To compute phase numbers for order-based planningLN computes a phase number for each plan item. LN bases the phase number for order-based planning on the following data: Criteria for phase numbers The phase numbers of the plan units must conform to the following criteria:
Note An item is controlled by central multicompany planning if the Central Multicompany Planning check box in the Items - Planning (cprpd1100m000) session is selected. Moreover, there must be a central multicompany scenario that includes the companies involved. If you use the Compute Phase Numbers (cprpd6200m000) session to recompute phase numbers for central multicompany planning, you need to specify the multicompany scenario involved. Computation procedure The computation of the phase numbers is an iterative process. You can choose between two methods:
In a regenerative computation, every plan item initially gets phase number 0. LN then checks the plan items one by one and adjusts their phase numbers until the criteria for phase numbers are fully met. For information on the net-change computation see Net-change phase number computation. You can see the result of the computation in the Order Phase Number field in the Items - Planning (cprpd1100m000) session. Note The phase number computation also checks for cycles in the bills of materials.
