In PowerServer, you cannot use a shared object (SharedObjectGet, SharedObjectRegister, and SharedObjectUnregister) in the client app to simulate an asynchronous call to the PowerServer Web APIs.
For example, if you perform a database update in a shared object, the update may be successful in the traditional C/S application, but will fail in the PowerServer installable cloud app.
Note: PowerBuilder features added after version 12.6 do not support multi-threading.
