SAP CPI: How to use Patch operation in HTTP adapter

Hi Experts,

As per my requirement I should use patch operation in HTTP adapter but unfortunately I couldn't find patch operation. I gave a try by using "Dynamic" method and in expression tab I've given data stored in header which is ${header.Branch_ID}

but still no luck. So is there any way of achieving patch operation in HTTP adapter.

Any inputs from you is greatly appreciated.

Thanks,

Vineeth
