Column with multiple conditions

[nniphadk]

Good Morning 🙂
I am struggling with creating a column/conditional column
Conditions: 

● BD: TR Type = CRD, TR Code = 123, BK Trx # = 41, TR Text Does Not Contain "DCD"
● MD: TR Type = CRD, TR Code = 123, BK Trx # = 41, TR Text Contains "DCD"
● LD: TR Type = CD, TR Code = 125, BK Trx # = 54
● BMDS: TR Type = CD, TR Code = 123, BK Trx # has more than 6 digits (excl. leading zeros)

I have tried to do a custom column in Power Query is there any other method to achieve what I am trying to do.

TR Type	TRCode	BKTrx #	TR Text
CRD	456	1.91E+13	ST
CRD	123	41	DCD
CRD	123	41	DCD
CRD	123	1	DCD
CRD	123	41	DCD
DBT	123	1	DCD
DBT	123	41	DCD

Here is a sample data set.

@nniphadk That would be one long, nasty if statement in Power Query. DAX might be cleaner:

Column = 
  SWITCH(TRUE(),
    [TR Type] = "CRD" && [TR Code] = 123 && [BK Trx #] = 41 && NOT(CONTAINSSTRING([TR Text], "DCD")), "BD",
    [TR Type] = "CRD" && [TR Code] = 123 && [BK Trx #] = 41 && CONTAINSSTRING([TR Text], "DCD"), "MD",
    [TR Type] = "CRD" && [TR Code] = 123 && [BK Trx #] = 54, "LD"
  )

If you can provide sample data as text in a table, could be more complete with the solution. The last case is going to be similar although the leading zeros could be an issue. Are there a constant number of leading zeros or is it variable?
