Using an 'IN' function to make a custom column

[Anonymous]

I have column 'Letters,' and I would like to create column 'Contains A' by making a custom column.  I think I should use an IF statement and some type of IN function, but I can't figure it out.

Letters	Contains A
A, B, C	1
A	1
B, C	0
A, B, C, D	1
B	0
C	0
B, C	0

Hi @Anonymous 

Try something like this:

_containsA =
IF(
  CONTAINSSTRING(yourTable[Letters], "A"),
  1,
  BLANK()
)

This will give you flag of the value 1 if [Letters] has A in it, or Blank/Null if not.

By the way, Intellisense is your friend here. If you're looking for something in DAX that helps you identify whether something CONTAINS something else, just start typing CONTAINS and Intellisense will show you if options exist:
