Query a stored procedure that exec's a dynamic query. Error Linked server indicates object has no columns

Question

I have a stored procedure that dynamically creates a pivot query.  The procedure works and returns the correct data.  Now I have a requirement to show this data in reporting system that can only pull from a table or view.  Since you can not
create a dynamic query in a view I tried to do a select from using openquery. 
Example 'Select * from OpenQuery([MyServername], 'Exec Instance.Schema.StoredProcedure')
I get the error back "the linked server indicates the object has no columns".  I assume this is because of the first select statement that is stuffing the variable with column names. 
CODE FROM PROCEDURE
Alter PROCEDURE [dbo].[Procedure1]
AS
BEGIN
SET NOCOUNT ON
Declare @cols nvarchar(2000),
  @Tcols nvarchar(2000),
  @Sql nvarchar (max)
select @cols = stuff ((
      Select distinct '], ['+ModelName + '  ' + CombustorName
       from CombustorFuel cf
       join Model m on cf.modelid = m.modelid
       join Combustors cb on cf.CombustorID = cb.CombustorID
       where cf.CombustorID > 0
       for XML Path('')
      ),1,2,'')+']'
Set @Tcols = replace(@Cols, ']', '] int')
--Print @Tcols   
--Print @Cols
Set @Sql = 'Select GasLiquid, FuelType, '+ @Cols +'
from
 Select GasLiquid, FuelType, ModelName+ ''  '' +CombustorName ModelCombustor, CombFuelStatus+''- ''+CombFuelNote CombFuelStatusNote
  from Frames f
  join Family fa on f.Frameid = fa.frameid
  join Model m on fa.FamilyID = m.FamilyID
  join CombustorFuel cf on m.Modelid = cf.modelid
  Join Combustors c on cf.CombustorId = c.CombustorID
  join FuelTypes ft on cf.FuelTypeID = ft.FuelTypeID
  where cf.CombustorFuelID > 0
    and CombustorName <> ''''
 ) up
Pivot
 (max(CombFuelStatusNote) for ModelCombustor in ('+ @Cols +')) as pvt
order by FuelType'
exec (@Sql)

Answer 1

Then again, a good reporting tool should be able to do dynamic pivot on its own, because dynamic pivoting is a presentation feature.

Displaying and reading are two very different things.
#1) SSRS Needs a fixed field list on the input side to know what what to make available in the designer.
#2) SSRS cant read "exec (@Sql)" out of a proc, even if there is a fixed number of columns (at
least it can't use it to auto build the field list from the proc)
I use dynamic SQL in my report procs on a fairly regular basis and I've found it easiest to simply dump
the results of my dynamic sql into a temp table at the end of the procs and then select from the temp table.
Basically, Erland is correct. Stop trying to pivot in the query and let SSRS (or whatever reporting software you're using) handle it with a Martix.
