I did following steps
ESR
1. Created two target messages
2. Created Two target inbound interfaces
3. Created Message mapping using with multiple target messages, changed signature occurrence to 0 : unbounded , and mapped to source node to target nodes
4. Created operation mapping with one source to two target interfaces
EB
1. Created one business components and assigned one sender and two receiver service interfaces
2. Created Two receiver communication channel
3. Created One receiver determination
4. Created One interface determination , added two inbound interfaces with one operation mapping (Multiplicity is blank )

Thanks Gouri ,
My IDOC structure (Source Message Type)
  HEADER_SEG Node (0:9999) -
> MT_HEADER ( 0:unbounded) (this one of target message type)
                                                                HEADER_FLDS  (Element - Main hierarchy)
         FLDS----
>  FLDS
ITEM_SEG Node (0:9999)  -
>MT_ITEM(0:unbounded ) (this is another message type)
                                                                ITEM_FLDS (Element - Main hierarchy)
         FLDS----
>  FLDS
I tried with the below mappings
                HEADER_SEG Node -
>MT_HEADER
                HEADER_SEG Node -
> HEADER_FLDS (element )
                ITEM_SEG Node -
>MT_HEADER
                ITEM_SEG Node -
> ITEM_FLDS (element )
2. method
                HEADER_SEG Node -
>MT_HEADER
                                                       HEADER_FLDS (element )(not mapped)
                ITEM_SEG Node -
>MT_HEADER
                ITEM_SEG Node   ITEM_FLDS (element )(not mapped)
