JDBC-- PI7.0-- SAPBI with Proxy

Question

Hi Experts,
I have a requirement like this : JDBC(Sql Server)>PI7.0>SAPBI. 
I need a suggestions from the above requirement. For this requirement I am planning to use sender as a JDBC Adapter and Reciver as Proxy. I have some questions on this requirement.
1) I need to extract data with more than 15 tables of Sql server data base. Is it possible to extract all data at a time, If yes plase give me some tips.
2) How to combined all 10 extracted tables data into as a Proxy. Please provide some inputs. or it better each table as a one XML file like this....
Lastly one more question is, what is best process for the above requirement either Proxy or IDOc's.
Thanks in advance.
Regards,
Chandra.

Hi Chandra,
In addition to the above responses you can follow the approach as:
1. Discuss with your DB team and find out what is the average number of records to be selected from each table on each run of the interface.
2a. If the number of records are large then its better to go for separate interface for separate tables.
2b. If the number of records are limited say 15-20 then you can work either with a single staging table or a stored procecdure after discussing with the DB team what they can agree to.
3a. In case of a single staging table:
i. Create a data type similar to the staging table fields.
ii. Generate a proxy accordingly.

3b. In case of stored procedure
i. Ask the DB team to include a single Select querry with in the Stored Procedure, and also to include a update querry to update the read records once called by Stored Procedure/ DELETE the read records.
ii. In the JDBC sender adapter in the field Query SQL Statement write the querry as as: EXEC "Stored Procedure Name" ("Parameters if any").
iii. In this case your Sender Data type structure should be same as the structure being called by the Select query with in the stored proc. or in other words the sequence followed in the Select query should be same in the sender DT.
iv. Generate a proxy accordingly.

Note: Proxy is always better in this case upon IDOC. If asked by business or BI team you can as well go with RFC keeping in consideration the load/no. of records. In case of bigger messages Proxy is always better being a adapter less communication.
Hope this helps you.
