Hi Olav!
There is currently no way of getting the last event date of a program stage
directly, but there is a function that might help you.
d2:lastEventDate('variableName') - will give you the event date when the
underlying data element was entered. Based on how your program stages and data
elements is structured you might use this function.
Another option that might solve your problem in a simpler way is to use program
rule variables with the "Data element from previous event". But again - only if
you have a data element that you can use for validation in the previous events.
You are also most welcome to make a jira issue requesting a function that does
not rely on the data elements :)
