Using dax to get latest value from another table

[lalTel20]

I'd like to update table A with values from Table B.
Requirement - to update the latest [Value] based on [Created] where [value] contains 'Quote'.
Catch is, if on the same date quote is sent and approved, then table A needs to be updated with Quote Approved. What is the best way to get the desired outcome.

Quote_Sub = 
VAR CaseNumber = 'A'[CASE NUMBER]
VAR SUB_Table =
    CALCULATETABLE (
        SELECTCOLUMNS (
            FILTER ( B, B[Case Number] = CaseNumber ),
            "Start Date", B[Created],
            "Sub Value", B[Value]
        ),
        CONTAINSSTRING ( DCM_METRIC_INSTANCE[Value], "Quote" )
    )
VAR Quote_A = MAXX(FILTER(SUB_Table, [Sub Value] = "Quote Approved"),[Start Date])
VAR Quote_Ex = MAXX(FILTER(SUB_Table, [Sub Value] = "Quote Expired"),[Start Date])
VAR Quote_R = MAXX(FILTER(SUB_Table, [Sub Value] = "Quote Rejected"),[Start Date])
VAR Quote_Es = MAXX(FILTER(SUB_Table, [Sub Value] = "Quote Escalated"),[Start Date])
VAR Quote_S = MAXX(FILTER(SUB_Table, [Sub Value] = "Quote Sent"),[Start Date])

VAR max_date = MAXX({Quote_A,Quote_Ex,Quote_R,Quote_Es,Quote_S}, [Value])
VAR max_value = 
calculatetable(
    FIRSTNONBLANK(SELECTCOLUMNS( FILTER(SUB_Table,[Start Date]=max_date),
"max Value",[Sub Value]),[max Value])
)
return max_value

Hi @lalTel20 ,

You can create a calculated column as below in table A, please find the details in the attachment.

Quote_Sub =
VAR _acnum = 'A'[CASE NUMBER]
VAR _maxdate =
CALCULATE ( MAX ( 'B'[Created] ), FILTER ( 'B', 'B'[CASE NUMBER] = _acnum ) )
VAR _count =
CALCULATE (
DISTINCTCOUNT ( 'B'[VALUE] ),
FILTER (
'B',
'B'[CASE NUMBER] = _acnum
&& 'B'[VALUE]
IN { "Quote Approved", "Quote Sent" }
&& 'B'[Created] = _maxdate
)
)
RETURN
IF ( _count = 2, "Quote Approved", 'A'[Value] )

If the above one is not your expected one, please provide some sample data (exclude sensitive data) in the table A and B with Text format and your expected resultwith backend logic and special examples. It is better if you can share a simplified pbix file with me. You can refer the following thread to upload your file in the community. Thank you.

@lalTel20 , Is there a preference when date is the same

example measure

new column =
var _max = maxx(filter(Table, [casenumber] = earlier([casenumber]) ), [Created])
return
maxx(filter(Table, [casenumber] = earlier([casenumber]) && [Created] = _max), [Value])

Hi @amitchandak 
Thank you for your response. Yes the preference is Quote sent gets the least preference, since after the quote is sent, it can be rejected, accepted, escalated or expired on the same day. And it is not always necessary that there will be a subsequent event for a casenumber. In such scenario the atest stage would be quote sent.
