SAP Fiori GUI transactions - Automatic execution when passing parameters

Hi,

We are using SAP GUI for HTML in Fiori 2.0 and are passing/prefilling fields in a transaction via URL parameters. When we're passing parameters, the transaction automatically executes.

How can we pass url parameters without executing the transaction on startup?

I guess I have to set some parameters in the Target Mapping. Startup action can be set with the parameter DYNP_OKCODE. Setting this to false does not help.
