SMQ2 queue stuck in Ready status

Hi Experts,

My scenario is from ECC(RFC/PROXY) to PI Quality system when ever message processed from ECC to PI messages are stuck at ECC SMQ2 queues in READY Status. They won't process automatically untill I release or unlock those queues. Once queues are released  the message processed successfully.

Can you please suggest what changes I need to do to process those message automatically from Queues.

Thanks in Advance and really appricate for your inputs and will be rewarded.

Thanks
