| # Capacity CTP Capacity CTP refers to information on the available resource capacity. This information can be used for order promising. Capacity CTP can be expressed in two ways: The capacity CTP of a resource: the free capacity at a resource that is still available for additional production, up to and including a certain plan period. The capacity CTP of a plan item: the item quantity that can be produced based on the capacity CTP of a resource, or the capacity CTP of all resources that are critical in CTP. A capacity CTP check is based on the capacity CTP at a set of critical resources. When a customer order is received, a CTP check can be carried out on the resources' availability. As a rule, a capacity CTP check is carried out in the following situation: The ATP of an item is checked. The item's ATP is insufficient to cover the demand involved. Capacity CTP checks are enabled for the item involved: you selected the Capacity CTP check box in the Items - Planning (cprpd1100m000) session. Note A full multilevel CTP check can also involve capacity CTP checks at lower (component) levels. This depends on whether or not you selected the Critical in CTP check box in the Items - Planning (cprpd1100m000) session for the for the (component) item involved. Note To do a capacity CTP check for an item, that item does not need an item master plan. However, only resources that have a resource master plan is taken into account. How to set up capacity CTP checks Carry out the following steps to set up capacity CTP checks: Select the Capacity CTP check box in the Items - Planning (cprpd1100m000) session for the involved item. Select the Critical in CTP check box in the Resource (cprpd2100m000) session for the resources in the bill of critical capacities (BCC) that ERP Enterprise must take into account for capacity CTP checks. To disable the capacity CTP check during the execution of a particular check, clear the Capacity check box in the ATP Handling (tdsls4899m000) session.
