Extracting updated data from SAP R/3 to BOBJ DS

Question

Hi all,
I have a doubt reg extracting updated data from SAP to BOBJ DS. For example i am extracting 50000 records from SAP table to BOBJ DS say its taking half an hour, after extracting data 10 more records have added in the same table. Do we need extract the whole record again or do we have some other way to extract only those 10 records from table.
Please help me.  I have searched in forums but cudnt find the exact solution fyi.
Thanks,
Guna

Answer 1

Apart from stepd 1,2, you need to create a Target Data store and a table to load your MARA data.
3. Now the MARA data will be available in data store(DS_ERP), say table name as BO_MARA
  Why do you want to change the table name? Are you planning to stage the data anywhere?
4. Create a dataflow source as BO_MARA, query transform and destination as a table
Data transport object is required if you are using R/3 Data Flow.
This would suffice just for a full load, if all your transformations can be incorporated inside the Query transform.
5. Do Transformation.
6. Transformed data will be available in target table.
Only after executing the job that the transformed "data" will be available in the target.
The above part mentions only about a Source, Query transform, Source Data Store and table.
Apart from these
You would require a Script object to write the condition, to SELECT the MAX timestamps. You would require Variables to be created in your job to redirect your job path and to restrict the data extracted.
Use your DataFlow in a Conditional object. If load type is first, in the then part use the dataflow which you might have already designed. Else part will have a replicated Data Flow with the above mentioned WHERE condtion in Query transform.
Suggest you to refer Desiger document and DI supplement for SAP as well. Inform if you are stuck.
