Hi,
I want to manufacture an item from 3 item, so i have created Prod.BOM and routings and added it in item card.
But when i create a prod.order and say refresh iam getting error as " Error when calculating backward. Calender isnot available before XX-XX-XX for work centre 1
Go to the work centres in your routing, select the planning option and calendar, use the functions option to generate the dates. Depending upon your routing you may also want to set the delivery date forward to acoid the backward scheduling, but I am guessing you never set the capacity of the work centre up in the first place.
