Need help with calculated column.

Hello All. I have to create a calculated column using the below excel formula. How can i achieve this in power bi? Any help would be much appreciated.
Thanks in Advance!

Excel Formula:-

=IF(SUMPRODUCT(--ISNUMBER(SEARCH({"DTW"},M7)))>0,DATEVALUE(I7),
IF(OR(I7="",ISERROR(T7),SUMPRODUCT(--ISNUMBER(SEARCH({"ITW"},M7)))>0),1,
IF(WORKDAY(I7,T7)<TODAY()-3,2,
WORKDAY(I7,T7))))

In power bi table, these excel columns represent as below :

M7 = deliver_code (M7 column in excel, represents "deliver_code" column in power bi table)
I7 = ets_to_wh (I7 column in excel, represents "ets_to_wh" column in power bi table)
T7 = Estimated_transit_times (T7 column in excel, represents "estimated_transit_times" column in power bi table)
