I would like to use a Project Variable to explicity state which partition of a recipe I would like to run.  See the attached  screenshot - I used the variable expansion syntax but DSS did not interpret it correctly.  Is there a way to do this?

Actually, you won't be able to use your project variable here. However it's possible to do it within a scenario, from the step "Build", you can select your partitioned dataset and then use you project variable to define your partitions.

Hi, Indeed the syntax for referencing variables in the partition screen is ${myVariable}. Have you checked that the variable is actually defined? Cheers, Alexandre
Yes, I have checked that the Project Variable is defined - it appears in the Project Variables and in the Variables section of the Python recipe that I am trying to run.  However, when I attempt to build the dataset, it appears that it is trying to build against the partition "${current_month}" rather than "2019-01", which is what the variable points to:

compute_partitioned_output (${current_month})

I also get the following error after launching the dataset build:

Error in Python process: At line 8: <type 'exceptions.ValueError'>: No JSON object could be decoded
