Approval Date less than the Order Date (two Tables)

[Greg5]

Hello,

I'm creating an SLA indicator for this, I need to do this formula below.

I have two tables, one containing the order number, order creation date and request number that originated the order, the other has the approval date of the requests that some have a re-approval date after the creation date of the request.

I need to bring to the order table, the approval date that is the last approval date before the order creation date.

RC - APPROVAL DATE
1 10/12/2022
2 10/07/2022

RC - APPROVAL DATE
1 10/08/2022
1 10/14/2022
2 10/05/2022
2 10/06/2022
2 10/10/2022

Hi @Greg5 ,

According to your description, seems you messed up the data. I create a sample.

Order table:

Approval table:

Here's my solution. Create a calculated column in Order table:

Column =
MAXX (
    FILTER (
        'Approval',
        'Approval'[Request num] = EARLIER ( 'Order'[request number] )
            && 'Approval'[APPROVAL DATE] <= EARLIER ( 'Order'[order creation date] )
    ),
    'Approval'[APPROVAL DATE]
)

Get the correct result:

I attach my sample below for your reference.
