What I need is the inventory section. See we sell electrical components.
Some we sell separately and others we combine parts.
The inventory does not allow the assembly of parts to sell. So when
we sell a assembled part vtiger needs to calculate and then subtraction of those parts from inventory.
So example: I sell computers. I can sell the motherboard, power supply, hardrive, or cables seperately but also I can sell the complete computer systme complete or as an assembled or combined
Then vtiger has to calculate the cost of the combined final part and be able to do a roport on cost vrs sell of that final part.
