See attached text file.  I am trying to add in a named colum to my where clause to make it work correctly.  All of this select goes into a datagrid for presentation.

It looks like you're trying to say when both your case condition is met and when your substring > 0.  If this is the case, try the following snippet.

SELECT	at.UPC as UIC, 
	ut.Addr_City as City,
	at.Auth_Para_Dsg as PARA, 
	at.Auth_Line_Dsg as LINE, 
	at.GRADE, 
	substring(at.POSC, 1,4) as DMOS,
	case at.AUTH_PERS_IDENT when 'E' then 'M' when 'W' then 'M' when 'O' then 'M' else 'I' end GENDER, 
	at.AUTH_STR,
	CASE WHEN  ISNUMERIC( case when at.AUTH_DOC_POSN_TITLE like '%(%)%' then substring(at.AUTH_DOC_POSN_TITLE, 1 + charindex('(', at.AUTH_DOC_POSN_TITLE), charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1)) else '0' end ) = 0 THEN 0 
	ELSE 
	case when at.AUTH_DOC_POSN_TITLE like '%(%)%' then substring(at.AUTH_DOC_POSN_TITLE, 1 + charindex('(', at.AUTH_DOC_POSN_TITLE), charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1)) else '0' end  END AS OS,
	at.ASGN_STR,
	at.AUTH_STR + CASE WHEN  ISNUMERIC( case when at.AUTH_DOC_POSN_TITLE like '%(%)%' then substring(at.AUTH_DOC_POSN_TITLE, 1 + charindex('(', at.AUTH_DOC_POSN_TITLE), charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1)) else '0' end ) = 0 THEN 0 
	ELSE 
	case when at.AUTH_DOC_POSN_TITLE like '%(%)%' then substring(at.AUTH_DOC_POSN_TITLE, 1 + charindex('(', at.AUTH_DOC_POSN_TITLE), charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1)) else '0' end - at.ASGN_STR END AS VAC,
	case substring(at.DOC_NBR, 1, 2) when 'NG' then 'TDA' else 'MTOE' End as UNIT_Type,  
	case st.strStat when 'L' then 'Locked' when 'C' then 'Critical' Else '' end as UNIT_Stat
FROM    PERS_UNIT_TBL as ut Inner join
	PERS_AUTH_STR_TBL as at on at.UPC = ut.UPC Left Outer Join
	DotNet.dbo.tblStatUic as st on st.strUIc = at.UPC
where	Substring(at.grade, 1,1) = 'E' and at.UPC = '77726'
  and at.AUTH_DOC_POSN_TITLE like '%(%)%'
  and substring(at.AUTH_DOC_POSN_TITLE, 1 + charindex('(', at.AUTH_DOC_POSN_TITLE), charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1)) else '0' end - at.ASGN_STR END > 0
Order by at.UPC, at.Auth_Para_Dsg, at.Auth_Line_Dsg

The other way I could read your question is that if auth_doc_posn_title is like '%(%)%' then you want to check the substring and include >0, otherwise if auth_doc_posn_title isn't like that, don't bother checking the substring and include it anyway.  If this is what you're looking for, try the below instead.

SELECT	at.UPC as UIC, 
	ut.Addr_City as City,
	at.Auth_Para_Dsg as PARA, 
	at.Auth_Line_Dsg as LINE, 
	at.GRADE, 
	substring(at.POSC, 1,4) as DMOS,
	case at.AUTH_PERS_IDENT when 'E' then 'M' when 'W' then 'M' when 'O' then 'M' else 'I' end GENDER, 
	at.AUTH_STR,
	CASE WHEN  ISNUMERIC( case when at.AUTH_DOC_POSN_TITLE like '%(%)%' then substring(at.AUTH_DOC_POSN_TITLE, 1 + charindex('(', at.AUTH_DOC_POSN_TITLE), charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1)) else '0' end ) = 0 THEN 0 
	ELSE 
	case when at.AUTH_DOC_POSN_TITLE like '%(%)%' then substring(at.AUTH_DOC_POSN_TITLE, 1 + charindex('(', at.AUTH_DOC_POSN_TITLE), charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1)) else '0' end  END AS OS,
	at.ASGN_STR,
	at.AUTH_STR + CASE WHEN  ISNUMERIC( case when at.AUTH_DOC_POSN_TITLE like '%(%)%' then substring(at.AUTH_DOC_POSN_TITLE, 1 + charindex('(', at.AUTH_DOC_POSN_TITLE), charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1)) else '0' end ) = 0 THEN 0 
	ELSE 
	case when at.AUTH_DOC_POSN_TITLE like '%(%)%' then substring(at.AUTH_DOC_POSN_TITLE, 1 + charindex('(', at.AUTH_DOC_POSN_TITLE), charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1)) else '0' end - at.ASGN_STR END AS VAC,
	case substring(at.DOC_NBR, 1, 2) when 'NG' then 'TDA' else 'MTOE' End as UNIT_Type,  
	case st.strStat when 'L' then 'Locked' when 'C' then 'Critical' Else '' end as UNIT_Stat
FROM    PERS_UNIT_TBL as ut Inner join
	PERS_AUTH_STR_TBL as at on at.UPC = ut.UPC Left Outer Join
	DotNet.dbo.tblStatUic as st on st.strUIc = at.UPC
where Substring(at.grade, 1,1) = 'E' and at.UPC = '77726'
  and ((at.AUTH_DOC_POSN_TITLE like '%(%)%' and substring(at.AUTH_DOC_POSN_TITLE, 1 + charindex('(', at.AUTH_DOC_POSN_TITLE), charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1)) else '0' end - at.ASGN_STR END > 0)
   or (at.AUTH_DOC_POSN_TITLE not like '%(%)%'))
Order by at.UPC, at.Auth_Para_Dsg, at.Auth_Line_Dsg

The CASE structure is allowed in WHEN clause, so you should look at its values first and then you may decide if it works or not.

You have duplicate END in your case, try this WHERE:

where      Substring(at.grade, 1,1) = 'E' and at.UPC = '77726'
and       case when at.AUTH_DOC_POSN_TITLE like '%(%)%'
        then substring(at.AUTH_DOC_POSN_TITLE,
                       1 + charindex('(', at.AUTH_DOC_POSN_TITLE),
                       charindex(')', at.AUTH_DOC_POSN_TITLE)  - (charindex('(', at.AUTH_DOC_POSN_TITLE) + 1))
        else '0' end - at.ASGN_STR > 0

You can put that in a CTE expression. Try this:

	case at.AUTH_PERS_IDENT

		when 'O' then 'M' 
		else 'I' end GENDER, 
	at.AUTH_STR,
	CASE WHEN  ISNUMERIC(case when at.AUTH_DOC_POSN_TITLE like '%(%)%'

Tried taht and it always comes up with zero records,  from the sampling I showed it should come up with a few.

Well, you can use my last approach. It will work in both SQL 2000 and 2005.
