To accomplish this, you'll want to make sure that you have a date dimension table that you can link both columns to. One of them will be inactive because you can only have 1 active relationship between 2 tables, and that's ok.
You can make use of the USERELATIONSHIP function to use the inactive relationship for the measure to sum the item that's related to that date.
For example, lets say you connect both dates to the date dimension table and you want the order date to be the active relationship and the Delivery date to be the inactive date. You would then write 2 different measures for Ordered and Delivered.
Ordered =
COUNTX(table, table[Incident])
Delivered =
CALCULATE (
COUNT( table[Incident]),
USERELATIONSHIP(calendar[date], table[Delivery Date]))
Then you can create a table visual with the date from the date dimension table as the axis and the 2 measures you just created as the values.
