Production Resources/Tools
Definition
Production resources/tools (PRTs) are the capacities you require to perform an operation at a certain work center. In contrast to machines and technical devices, PRTs are mobile, in other words they are not fixed to a specified location.
Production resources/tools include, for example,
Use
If you plan work processes in maintenance task lists and at the time of planning know which resources are required to perform the operations, you can enter these resources in the task list.
Structure
The PM application component has the following four categories of master records for production resources/tools (PRTs):
If you create a PRT as a material, you can use all the functions available for a material master record. The system supports the procurement of this PRT category. In other words, this PRT category can be both externally procured and internally produced. Both quantity- and value-based inventory management can be used for this PRT category.
When you create a simple production resources/tools master record, the system does not support procurement of this PRT category, and inventory management is not possible. The advantage of the PRT category "PRT master (other)" is that little data maintenance is required for this master record.
When you create a document master record for a PRT, you can manage it as a document in the R/3 system. A document is a data storage medium that either contains information for the user or is used to transfer data from one system to another. A document, for example, can contain an overview of all the pieces of equipment requiring maintenance.
When you create a PRT as a piece of equipment, you can use all the functions available for equipment master records. It is useful for PRTs that have to be individually maintained and/or maintained at regular intervals, and which require proof of the maintenance tasks performed and/or operating times.
