Per the example the course is asking the Monthly Summary value for Beginning Inventory to be set to closing balance.

As it is the BEGINNING inventory surely this should be set to Opening Balance?
A summary for the month could then be created which would make sense:
Opening
Less Demand
Plus Receipts
===========
Ending Inventory
===========
I will update the view as prescribed by the course but if anyone has the inclination I would like to understand the logic behind setting the Beginning inventory's summary method to closing.
Kind regards,
