Smile RDMA WRITE WITH IMMEDIATE Data not generates any event at remote side

I Posted recive work request & wait for geting any complition event at remote side, And local side I perform rdma write with immediate data operation, as per InfiniBand Architecture Specification Volume 1

Normally an RDMA operation does not consume a receive WQE at the destination, but there is one exception. That is for an RDMA WRITE operation which specifies immediate data. Immediate data is 32 bits of information that is optionally provided in a SEND or RDMA WRITE instruction,transferred as part of the operation, but instead of writing the immediate data to memory, the data is treated as another piece of status information
"RDMA Write with immediate data does involve the destinationís receive work queue.and returned as a special field of the RECEIVE CQE status. This means that an RDMA WRITE with immediate data will consume a RECEIVE WQE at the destination."

But I cant get any event at remote side

Please help me

Wating for replay ..............Thanks in advance
