DAX - Date before

[Monicam]

I am attempting to pull the date of the 101 Movement type that comes directly before a 102 movement.

I have no issues determining the Max date for an order # by movement type however cannot for the life of me determine how through DAX to pull the Maximum Date for Movement Type = 101 that comes before the 102 Movement Type.  Below is an example of my data.

 

Thank you

Is this going to be a measure or a calculated column? And if a measure, then what will happen if there are many different orders visible in the context? How to decide which date to return?

Create a measure with:

a variable that holds the date of the type = 102 record-> _102Date

Return the largest date from the filtered table of type = 101 and PostingDate < _102Date
