Hello Amit,

I must agree with Lionel  - it is very normal practice to have many of
the same components within one BOM.

I also have also the same issue for a customer of mine - in the textile
industry.

Let me explain:

I'm trying to set-up a 'master' BOM containing many sub-components -
consisting of cotton threads.  Many of these sub-component (threads) are
referencing the same core product -  but with slightly varying
quantities per meter.  i.e. each threads is the same raw-material, same
costs per meter, etc. - just different length (due to the patterns the
weaving machines are creating).

When trying to add multiple threads directly to the BOM - I also get
this error message "ValidateError - Error occurred while validating the
field(s) product_id: BoM line product should not be same as BoM product"

 
Work-around:
One work-around I found that work (well sort-of) -....
  
a) first create a BOM without any components, but  ensure all workcentres and other information has been added.  
b) Then create the BOM components with reference to the same products  (but with different quantities) and also referencing Parent BOM (in the properties/parent BOM field) .  
c) When complete you can open the parent BOM again and see the multiple sub-components have been added. 

As I needed an exact sequence of material on the BOM this seems the only
way I could  create the master BOM.

Nevertheless,   the main issue with this work-around is you can't change
anything on the master BOM again - without getting the error message :

"ValidateError - Error occurred while validating the field(s)
product_id: BoM line product should not be same as BoM product"


The error message in this case  is also misleading as the final product (Master BOM) is not included anywhere in the BOM component list - so there is no issues with recursive errors of the same product on this BOM. I only have many repeating items in a BOM - but with varying quantities.  


As you can imagine this is really irritating when you have over 10.000's products.   So  please reconsider a solution for these type of business scenarios.

Thanks

Colin

Title:
  MRP : check_product very strict - BoM line product should not be same
  as BoM product.

Status in OpenERP Addons (modules):
  Confirmed

Bug description:
  In openerp 6.1 on module MRP, there are a function to check product on BoM.
  BoM can't contained two lines or sublines with same product.

  For example, we have a bom (bomA) with two bom composent, I named it bcomp1 and bcomp2 . 
  bcomp1 and bcomp2 contain a line with same product, product1 and parent bom is bomA.
  With check_product constraint, there are a problem on bomA.

  We work in electronic. bcomp1 and bcomp2 are bom of an electronic card
  and they used same LED (product1).

  Why this hard check and not checked products only on BoM and checked
  products of bom composent without memorised products of parent BoM ?
