Comment 8 for bug 453087

1. when you define any product type buy : it will not calculate method

You are completly right. I made a mistake on my explanation. It should be 1.- Define a product make to order, produce. This is right.

3. Try opening the line. You can see the field method is not shown. All fields of bill of materials are shown but not the method.

Its your personal request that you want to show the method field in form view also so you can manually open the view from following path:
administator => customization => User Interface => view
and open the form view name : mrp.bom.form.and put the method field in form view <field name="method"/>.

I made this change but method appairs not editable, so still it's not possible changing it. Sorry but my technical knowledge is really limitated.

4. This is not like sale order lines.In bom procurement method is function field which is calculated on the bases of product so when you define product in that time you have already given the procurement method so there is no need to fill it again in the bill of material form. Here it uses function field which takes reference from product.

Yes!!! This is just the reason I opened the bug. It should be like in sales order, I think. When your are defining BOM it should be possible choosing the way you wanna define procurement, even if by default it is taken from product form. First time, there is no need to fill it again in the bill of material form, but if you need doing it, there is no way.
Say that you can't have same product being part of 2 different bill of material with different procurement method, unless you don't change procurement method on product form each time before including it on bill of material.

Nevermind... I think this bug could be fixed as wishlist, instead of invalid bug. Thank you for your attention and patience:
