Challenging issue with JDBC sender adapter

Question

Hello Guys
I have this requirement
From Oracle Database I have to read to tables  one for the header and one for the detailes and map the result to one RFC.
I have only  worked with one table at the time with the JDBC sender adapter but never with 2  tables
My challenges are
1 - How I can read the 2 tables at the same select statement , I suppose I have to use a join with 2 identical fields , so far so good ,but how I can handle multiple records
suppose the result is 10 new different records which each of the recored has to be mapped to the RFC , then we will have 10 RFC calls.
how can I do the mapping in this case.
2 - How can I update the 2 tables at the samme time and flag them as processed , as far as I know we can not use 2 update statement in the same JDBC sender
any help will do
Thanks in advance.

Hi
Thanks for the replayes
The RFC is used to create and Invoice Idoc , It has to be one record (Header and Item ) to one RFC.
a JDBC to IDoc can also be used , but we have to update another table in SAP that is why the RFC,
My doubt is how the Data type for the sender JDBC should look like , as mentioned I have 2 tables to fetch data from
<Invoice>
<Header> 1 -- 1
<f1>
<f2>
<f3>
</Header>
<Item> 1--n
<f1>
<f2>
<f3>
</Item>
</Invoice>
The sender JDBC returns
<Invoice>
<row>
<f1>
<f2>
<f3>
</row>
</Invoice>
How can I replicate the data type to meet the JDBC sender structure.
and regarding the mapping do I have to change the occurrunce to 0 -- unbounded
regarding the update Ragu is right in his suggestion
Table1 can be used as primary table, Table2 can be used as Secondary table.. u will have key field to link both table.
So Just Updating only Primary Table(Table1) will helps on this.
Thanks.
