What must be set for capacity availability checks on production orders to occur?

For capacity availability checks on production orders to function correctly, it is essential that the indicator relevant for finite scheduling is activated. Finite scheduling involves recognizing resource constraints and ensuring that no more work is scheduled than can be handled by the available capacity. This indicator allows the system to take into account the actual workload and availability of resources when planning production activities.

When this setting is enabled, the system can perform the necessary calculations to determine if there is enough capacity on the resources to execute the production order within the defined timeframes. This helps in identifying potential bottlenecks in production and allows for more effective planning and scheduling.

While other options such as having a checking rule and group assigned, performing PRT availability checks, or having a checking control assigned in customizing can be important for different types of checks and planning processes, they do not specifically relate to ensuring that finite capacity checks are correctly implemented. Hence, having the finite scheduling indicator set is the key requirement to facilitate accurate capacity availability checks on production orders.
