Process ID in Sync Start Process

Question

Hi Everyone , 
 I have a sync start process(Process Id is used to select the Process Model) in my Parent Process. Now I am not able to save the Output. PVs are not shown in pv!.

For Outputs, this is the expected configuration of start process mode 
 
 For Save Target, select a process variable to contain the output. 
 For Value, select the ProcessInfo property that you want to store in the save target. Like ac!processInfo.pv. processVariable . 
 
 So after completion whichever pv data you want Response to have, refer to that using the processInfo property. The type of Response and pv should match for it to be available for configuration .

 Are you saying that the data type of "pv!Response" is integer ? Because it would need to be that type (specifically) in order for pp!id to show up in your output selection.

Hi Anusuya in your screenshot the refresh icons are missing which are genrally there on the setup tab. Can you try to delete this start process node and drag a fresh one from the palette to setup this again and see if pv as well as refresh icons are available.

 Any return value you hope to directly map from a PV value would need to (Exactly) match in data type with the PV value. However, if you enter a valid expression for the subprocess value, you can access values that don't exactly match 1:1 with the data types in the parent process - this is very useful, but you have to know what you're doing of course or else the result will potentially seem nonsensical.

Are you able to provide screenshots of what I asked for before? That would help pinpoint your issue. If your target process model is selected via an expression, then you must enter the ac!processInfo.pv.myPv as an expression, since we can not populate the PV options when the model to start is selected via expression.

It looks like this is not a configuration issue. I would recommend deleting the PVs from both processes and recreating them. Then save and publish both processes, reopen the main process, and try to configure it again. Let us know if the issue still persists.
