Maintenance Planning for Production Resources/Tools

Use

If you use production resources/tools (PRT) that have an equipment master record, you can:

Plan and monitor the wear and tear of the PRT

Create a maintenance plan that relates to the degree of wear and tear

You can thus plan preventive maintenance measures sensibly. The current degree of wear and tear is taken into account during PRT availability checks in production orders, maintenance orders, and networks.

Features

You create the following information for the maintenance planning of PRTs:

A PRT usage counter that provides information on the degree of wear and tear for a PRT

The wear and tear to be expected for each process step (operation or phase)

An activity-related maintenance plan

PRT Usage Counter

In plant maintenance, you create a usage counter for the PRT. You assign the counter a characteristic whose unit is suitable for measuring PRT wear and tear. You enter the counter as a measuring point in the equipment master record of the PRT.

You determine the initial counter level by creating the number of available units in a measurement document. When you confirm a production order, maintenance order, or network, the system creates a corresponding measurement document for the relevant PRT, that is, it automatically updates the counter level.

As PRTs cannot be used in process orders and process order confirmation at the moment, the PRT usage counter cannot be updated automatically in production planning for process industries (PP-PI). If required, you must create measurement documents manually.

Expected Wear and Tear

You determine the expected wear and tear during the assignment of PRTs to recipes/task lists by entering the following data:

A usage value that specifies the expected wear and tear for the base quantity of the material to be produced

The usage value must have the same unit as the PRT usage counter.

A formula that the system can use to calculate the total usage value for the order, that is, the expected wear and tear for the order quantity

The system also uses this formula to calculate the actual wear and tear from the confirmed yield during confirmation. The PRT usage counter is updated with the values that have been calculated in such a manner (see PRT Usage Counter above).

As PRTs cannot be used in process orders and process order confirmation at the moment, the usage value and formula do not have any functional significance in PP-PI.

Maintenance Plan

You define a maintenance plan to ensure that PRTs are regularly serviced. In the maintenance plan you lay down which tasks are carried out at which counter level. You enter this maintenance plan in the PRT equipment master record.

Creating a Maintenance Plan

When you maintain a PRT with an equipment master record, you allocate the counter and maintenance plan on the PRT data tab page in the Plant maintenance default values section (see Creating PRTs as Equipment).

You enter the data on a PRT's usage value, on he General View screen when you assign PRTs in recipes/task lists (see Assigning PRTs to Operations/Phases).
