The 'project' value is 'NEW_VALUE' based on 'ESN' and 'FIELD' value equals 'A'.

And between two 'FIELD' values  euals 'A' based on 'CREATED_TS', the 'project' value euqals the older 'NEW_VALUE' value.

Hi,

Check if this works:

project = 
VAR v_lag = CALCULATE( MAX( Data[NEW_VALUE] ), FILTER( Data, Data[CREATED_TS] <= EARLIER( Data[CREATED_TS] ) ) )
RETURN
IF( Data[FIELD] == "A", Data[NEW_VALUE], v_lag )

Here's what i got:

Hi,

 

I think "MAX( DATA[NEW_VALUE] )" does not works if "NEW_VALUE" like picture as below.
