Expression.Error: We cannot convert the value (Function) to type Logical

Question

I am trying to apply a user's manually input fields as a filter to data connection (called IKX).

Here is an example of the user input data:

BUYER CODE FILTER
104
800

I have a table that applies the code format of the power query filter:

BUYER CODE FILTER FORMAT	FORMULA
[BUYER_CODE] = 104	IFERROR(IF(LEN(InputBuyerCodes[@[Buyer Code Filter]])>0, "[BUYER_CODE] = " &InputBuyerCodes[@[Buyer Code Filter]], ""),"")
or [BUYER_CODE] = 800	IFERROR(IF(LEN(InputBuyerCodes[@[Buyer Code Filter]])>0, " or [BUYER_CODE] = " &InputBuyerCodes[@[Buyer Code Filter]], ""),"")

Then a table that concats these fields:

CONCAT BUYER CODE FILTER FORMAT	FORMULA
[BUYER_CODE] = 104 or [BUYER_CODE] = 800	CONCAT(Table2[Buyer Code Filter Format])

In power query I have a connection to the "CONCAT BUYER CODE FILTER FORMAT" table that drills down the table to just [BUYER_CODE] = 104 or [BUYER_CODE] = 800 called ConcatBuyerCodeFilterFormat

To apply the filter to the IKX data, I added the below step:
=Table.SelectRows(Source, each (ConcatBuyerCodeFilterFormat) )

and get the error
Expression.Error: We cannot convert the value "[BUYER_CODE] = 104 o..." to type Logical. Details: Value=[BUYER_CODE] = 104 or [BUYER_CODE] = 800 Type=[Type]

Any ideas on how to resolve?

Answer 1

See if this helps you. It shows how to filter, with the filter definition in another variable

let Source =#table({"Column1"}, {{"a"}, {"b"}, {"c"}}),
crit="[Column1] = ""a""",
#"Filtered Rows" = Table.SelectRows(Source, Expression.Evaluate("each "&crit))
in #"Filtered Rows"

All that said, if you start off with the first filter table, why not just merge that against your larger data.table and remove the rows with no match?
