Select the processing mode to use

Requests can be processed in synchronous mode or in asynchronous mode, regardless of the deployment pattern associated with the Adapter service.

The fundamental difference between adapter request processing in asynchronous mode versus adapter request processing in synchronous mode is:

Start of changeRunning asynchronously means that data can only be added to the output message after the execution of the last server adapter. If your modeled flows require data to be moved to the output message between the invocation of server adapters, i.e. in mid-flow, use the synchronous processing mode. This restriction is removed when you apply APAR PK32131.End of change

Under normal circumstances, if you are invoking the runtime environment using a CICS-supplied interface, you cannot run in asynchronous mode.
