Delta Enabled Generic Data Source

Hi All,
I have created one Delta Enabled Generic Data Source with
Function Module. The Delta field is Date Field. The Data source picks data from R3 to BW.
In RSA3, I executed the Extractor with the Delta Type "C" i.e Delta Initialization ... but it is throwing the error "Errors occured during the extraction". I also checked the Display Log and the error message is "Could not determine BW release of logical system".
Moreover I am not able to see the Delta Attributes in
RSA7. I checked with the other delta enabled generic extractors which uses Views .. is found to be working fine ... and I also able to see the Delta Attributes in RSA7.
Any suggestions?
Bye
Dinesh

Dinesh,
Once you have generated transfer rules in BW for the datasource, delta init can be tried out in RSA3. It iwll not create the delta queue though. Only test the initialization.
To do this, once you have created the transfer rules in BW, specify the logical system name of the BW system in the target system field. After that the extractor can be run in RSA3. It is flagged as read only so delta queue will not get created.
Cheers
Aneesh

Code Page Setting while extracting data using Generic Data Source

Hi,
Can anybody tell me about the Code Page setting used in Generic Data Source in SAP BW 3.5?
I am extracting data from a Master Table using Generic data Source, but the data which is in Ukrane language is getting loaded as "#". Where do we set the Code Page for it?
Regards,
YK.

To continue with earlier question, is there any particular setting for a master data, to load non english data as a text of master data?
I want to load TEXT of a master in Ukraine language. I am extracting this text from the P table of same master (From Description Field). But TEXT is not getting populated whenever it is Ukraine language. English TEXT is populated correctly.
Please share your experiences...
Thanks,
YK.

Problem during extraction using generic data sources

Hi
While performing extraction(master data) using generic data sources I am getting a problem.
while selecting application component, I am unable to find SD to select it.What should I do?
I selected CRM as application component and did the extraction , it is successful.
But what about if we want to select SD? I am guessing it as an installation problem ... Anyone plz help me
Thank you
Deepthi

Hi Deepthi,
Looks like the RFC connection between source system and BW system is broken..
Contact your basis team to check the connection what went wrong.
once the connection is re-established you can gohead ...
Try out this procedure
Type Transaction SM59.
a.) Open the RFC Destinations.
b.) Find your Source System and double click on it.
c.) Technical setting should contain information regarding your source
system
d.) Logon Information should contain source system client and name &
password for you remote logon.
**Suggestion : our remote name for our R/3 was ALEREMOTE. We use
BWREMOTE so that we can monitor without confusion.
e.) Execute your 'Test Connection' & 'Remote Logon'. You connection
should be You should NOT be prompted for a password.
f.) Repeat above to verify RFCs for other systems

Delta for Generic data source.

Hi,
I have created a generic data source for which I have taken the change data as generic delta in CRM4.0. But the problem is delta is not getting initiated. like we are not getting any records in delta. Kindly guide me what else i have to do to get this delta
Thanks
Naveen

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

Error while doing DELTA Extraction (generic data source)

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.

Error in Using Generic Data Source

Hi,
I have created a generic data source which uses a function module and replicated in the same system for testing. Now when I try to create a infopackage and load data into PSA, I am getting a short dump. Please help me out as I am very new to this.

Hi,
in order to get some help you need to provide the information of the short dump as it can have multiple reasons. So please give us a more detailed error description.

To enable delta in generic data source

Hi,
There is a generic datasource created on top of PRPS & RPSCO tables. Currently the extraction mode is 'full update'.
There is no time stamp field available in RPSCO, Please suggest how can I enable delta?

Hi
Make sure at least you have Numeric pointer or time stamp field in your table to make the data source enable.
If you created view on these two tables, then in RSA6 --> open the data source --> goto edit mode.
here you will delta enable check box --> select this check and you can give the field which has to be used for delta.
If you using FM, then you have to write to code in functional module.

