I am using the following to establish a new conditional column in Power Query:
= Table.AddColumn(#"Filtered Rows3", "LC19", each
if[FY18]= #date(2017, 7, 1) and [FY19] = #date(2018, 7, 1) then "Retained"
else
if[FY19]= #date(2018, 7, 1) and [First Gift Date]>= #date(2018, 7, 1) then "New"
else
if[FY18]= #date(null) and [FY19]= #date(2018, 7, 1) and [First Gift Date]<= #date(2017, 6,30) then "Reactived"
else "N/A")
And I keep receiving the folowing Expression.Error: 1 arguments were passed to a function which expects 3.
Details:
Pattern=
Arguments=[List]
All the referenced columns are formatted as type Date - what am I missing?
Solved! Go to Solution.
To explain further, your error message is because:
#date(year, month, day) requires three arguments.
#date(null) has only one argument
Of course, #date(null,null,null) would also be invalid as the arguments for #date(...) need to be of type number and each within a certain range of numbers, and null cannot be converted to a number.
As others have pointed out, you can just use if [FY18]=null ...

To explain further, your error message is because:

Of course, #date(null,null,null) would also be invalid as the arguments for #date(...) need to be of type number and each within a certain range of numbers, and null cannot be converted to a number.
As others have pointed out, you can just use if [FY18]=null ...
Instead of using
if[FY18]= #date(null)
Use
if[FY18]= null
Your issue is caused by using #date(null), which is invalid. Replace it with null for null checks. Here's the corrected code:
= Table.AddColumn(#"Filtered Rows3", "LC19", each
if [FY18] = #date(2017, 7, 1) and [FY19] = #date(2018, 7, 1) then "Retained"
else if [FY19] = #date(2018, 7, 1) and [First Gift Date] >= #date(2018, 7, 1) then "New"
else if [FY18] = null and [FY19] = #date(2018, 7, 1) and [First Gift Date] <= #date(2017, 6, 30) then "Reactivated"
else "N/A"
)
@Nspiler
in the following line, you have used #date(null) which is not acceptable, try this way
if [FY18]= null and [FY19]= #date(2018, 7, 1) and [First Gift Date]<= #date(2017, 6,30) then "Reactived"
You may try [FY18]= "" also
