EAI Siebel Adapter - Query - to return subset of data using single IO

Hi,

We have a requirement to fetch Accounts only in one inbound call to Siebel, Accounts & Addresses in Another call and Accounts & Contacts in a third call.

The Siebel Inbound Service takes Siebel Message as input and should return the above combinations accordingly.

We've tried with one Single IO having Account, Address & Contact nodes but it seems like not working. Is there any way to fetch the nodes which are required using a single IO having all the Integration Components?

Below is the example that was tried

EAI Siebel Adapter 'Execute' method was used and below is the Siebel Message
