Date diffs in the same column

Hi Everyone,

 

I have a dataset where I am trying to calculate the user response time to dealer note using the note date of every action.

 

Here is my sample data look like, I've calculated this in hive query using lag, lead, and min window functions, but my user wants to see this in Power BI.

 

This is what I tried so far.

 

I've created a "user note date" measure to get the first response of the User response 

user note date = CALCULATE(MIN(Query1[Note Date]),ALLEXCEPT(Query1,Query1[incident],Query1[Action Type]),
LEFT(Query1[lastuser],1) in {"U"} )
 
Dealer Note Date  = 
CALCULATE(
MIN(Query1[pdate]),
FILTER(ALLEXCEPT(Query1,Query1[incident],Query1[action_type]),
Query1[action_type] in {
"DLR_CUST_Update"
))

 

I am getting this error from Dealer Note Date Measure, I am not understanding what's wrong with the above calculation.

 error: A single value for column 'Action Type' in table 'Query1' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min

Hi @Sharma0815  - 

 

Try this measure.  The ALLEXCEPT inside the filter "disconnects" from the original Query1 table, causing the error message you are seeing.

 

DealerNoteDate =
CALCULATE (
    MIN ( Query1[Note Date] ),
     KEEPFILTERS ( Query1[incident] ),
     FILTER (
        Query1,
        Query1[Action Type] IN { "DLR_CUST_Update" }
    )
)
