Nicely done Mark Cowne.  My attempt avoids the inequality on date (which makes me nervous) but is otherwise the same.

Here's an article from SSC:

If it were me I'd use BCP, the Bulk Copy Program that comes with SQL Server.

What happens if you add TOP(1)?  Will any row convert or does every row fail?

drop function if exists dbo.test_name_chopper;
go
create function dbo.test_name_chopper(
  @PREFX VARCHAR(10),
  @DELIM VARCHAR(30),
  @AD_STR VARCHAR(500))
returns table as 
return
select
  IIF(PATINDEX(@DELIM,@AD_STR collate Latin1_General_CS_AS)<=0,

Well in my opinion just looking for a comma is risky.  Trying to comma parse the entire string multiplies the risk!  So that seems unnecessary imo.  Here's a safer way...

Give it a try and see!  🙂  Yes it should work like:

select
  substring(@test, 4, charindex(N',OU=' collate Latin1_General_CS_AS, st.some_column, 4)-4) some_name
from
  some_table st;

The safest way to do this imo is to look for the first occurrence of ',OU=' in a case-sensitive way.

declare @testnvarchar(max)=N'CN=Some Person,OU=Sales,OU=Some Company - SK,OU=Companies - Some...

Maybe successively cross apply with partial joins?  Something like:

with
matrix_1(month_nbr, x_group, [1], [2], [3]) as (
    select 1, 'grp a', 1, 1, 1
  ...

Yes, union all works well.  Or you could insert into @Temptable twice.  It's not clear whether the information in the inserted 'Invoice' should contain all of "same informations (ID,DKey,SKey)..." because...

The whole retry loop could be removed in my opinion.  This is a basic upsert.  The variables used for flow of control are deterministic so the retry is not really...

Final answer, shamelessly borrowing from Jonathan, still without CROSS APPLY.  Also, Jonathan's answer with sample data cte included (copy/paste/run).

Well I was close.  Should've summarized from the beginning.  I thought about CROSS APPLY but it seems fussy when there's no TVF because there's still the old ways.  The DISTINCT...
