Hi Venkat,
I have changed the sender message type to 0 - unbounded using external definition and target as Idoc standard message with 1: 1 in message mapping.Even I tried vice versa as per above screenshots also.But unfortunately I am getting 2 messages on processing 2 idocs together.
Connectivity is fine since idocs are reaching to PI.
For your information , I tried processing from We19 with 2 messages and in this case am getting 1 message in PI as expected . But using We14 when i process 2 idocs , I am getting 2 messages in PI.
Regards,
Tibin
