ECC Connects with SRM and CRM

Hi

our landscape is as below

one ECC systems connects with CRM and SRM as well

now SRMD_VENDOR_MAIN queue is coming to SRM but the same data goes to CRM

why this SRMD_VENDOR_MAIN queue is coming to SRM system.as you aware this queue is not our SRM queue SRMD_VENDOR_MAIN and it belongs to CRM queue.

Have any one faced this issue?
