Summary functions are restricted to the SELECT and HAVING clauses only.

Hello Everyone , I Have This Block of code that i'm trying to run :

Proc Sql;
Create Table Work.Tbl_Dt_Tip_Count As
      Select
            Prep.Date
          , Prep.Name
          , Count(distinct Code || name || put(Year, 8.)) As Count
	  From
	     (
		    Select 
			      A.Date
			    , B.Name
				, B.Code
				, B.Year
		 From 
	          Work.Want_Day A
 	  Left join
	          Ext_Data.Tbl_Date B
          
		  on  Date >= min(dt_start)
		  and Date <= Max(Dt_end)
   ) Prep
      Group by

            Date
          , Name
Quit;

but i ran onto this error :

Summary functions are restricted to the SELECT and HAVING clauses only.

Does this run without error? 

If so you may have to break this out into two datasets and then do your count.

Proc Sql;
Create Table Work.Tbl_Dt_Tip_Count As
      Select
            Prep.Date
          , Prep.Name
	  From
	     (
		    Select 
			      A.Date
			    , B.Name
				, B.Code
				, B.Year
		 From 
	          Work.Want_Day A
 	  Left join
	          Ext_Data.Tbl_Date B
          
		  on  Date >= min(dt_start)
		  and Date <= Max(Dt_end)
   ) Prep
      Group by

            Date
          , Name
Quit;

If I understand correctly, I am afraid summary functions are not permitted in an on clause, and so this complicates to further nest like 

Proc Sql;
Create Table Work.Tbl_Dt_Tip_Count(drop=min max) As
      Select
            Prep.Date
          , Prep.Name
          , Count(distinct Code || name || put(Year, 8.)) As Count
	  From
	     (
		    Select 
			      A.Date
			    , B.Name
				, B.Code
				, B.Year
		 From 
	          Work.Want_Day A
 	  Left join
	          (select *,min(dt_start) as min, max(Dt_end) as max) B
          
		  on   min<=Date<=max
		 
   ) Prep
      Group by

            Date
          , Name;
Quit;
