In the network header, select the menu options Edit -> Availability -> Capacity.

With Release 3.0E you can now have the system perform the capacity availability check automatically when you set the status created or released in a network. Make sure that the indicator No check is not set in Customizing for the Project System under step Maintain control parameters for availability check.

If you have not created your own overall profile in Customizing, the system will use the overall profile SAPSFCG013 for the capacity availability check. The period splits are week in this profile.

When a network cannot be carried out because there is not enough capacity, you can reschedule the dates for the network activity using finite scheduling. The capacity requirements of other networks, orders operations or activities on one work center within a planning period (basic load) is all taken into consideration in the capacity availability check. Before you check your networks for available capacity, you should first determine the basic load. To do this, carry out report RCCYLOAD to determine the basic load. Create basic load
