Update Constant Smart Service

Hi all

I need some help on using the Update Constant Smart Service.

The constant in question contains a decimal value intended to be a threshold that a user can change when necessary.

I've created a process model with a start node, a user task, the Update Constant smart service and an end node.

The process model has a variable of type decimal called threshold.

Running the process completes without error, and the changed threshold variable is captured correctly.

However when I check the constant, the previous value remains unchanged.

The Smart Task is configured with the name of the constant and the threshold process value as inputs.

Any advice or examples will be greatly appreciated!

Regards

Stephen
