Lookup

[unnijoy]

i have 2 tables. one is Active HC and other is Inactive HC.

In Inactive HC i don't have L2 name. but it is available on Active HC table. i need to find it based on the below logic.

Logic- From inactive table we have to take the Empid and go to active Active table. And apply 2 filter. 

Fiter 1 =first we have to get the previous month of the report date which is mentioned in Inactive ( in our case previous months based on Inactive is Jan - 1 - 2021.)

Filter 2 = In Active table filter for "Opening"

so based on the above table i will go to Inactive table and take the EMPID 122. and the Report date is Feb - 1- 2021 ( In Inactive Table). now i have to go to Active table and first filter is previous month. so i will select Jan-1-2021( Active Table). and Filter 2 is "Opening" ( Active Table). and it will give me L2 as Jack.

How to get this working

pls try this

L2 = 
MAXX(FILTER(ALL(Active),Active[Report Name]=EDATE(Inactive[Report Name],-1)&&Active[OP/CL]="Opening"&&Active[EMPID]=Inactive[EMPID]),Active[L2])

Create a new table from Table one if it has all emp

summarize(table, Table[empid], table[L2])

Join it both the tbale on employee id

hi @amitchandak ,

Thanks for your reply.

I need to create a calulated column for L2. like a lookup based on filter. Can you please help me with that.

@unnijoy , a new column in inactive 

maxx(filter(active , active[empid] = inactive[empid]), active[l2])

@amitchandak  in the above dax i think we forgot to add the other two filter, one is select only opening in Active and second is we have to select the previous month of the report date in Inactvie and based on the previous month we have to lookup from Active. 
that means if in Inactive table the report date is Feb - 1- 2021 then we have to select Jan -1 -2021 in Active table and filter only Opening and then based on the EMPID we have to select the L2 from Active.
