Attached is a dummy example creating a data entity from the excel file with dates and selecting calendar time in run control.

I am getting the following exception when I try to use CalendarTime from the excel file. Is there a specific calendar format I need to be using while importing data from excel? -------------------------------------------------------------------------------- Level 0 Exception ------------------------...

That's fantastic. I appreciate it-it will be very helpful.

Thank you so much @tomfid! Data Entities is what I needed.

Thanks, good question. I am looking to use it as a driver for now. I anticipate I will also use it to compare what the model is generating in other models.

Any ideas? I'm new to ventity but know how to do this in OO languages using functions.

Thanks for the reply. Here is an example of data. We start out with 10 cattle in the first month. In the second month, a few cattle have moved pastures e.x. c001 is now in p002 and some are dead (c008 and c010), and we bought a new cow c011 to pasture p004 and pasture p003 is now empty. Let's assume...

What's the best way to calibrate with entities and time-series data in Ventity while still maintaining collections? For example, how can I use time series data in which a particular cow moves to a new pasture or dies and leaves the farm and new cows are imported?
