SOAP to RFC message duplication records

Hi Folks,

I am working on SOAP to RFC scenerio . It is synchronous scenerio.

My mapping structure is

HEADER_IN

Datatype

salesorg

division

distrchannel

ITEM_IN

item

ITM_NUMBER

MATERIAL

TARGET QTY

PARTNERS

item

PARTN_ROLE

PARTN_NUMB

CONDITIONS_IN

item

ITM_NUMBER

COND_TYPE

COND_VALUE

In this structure if i pass 1 record it is successfully creating sales document no..My BAPI is the custom one need to create quotation contract.

In this structure i wanted to SEND data twice in ITEM_IN and CONDITIONS_IN TWICE ...

how to do mapping for this...

Regards
