JDBC to IDOC using BPM

Question

Hi Experts,
I am doing the scenario JDBC to IDOC
Note: i need a solution without stored procedures
My requirement is , in sender JDBC side
1) We need to select data from 3 tables from the DB ( I think we can do this by JOIN query specified in the channel)
2) after selecting data we need to update all 3 tables
(I think we can't do this, as we have only one update option in the sender JDBC channel). So i want to go for BPM.
Can we do like this...??
2 mappings:   
--> sender JDBC o/p structure (MT-1)   to  IDOC structure(MT-2)                                         (MM-1)---->  (IM-1)
--> sender JDBC o/p structure (MT-1)  to  JDBC update structure (for 3 tables) (MT-3)                 (MM-2) ----> (IM-2)
BPM:
MT-1                    (IM-1)                                                     (IM-2)
Receive           Trnsformation             AsyncSend to R/3             Transformation             Async Send to JDBC(Receiver)
  Step                    Step1                                                   Step2
MT = Message Type;   MI = Message Interface;    IM = Interface mapping;    MM = Message mapping

Answer 1

u do not require a BPM..
the method that u specified is right..
mappings:
--> sender JDBC o/p structure (MT-1)   to  IDOC structure(MT-2)                                         (MM-1)---->  (IM-1)
--> sender JDBC o/p structure (MT-1)  to  JDBC update structure (for 3 tables) (MT-3)                 (MM-2) ----> (IM-2)
just in the 2nd mapping that updates the tables the receiver service is same as the sender ..
also specify both the mappings in the interface determination...first the update mapping and then the Idoc one and click the maintain order at runtime so that Idoc is trigeered only after update mapping is done..
