## Look Up Value Help

I'm new at DAX.  I am trying to lookup Escalation Multipliers based on Notice to Proceed (NTP Yr) OR Mid-point of Construction (MPC Yr) OR Substantial/Final Completion (SC/FC Year).

In Excel, my formula would look something like this

=IF([@[NTP YR]]="",VLOOKUP([@[SC/FC YR]],Table7,2,FALSE),VLOOKUP([@[NTP YR]],Table7,2,FALSE)) - It was based on just 2 conditions. However, I'm adding another condition in Power BI.

In Power BI, I have created a custom column called Escalation Multiplier. I have Years & corresponding escalation rates in a separate table called Escalation.

If MPC Yr is available, it is to lookup the corresponding year in Escalation Table to pull the value.

If MPC Yr is blank, it is to use NTP Yr to lookup the corresponding year in Escalation Table to pull the value.

If NTP Yr is blank, it is to use SC/FC Yr to lookup the corresponding year in Escalation Table to pull the value.

Currently, I am using the following formula

Escalation Multiplier = lookupvalue(Escalation1[Multiplier],Escalation1[Year],Append1[MPC YR]) || if(isblank(append1[MPC YR]),lookupvalue(escalation1[multiplier],escalation1[year],append1[NTP YR])) || if(isblank(Append1[NTP YR]),lookupvalue(Escalation1[Multiplier],Escalation1[Year],Append1[SC/FC YR]))

Solved it!

switch(TRUE(),not isblank(Append1[MPC YR]),lookupvalue(Escalation1[Multiplier],Escalation1[Year],Append1[MPC YR]),isblank(Append1[MPC YR]),lookupvalue(Escalation1[Multiplier],Escalation1[Year],Append1[NTP YR]),isblank(Append1[NTP YR]),lookupvalue(Escalation1[Multiplier],Escalation1[Year],Append1[SC/FC YR]))
