Source = Sql.Database("10.16.89.71", "DWH"),
//Parameter
_date_start = Date.ToText(
#date(Date.Year(DateStart), Date.Month(DateStart), Date.Day(DateStart)),
"yyyy-MM-dd",
null
),
_date_end = Date.ToText(
#date(Date.Year(DateEnd), Date.Month(DateEnd), Date.Day(DateEnd)),
"yyyy-MM-dd",
null
),
_pol_status = PolStat_Param,
//Native SQL
_function = Value.NativeQuery(
Source,
"SELECT * FROM [dbo].[Fn_TAProductionReport](@date_start,@date_end)
WHERE [PolicyStatus] = @pol_status",
[date_start = @_date_start, date_end = @_date_end, pol_status = @_pol_status],

How about this:

Source = Sql.Database("10.16.89.71", "DWH"),
//Parameter
_date_start = Date.ToText(
#date(Date.Year(DateStart), Date.Month(DateStart), Date.Day(DateStart)),
"yyyy-MM-dd",
null
),
_date_end = Date.ToText(
#date(Date.Year(DateEnd), Date.Month(DateEnd), Date.Day(DateEnd)),
"yyyy-MM-dd",
null
),
_pol_status = PolStat_Param,
//Native SQL
_function = Value.NativeQuery(
Source,
"SELECT * FROM [dbo].[Fn_TAProductionReport](@_date_start,@_date_end)
WHERE [PolicyStatus] = @_pol_status",
[date_start = @_date_start, date_end = @_date_end, pol_status = @_pol_status],
