How to return the latest text value depending on a date range

[Cbutler]

Hi all, 

I can't work out how to return the latest text value in my table depending on a date range. So my table is showing PPE concernes from providers, they will not anser this question each time just complete if the answer changes - I want to show the last text input

eg 

Provider name	Date	Answer (Yes/No)
A	01/05/2020	Yes
A	02/05/2020
A	03/05/2020
A	04/05/2020	No
A	05/05/2020	Yes
B	01/05/2020
B	02/05/2020	No
B	03/05/2020
B	04/05/2020	Yes
B	05/05/2020
C	01/05/2020	No
C	02/05/2020
C	03/05/2020	Yes
C	04/05/2020	No
C	05/05/2020

So.....
if date range selected is 01/05/2020 to 05/05/2020 then Provder A = Yes, B = Yes, C = No.
If date range selected is 01/05/2020 to 03/05/2020 then Provider A = Yes, B = No, C = Yes.
If date range selected is 01/05/2020 to 01/05/2020 then Provider A = Yes, B = "Blank/Not completed", C = No

Can anyone help me please......?

I believe you want Lookup Min/Max: https://community.powerbi.com/t5/Quick-Measures-Gallery/Lookup-Min-Max/m-p/985814#M434

Or LookupValue Range: https://community.powerbi.com/t5/Quick-Measures-Gallery/LOOKUPVALUE-Range/m-p/974201#M430

@Cbutler , try like

LastNONBLANKVALUE(Table[Date],Max(Table[Answer])

or

maxx(summarize(table,table[Provider name],"_1",LastNONBLANKVALUE(Table[Date],Max(Table[Answer]))),[_1])

@amitchandak  can you tell me how to display the "date" of the last non blank value from the same table? 

[Greg_Deckler]

@Cbutler That's the Lookup Min/Max pattern I sent, https://community.powerbi.com/t5/Quick-Measures-Gallery/Lookup-Min-Max/m-p/985814#M434