Delta enabled generic data source not updating delta

HI,
   Created one Delta enabled generic datasource with the help of ztable .Fill the content of table by manual entries.
   While executin init,records are extracted from R/3 system. After made a change in table entries , it is not captured in RSA3.
   Data source is avaialble in RSA7 after execueting init.
   Delta type== TIME STAMP
   fIELD NAME=zTIME
SAFETY LIMIT=30 SEC
ITS FROM 'NEW STATUS FOR CHANGE RECORDS'
Please help me on this issue..
Regards,
MohammeD

how did you create your data source? - based on view, table for Function Module?
If it is based on a View or table, ideally delta should have worked. If it is not working, please chedk the data type of the field. Make sure that delta field (i.e. ZTIME) is getting updated evertyime you change any record in ztable. While extracting data in RSA3 in delta (D) mode, make sure you also give the target system ID. Also try runnign the delta infopackage in BW if it fetches data.
If nothing works, try creating your data source again.
If it is based on Fuction Module, you will have to include the delta functionality in your code.

Gaurav

Delta enabled generic data source not generating delta

Hi Experts,
I am simply clueless bt where I went wrong.Please have a look and explain.
I first created a z table in r\3 with one field as timestamp.
Then I created a delta enabled datasource for this table, in the delta enabled field I selected Timestamp.
Safety interval left blank.
Delta was chosen as "ADDITIVE DELTA".
After that I saved my data source and replicated the same in BI server.
Then I created an Infopackage to initialize the delta and then one more infopackege was created as delta .
Initialization was successfull.
Now I triggered the delta infopackage to bring delta to PSA
BUT
it does not bring the delta ,rather each time it brings in ALL records to PSA . This is the problem m facing .
PLEASE EXPLAIN ME IF YOU CAUGHT ANY MISTAKE IN THE ABOVE FOLLOWED STEPS.
waiting for reply
Manish Sharma

Hi Teja,
Thanks for your reply, I checked the same .
The initstate field has the value 'X'.
I checked in RSA3 but upon test extraction it says 0 records selected.
Pls investigate more on this.
Manish

Generic Data Source delta is not extracted

Hi,
There is a problem in extracting the delta records using Generic Data Source. Delta records ( New / Modified records ) are not posted in the RSA7.
I'll Explain you the Scenario I have done. Created a generic data source in R/3 using view. In the view there is a field Sales Order No. I have enabled the delta update for this field. In the generic delta i have chosen delta type as Numeric pointer.
Extracted the entire record using full update and after initializing the Delta, it extracts the delta record well ie. it only extracts the sequence of Sale Order No. First I extracted nine records(i.e 10001 to 10009) using full update. again I entered a record in underlying table with sale order no as 10011-10013. It extracts those records into BW system. Then again I made an entry in the table with sales order no 10010. But the record is not extracted. Even though I tried of specifying safety lower limit as -3. Still it not extracting the record(10010).
And what if I posted a value of sale order 10014 with the same. what should I do?? Help on this plz.
--Durai.S

Hi SVS,
Thanks for your reply.
I followed this in my scenario. But I don't understand why it is not extracting? even I specified the safety limit of upper and lower values in the generic delta.
Here the below explanation shows that the delta record can be extracted even if the pointer value is greater than the posted value.
Numeric pointer (last extracted value 10011; Data in underlying table (Max value = 10025) )
Data would be extracted from a min-value of 10010 (lower limit adjusts the last counter 10011 by specified value u2013 1)
max-value of 10020 (after adjustment for upper safety limit u2013 by 5). The current pointer would now indicate 10020 in
RSA7.

Generic data source delta settings

HI
i have to create delta for Generic data source based on 2 fields like "created on" and "changed on" fields.
how to set this
try avoid numeric point & Whit out using function module
and what is the safety interwell (Please use simple words)

Hai Sudha,
Safety inteval is nothing but for ex you have updated your data from R/3 to bw at 11 am If client want the data in between 11.1min to 11.4min the records which are going to present in between the 1 min to 4 min that records only can updated if and ony if your data source is going to make as an generic delta.
bye.

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.

Generic Data Source with Function Module data mismatch in BI

Hi All,
I'm using Generic Data Source with Function Module, When I execute the Function Module (Which I have Created), I'm getting 16000 records and when run extractor(in RSA3) im getting different no.of records(infact they are more no.).
when I run the InfoPackage in BI im Getting more no. of records than what i got executing the function module..
and single record is divided into 2 records in BI side(not all the records), how can it be possible???
is there anything Im missing to explain you my issue???
if understood please help me out.
Thanks n Regards,
ravi.

the datasource frame work starts the function module several times.
1. the initialization
2. the serval times, until you "raise no_more_data".
check you coding: have you refreshed necessary internal tables.
