When creating or changing a production resource/tool (PRT), you can determine whether it is freely available by using the corresponding status. You can thus temporarily lock a PRT, for example, because it is defective. The status is taken into account when you:

• Assign PRTs to operations or phases in recipes/task lists, production orders, or maintenance orders

• Check the PRT availability in the production order, maintenance order, or network

How and why you release an individual PRT, depends on the PRT category.

• For materials, equipment, and documents, you determine whether they can be used as a PRT by setting the status.

• The system also performs a static inventory audit, that is, it checks whether a sufficient quantity is available at the present time

• The system also checks the PRT usage counter for equipment

• For production resources/tools with a PRT master record (miscellaneous), you use the status to determine specially:

• Whether the PRT can be assigned in resource planning, that is, in recipes/task lists and orders
• Whether the PRT is available for production and consequently whether availability checks are permissible in the order
