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

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 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 .

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.

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

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

How to set the delta for existing generic data source

Hi BW Guru's
I have a problem,actually i have a exsting generic data source"ZFRBHRCHY". Master data Object ZFRBHRCHY is getting laoded from all some R/3 Clusters on a Daily Basis. It is full load and takes 4 to 5 Hours, but number of added records(2000) are very less,while total records are more(40Lks).For avoiding this larger load time every day,i want to implement delta extraction for this.
How to implement this,(i want steps for this) .
Thanks in advance,
Regards
reddy

yeas agree with sanakar,
this field which shankar is talking about must be entry date (if u delta timestamp is date, u will also have to mention this table field name in definition of delta), this means that this field will catch last change to the record, so that it will be delta enabled based on the latest change date. This is very important becuase if u use date like posting date to the delta then back dated posting will not captured in to the delta, as delta for this back date is already been done.
Hope u understand this.

Currency field in Generic Data Source

Hi All,
I have a case here, where i have few Amount field in my Generic Extractor which is based on a table ZXXX.
Now the key figures have 0currency appended in theie currency tab which is coming from table ZYYY, now while saving the data source is giving error that the extract structure is not proper, reason being the base table has no currency field and the kf's need to have one currency field to assign to it which is coming from some other table.
One sloution is create an FM based extractor, but we dont want that.
Can any one suggest any work around without any FM or View??
Thanks,
Neha.

if your table have currency field with different reference table and field mean
you have to create view
Diagnosis
You tried to generate an extract structure with the template structure eg:XXXX(table). This operation failed, because the template structure quantity fields or currency fields, for example, field XXXX(fileld) refer to a different table.
Procedure
Use the template structure to create a view or DDIC structure that does not contain the inadmissable fields.
1.Create the view
2.Add the currency field and currecy key field also
3.Create the generic data source in RSO2

Delta settings in Generic data source

Hi experts,
I have created a generic datasource based on infoset query i,e the table KONV (Cluster table).
I maintained the delta settings in rso2 as follows:
Delta specific field : KNUMV Doc condition number.
Calendar day.
Safety interval upper limit: 1 Calendar days.
New status for changed records.
Are the above settings correct ?

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.

Urgent: Add field in generic data source

Hi,
Could anyone please help me out in resolving the issue to add field from different table in generic datasource.
How can I add it in R/3 data source when a function module was created in ABAP to generate fields from PLPO table?
Whatz the changes has to be done at BW side to map the added field?
<u>Requirement</u>
1) Need one more field in the extractor. Field name is PLAS-LOEKZ. Initially client wanted me to add PLPO-LOEKZ which I added, now he needs the same fields from both the table (PLAS and PLPO).
2)The name of the extractor/structure is ZBW_ROUTINGS_OPERATION
3)Now, we need to add this field (LOEKZ from PLAS) in the function module as well. FM name is: Z_BW_ROUTE_OPERATION_EXTRACTOR. This will be in a SELECT query. We need to add this field in the SELECT statement.
Testing will be done in following steps
1)     Go to Transaction RSA3.
2)     Enter the data source Z_BW_OPERATION_ATTR(not sure about the name though, but it should end with OPERATION_ATTR)
3)     Enter the following details:
EXTTY I
PLNNR 50000032
PLNTY N
4)     Now execute (F8) the transaction.
5)     Click on Display List
6)     In the output, we should be able to see these 2 columns(PLAS-LOEKZ) and (PLPO-LOEKZ)
Please send your valuable suggestions to resolve the issue ASAP as its damn urgent.

Hi,
Here is an overview of the solution -
Use T.Code SE11> ZBW_ROUTINGS_OPERATION. Add your new field (PLAS-LOEKZ) to this table, check, save, activate. Edit your function module, SE37> Z_BW_ROUTE_OPERATION_EXTRACTOR and add your code to look up the correct value of this field LOEKZ from the table PLAS, check, save, activate. (Note that SAP provides a sample function module you can use as a template and customize for your requirements. This sample function module is RSAX_BIW_GET_DATA_SIMPLE.)
Your Generic DataSource Z_BW_OPERATION_ATTR is already created, you dont have to change any settings here. Just regenerate it in RSO2. Now test the extraction for the DataSource in RSA3.
Hope this helps
