I guess you already created the cost categories. But have you created the manufacturing charge items (could be other charge, service item, etc.)? LAB00025 is a manufacturing charge item assigned with a default “purchase price” of 25/hr. You have to specifically tick the manufacturing charge item box, link it to the corresponding cost category, and assign the default rate per hour at the minimum. The item is also limited to one subsidiary only (so you have to create multiple versions of them in case multiple subsidiaries need it).
