MINX with multiple conditions

hi,

I have a table that i am trying to get the date from the previous row. To make it work properly I created an index column. This index column is responsible to classify the information, based on the id, event and date1. 

Here's an example:

 

 

This is how it should work, but the datefromprevious is returning the same date for both rows.

like this:

 

 

I'm trying to add one more condition in this code, but the "Filter" function only allows me to work with 2 conditions.

I tried to use Calculate function, but it seems to have some kind of incompatibility with MINX function and I can't filter either.

this is the code:

NewColumn = MINX(FILTER(Table[ID] = EARLIER(Table[ID]) && [Index] = EARLIER([Index])-1), [Date1])
 
How can I use multiple filters in this case?

    Hi Anonymous ，

     

    Try this calculated column:

     

    DATEFORMPREVIOUS = 
VAR __cur_id = 'Table'[ID]
VAR __cur_event = 'Table'[EVENT]
VAR __cur_index = 'Table'[INDEX]
VAR __result =
    CALCULATE (
        MIN ( 'Table'[DATE1] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[ID] = __cur_id
                && 'Table'[EVENT] = __cur_event
                && 'Table'[INDEX] = __cur_index - 1
        )
    )
RETURN
    __result

      Thank you for your help!

      I'm trying to apply this solution into the real case, but it seems to not work because the "relation" parameter from offset has duplicated lines. How can I send you the file back with a table that is more like the real case?

    Hi,

    If for an ID and event combination, there can never be a duplicate entry in the Date1 column, then the Index column is not required.  Try this calculated column formula

    Previous date  = calculate(max(Data[Date1]),filter(Data,Data[id]=earlier(Data[id])&&data[event]=earlier(data[event])&&data[date1]<earlier(data[date1])))

    Hope this helps.
