    Since SQL Server 2000 does not have the PIVOT function, you should be able to use something similar to the following:

    DECLARE @query AS NVARCHAR(4000)
    DECLARE   @rowCount as int
    DECLARE   @pivotCount as int
    DECLARE   @pivotRow as varchar(10)
    
    set @rowCount = 1
    set @pivotRow = ''
    
    create table #colsPivot
    (
      id int IDENTITY(1,1),
      name varchar(20),
      CustId int
    )
    
    insert into #colsPivot
    select 'Observacion', IDObservacionCustomer
    from yourtable
    
    set @pivotCount= (select COUNT(*) from #colsPivot) 
    
    -- reset rowcount
    set @rowCount = 1
    set @query = ''
    
    ---- create the CASE string
    while @rowCount <= @pivotCount
        begin
            set @pivotRow = (select Top 1 CustId from #colsPivot)
    
            set @query = @query + ', max(case when IDObservacionCustomer = ''' + @pivotRow + ''' then Observacion end) as ''Observacion_' + cast(@rowCount as varchar(10)) + ''''
    
            delete from #colsPivot where CustId = @pivotRow
    
            if @rowCount <= @pivotCount
                begin
                    set @rowCount = @rowCount + 1
                end
        end
    
    -- add the rest of the SQL Statement
    set @query = 'SELECT IDProspecto ' + @query + ' from yourtable group by IDProspecto'
    
    exec(@query)
