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.
Regards,
Gaurav

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 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 .

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:

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 field in generic data source

Hi,
in my data source we contain fields are :
clent,data record number,material,production planning item,sector,G/L account,chart of accounts,recordmode,base unit of measure
from above fields which field was i have to keep in generic delta ?

Ok Ramakrishna,
I could see its a custom data source by looking at the fields you have mentioned..
But you need one date field or time field..on which u want to do delta..
How will you post the data to BW ,ie. based on what field?
Characteristics like Sales Number, Invoice Number,etc which holds unique and increasing value every time are used as Numeric Pointer.
But one problem with this Numeric pointer you cant update the existing records because for every transaction you have to give a Unique numeric pointer value

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?

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

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

More than one field in generic data source

Hi All,
We wanted extract Allocation data for the sales order from R/3 to BW. I am not able to find proper data source for it... there are two datasources..we wanted afs specific datasource
2LIS_11_V_ITM : Sales-Shipping Allocation Item Data
2LIS_11_V_SCL : Sales-Shipping Allocation Schedule Line
But its not reflecting allocated quantity at all...
So we decided to create generic data source.. but there is one problem for some allocation ARUN is initial.. so i cann't use ARUN as delta field... can i use comination of Sales order no,Item and Schedule line number as delta field....
Because in RSO2 i can define only one field as delta specific field....
How to proceed ???
Regards,
Viren.

Hi,
If you decided to use generic data source, make sure that, U'll have to take only
one filed as a delta, I suggest, you take any date field rather than the value fields
it may be created date/change date and so on so forth..

Pattan.

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
