a data source

Hi All,
Thank You Very much for reading this query.
In Source System, I have enabled Delta on Calday field for a generic data source by clicking on Generic Delta Button.
For this data Source, extraction is from data base table.
Now Do I need to write any function module for this data source, as I have enabled Delta.
Would you please help me on this.
Thanks and Regards,
K.Krishna Chaitanya.

Delete duplicate request is a process chain variant, which will allow you to set the duplicate request deletion options. You need to explore those options.
Now say you have a routine in the DTPs.
DTP1 = Current Month
DTP2 = Prevoius Month
In the month of July,
DTP1 = 07/2009
DTP2 = 06/2009
On daily basis DTP1 will load data for July and DTP2 will load data for June. Now delete duplicate request will delete the previous requests loaded by each of them for the same month. Meaning delete duplicate request for DTP1, will delete the request loaded for 07/2009 and DTP2 will delete the duplicate request for 06/2009.
Now when you will be in Aug, the routine will change the selection criteria
DTP1 = 08/2009
DTP2 = 07/2009, so now DTP2 will delete teh duplicate request for 07/2009 and load the new data. Now the data changed for 06/2009 is not possible to load as you have only 2 DTPs.
For safer side, you can create 3 DTPs to take care of the last 3 months, but first test the logic for two DTPs and then go further for the third DTP.

FUNCTION MODULE CREATION FOR GENERIC DATA SOURCE

Hi BI gurus,
I am creating function module for generic datasource. For that I followed below mentioned steps
Steps
1.     Created s structure with the fields that needed.
2. Created FM by copying the standard Function module
" RSAX_BIW_GET_DATA_SIMPLE " and Give a New name starting With
Y or Z .
3. IN SE37 ->Your Function module name -> Change, In table tab given structure
name by deleting the associated type given in E_T_DATA .
And inserted the required code given below
      PROGRAM 'ZHU_BALANCE'.
*& Report ZHU_BALANCE
TABLES: VEKP, VEPO.
DATA: BEGIN OF T_DISPLAY,
      DATE   LIKE SY-DATUM,
      EXIDV LIKE VEKP-EXIDV,
      LGORT LIKE VEPO-LGORT,
      WERKS LIKE VEKP-WERKS,
      END OF T_DISPLAY.
DATA: ITAB_DISPLAY LIKE TABLE OF T_DISPLAY.
DATA: WA_ITAB_DISPLAY LIKE LINE OF ITAB_DISPLAY.
SELECT VEKPEXIDV VEPOLGORT VEPO~WERKS
       INTO CORRESPONDING FIELDS OF TABLE ITAB_DISPLAY
       FROM VEKP AS VEKP INNER JOIN VEPO AS VEPO
         ON VEKPVENUM = VEPOVENUM
         AND VEKPWERKS = VEPOWERKS
       WHERE VEKP~VSTEL = SPACE
         AND VEKP~VEGR1 = '401'
         AND VEKP~VPOBJ = '12'
         AND VEKP~STATUS = '0020'
         AND VEPO~VEPOS = '000001'.
LOOP AT ITAB_DISPLAY INTO WA_ITAB_DISPLAY.
WA_ITAB_DISPLAY-DATE = SY-DATUM.
MODIFY ITAB_DISPLAY FROM WA_ITAB_DISPLAY TRANSPORTING DATE.
ENDLOOP.

ENDLOOP.
While checking the function module its populating the syntax error as
THE TYPE SRSC_S_IF_SIMPLE IS UNKOWN. (Though this is commented in program)
So pls suggest

hi indira,
thanx for ur reply we have created the funcion module successfuly it is also showing the output correct. But when we put that function module in the generic data source and try to extract data in RSA3 it shows the correct output of function module but with the msg ' 0 entries found in customer enhancement' and therfore zero records in the display list.
is there any correction or steps to be followed in data extraction
pls suggest
