Calculate Column based on columns from multiple tables

Hi there,

 

Below is my model:

 

 

I would like to calculate a column in the 'inv_unit' table, that gives me the 'srv_event'[placed_time] for each gkey (or row) in the 'inv_unit' table.

 

but because there are multiple 'srv_event'[placed_time] for a given 'inv_unit'[gkey], the criterion for choosing the correct 'srv_event'[placed_time] is where 'srv_event_types'[id]="UNIT_LOAD"

 

Please can someone kindly help me by telling me what my calculated column formula in 'inv_unit' data table should look like to achieve this?

 

Thanks in advance for your help


Wes
