Q: We have two different production lines with different operations. One production line works 5 days a week and the other 7 days a week. The factory calendar is assigned to the plant for 5 days a week. This calendar is checked when MRP is run. How can we assign 5 day a week and 7 days a week against a factory calendar to the related resources? Is it possible to have two types of calendars?

A: Assign factory calendars to the work centers.

Q: What is the difference between by-product and co-product and how do you differentiate them in a BOM?

A: In case of Co-product costs are settled with a apportionment structure. In case
of By-product the price of this by-product is credited to the order or the material
stock account of the lead material being manufactured.
Co-Product as well as by-product are defined as BOM Components/Items. Both of
them have negative quantities. ( Not all negative quantity items fall under these
categories!). When BOM is created for FERT , you
can see one indicator in COMPONENT DETAILS screen for co-product. You need
to define the co-products with this special indicator .
