  Hi everyone,
  
  I think I have a bug in 6.0.3 stable with the product cost structure
  report in the product (should have mrp module installed). I have the bug
  with the report but I think the problem comes from the way the BOM is
  computed.
  
  Let's take the following BOM :
  
- 
-                                                                     |-- 2 Product N
-                                                                     |
-                               |-- 3 Product A------| -- 1 Product M
-                               |                                     |
-                               |                                     |-- 1 Product O
- Product X ------|
-                               |-- 2 Product B
+                                 |-- 2 Product N
+                                 |
+            |-- 3 Product A------|-- 1 Product M
+            |                    |
+            |                    |-- 1 Product O
+ Product X -|
+            |-- 2 Product B
  
  And this is the product cost structure I get :
  2 Product N
  1 Product M
  1 Product O
  2 Product B
  
  It doesn't take at all account of the 3 Product A required! I should have :
  2*3 = 6 Product N
  1*3 = 3 Product M
  1*3 = 3 Product O
  2 Product B
  
  I have the same result when I check the "Product BOM Structure" so I really think this is a bug who come from the way the structure is computed.
  Of course with this bug, the cost structure is completely wrong and unreliable.
  
  What do you think about it?
