Select single row of data for each ID in Select Statement
I have a need to select a single row of data based on a date range from field UDF_Date_Data for each ID to use as a dataset in my SSRS report. So I need the following Columns. That being said the UDF_FIELD Stores the names of the columns I need "In Bold Below" so I get multiple rows as seen in my data set for an ID so for instance I need all of ID 7482 in one row

basing a where clause of a value returned by a UDF, and that value isn't on every row, means you probaby have to scan the entre table multiple times, and you cannot get indexes help make this efficient becuse of the function call(s)
Looks pretty bad for performance.
If you continue to proceed down this path it is going to be VERY INEFFICIENT
Personally I am concerned about the performance characteristics, especially as I don't know anything bout your UDF

Do you know what that error message means? If not you should really learn how to deal with it (it will save you a lot of time).
In one of the queries I provided there is more than one table (or derived table) that has the column JoinFromHdrPKey and because there is more than 1 reference it is "ambiguous" if you don't specify which one of those 2 columns you want to use
, CTEraw AS (
SELECT
t.JoinFromHdrPKey
, t.UDF_FIELD
, t.UDF_Char_Data
, t.UDF_Date_Data
, t.UDF_Numeric_Data
FROM [dataKLL].[dbo].[KLL Extender UDF Values with Data] t
INNER JOIN CTEid r on t.JoinFromHdrPKey = r.JoinFromHdrPKey
)
where you see the yellow highlight is where I forgot to use a specific alias to ensure the query wasn't ambiguous
In truth production grade code should explicitly specify where all columns come from - this is a best practice sometimes missing from our proposed solutions

Understood, So I just about have this where it needs to be however I have records that do not contain any dates 16 thru 20. Why are these displaying? See sample data

That's not data, it is a result.
I can't tell you why without access to the tables.
Start small, what does this return?
If yes, then the next bit
