Hi there,
I am hoping someone can help me with a conditional column that I have created in Power Query. I have the following table (called This Month) and I am trying to combine the first two columns and create the conditional column.
The logic is that the ConditionalColumn = Active.a column, however if Active.a column = null then the ConditionalColumn = Inactive.b column.
Please see my example below:-
This Month
Table1 (Active a).AC Cust Num | Table1 (Inactive b).AC Cust Num | ConditionalColumn |
5 | 5 | 5 |
5 | 4 | 5 |
null | 3 | 3 |
null | null | null |
null | 1 | 1 |
I have used the following in the ConditionalColumn:-
= Table.AddColumn(#"Removed Duplicates1", "Custom.2", each if Text.From([[#"Table1 (Active a).AC Cust Num"]])<> null then [#"Table1 (Active a).AC Cust Num"]
else if Text.From([[#"Table1 (Active a).AC Cust Num"]])= null then [#"Table1 (Inactive b).AC Cust Num"]
else "")
However this results in the error message ‘We cannot convert a value of type Record to type Text’. All columns are currently formatted as text as it may include alphanumeric characters in the future.
Any ideas on how I can merge the values from two columns into one will be greatfully received!
Many thanks

Hi @ClemFandango,
When dealing with null (the absense of a value) you can use coalesce (??), to illustrate:
Table.AddColumn(#"Replaced Value", "Custom", each [#"Table1 (Active a).AC Cust Num"] ?? [#"Table1 (Inactive b).AC Cust Num"])
The error you reported is most likely due to the double set of square brackets within your syntax.
