I'm trying to calculate return rate (items received/ items delivered), but aggregate them by day. However, there are multiple receiving lines for each event, and only one input for items delivered. I'd normally do a formula based off a pivot table but I'm not sure how to do that in Airtable.
Here's an example of the table I have
Event Name | Items Received | Items Delivered | ||
Timestamp 1 | x | 10 | 40 | |
Timestamp 2 | x | 20 | ||
Timestamp 3 | y | 40 | 50 |
What I need is Line 1 & Line 2 added together for Items Received, and divide that number by line 1 of items delivered.
How do I achieve this?
