    Abhijeet,

    Yes you are right if a materail is coproduct, you need to activate the coproduct check box in material master MRP2 view. Also in the BOM you need to define this material in -ve quantity. For coproducts we also need to define the apportionate structure with equivalence number for costing purpose, this will be done in "Joint Production" details in the same view.

    Biproduct has only the -ve quantity in BOM component, it does not go for joint production costing.

    Hope this helps....Reward your points,

    Regards,

    Prasobh

      Abhijeet,

      If Petrol & Diesel is produced from different process then yes, if not a single BOM. As described by me except "Crude Oil" and "Water" remaining all materails needs to be defined as Coproducts.

      Hope this clarifiys, Reward your points and close the thread.

    Hi Abhijeet,

    The below thread was posted earlier and below is the one of good explainiantion to understand the functionality between co-product and by-product.

    By product is the product which will be creaed while making production

    you have to maintain the setting in BOM with negative quantity (-). Then system automatically will pick this as by prodcut.

    movement type 531 to post the by-product during confirmation. Settlement of cost will be done to the header of material.

    Co product is the product

    You have to activate check box in MRP2 view for co product.

    Co-Products

    Use

    Products that are usually manufactured together can be produced using one production order.

    The main product is the primary reason for the production process. It is displayed in the production order header. The system also creates a separate order item for the main product.

    A co-product is a product that is produced in conjunction with other products. The system creates a separate order item in the production order for each co-product. As a result, it is possible to display actual costs at co-product level.

    A by-product is a product that is produced in conjunction with other products. The system does not create a separate order item for each by-product. The material valuation of a by-product is always based on the price specified by price control in the material master.

    Creating a production order to manufacture co-products has the following advantages:

    Main product and co-product(s) are settled to different receivers

    Goods movements can be posted simultaneously for all products manufactured in the order

    The following prerequisites must be fulfilled if you want to create a production order with co-products or by-products.

    Prerequisite for the main product:

    The indicator Co-product must be activated in the material master of the main product (MRP area)

    Prerequisites for a co-product:

    The indicator Co-product must be activated in the material master of the co-product (MRP area)

    The co-product must be listed as an item in the bill of material of the main product

    On the Basic data tab page of the BOM item, the indicator Co-product must be activated in the field group General data.

    Prerequisites for a by-product:

    The by-product must be listed as an item in the bill of material of the main product

    The bill of material item must have a negative quantity (for example ‘1 -’).

    Regards
