Hello,
You can use the following keywords to identify a partition:
PREVIOUS_DAY
CURRENT_DAY
CURRENT_MONTH
PREVIOUS_MONTH
CURRENT_HOUR
PREVIOUS_HOUR
If you need more complex expressions to pick up a specific partition, you would need to use variables in your scenarios.
See the documentation:
http://doc.dataiku.com/dss/latest/scenarios/variables.html
Note that you need DSS production features in your license to use the variables.
