Fundamnental question on jdbc sender adapter

Question

Hi ,
I have a scneario like
DB System „³ JDBC Adapter „³ XI  -„³ RFC Adapter „³ SAP R/3 --„³ True „³ response thru same RFC adapter „³ XI BPM will call JDBC Apdapter with Update statement
                                                                                False „³ response thru same RFC Adapter „³ XI BPM will call File adapter with Append
now when i use send jdbc adapter , i wld need to have a status flag in my database which would be update when ever data is transmitted sucessfully else the same data would always be picked up .
i want to know do i need to create a reciever jdbc adapater too for this . because when ever i use sender jdbc adapter and this must be a very common situation . that i have to update the table so that the rows are not picked up again . jdbc senser  has an update statement . writtng an updtae query will it not solve my problem.

Hi Amit,
A JDBC sender adapter has 2 essential fields,
1. SQL Statement
2. Update Statement
Your SQL statement will contain your SELECT statement and once your SQL statement is executed, UPDATE statement is executed. This is done so that records that have been selected by the SQL statement should not be selected again as the JDBC sender adapter will poll over the database for every poll interval.
If you want to SELECT something from your Database, then you will have to go for a JDBC sender adapter.
But, if you want to insert/update your Database, then you can go for a JDBC receiver adapter.
Multiple insertions are possible for a JDBC receiver, but multiple Selection queries (different select queries) are not possible for a single JDBC sender adapter.
Just check these links to understand how JDBC adapters work,

A few initial steps required to be followed for your Scenario are:
1. Then create a sender agreement using jdbc o/b interface.
In receiver determination specify ur bpm as receiver.
In interface determination specify the abstract interface tht u created for jdbc.
(u should copy the jdbc interface and then create abstarct interfce of it)
No receiver agreement required for BPM.
2. Create receiver determination, using BPM and the abstract interface for legacy tht u created,
Receiver as legacy system.
Create Interface determination and receiver agreements.
