  OnBeforePrint of each page:
  
  page1.visible := (UserVariable = 'user1') or (UserVariable = 'user2')
  
  Check how to pass values to variables in the manual or in the other threads of the forum here

  But i'm talking about maybe 100000 users, not only 2. All the information comes from a table or a query.

  Just cycle through the dataset(s) in the correct sequence.
  The easiets may be to have a query for the users and another one for the data on the 3 pages. However, this may be quite slow.
  
  What is the real problem here? That it does not work at all, or that it takes too long?

  The problem is that in this way, I'll have for each user the page one, and after for each user the page 2, and so on:
  (User1-Page1) (User2-Page1) (User3-Page1) (User4-Page1)....(User1-Page2) (User2-Page2).... <--This's not what i need
  (User1-Page1) (User1-Page2) (User1-Page3) (User2-Page1)(User2-Page2) (User2-Page3) (User3-Page1) .... <--That is
  I need to have the information grouped by customer, composed by 3 diferents pages.

  Still, what you need is to control if the page is printed or not, and this is how it's done:
  
  Page1.OnBeforePrint(sender);
  begin
  page1.visible := yourcondition. This can be a function call, back to your Delphi code or FRscript. Read the manual for this
  end;

  Does this mean you have a single report with the 3 pages?
  My methods would use 4 queries, an outer one for the user, and 3 nested inner ones for the 3 pages, and there would be 3 reports.
  
  while not customer_query.EOF do
  begin
  report_query_page1;
  print_page1;
  report_query_page2;
  print_page2;
  report_query_page3;
  print_page3;
  customer_query.next;
  end;
  
  Never having used a FR report with multiple pages (just subreports) there may be other ways of printing.
  
  This method is not the most efficient and may be slow. 3 queries have to be run and 3 report have to be rendered for each customer. However, depending on the database used for storage some careful indexing might improve the data access time.
