In SAP, there are a multitude of objects, each with their own specific role. Equipment, materials or components are all examples that can be found regularly in SAP. But what is a PRT (Production Resources and Tools)?
Unlike machines or fixed objects, PRTs are mobile elements required to perform a particular operation. Their particularity is that they can be reused several times. To give you some examples, this can represent specific tools, measuring instruments, an industrial design, etc.
Looking at these examples, we can see that there are different types of PRTs. Let's look at them together.
SAP PRT - Categories
In SAP, PRTs are divided into 4 different categories. These will influence their characteristics and use. We distinguish :

SAP PRT - Overview
It is interesting to see all the possibilities offered by the tools and for our example, we will choose a PRT of type "Material".
PRT material type - creation
The first thing to do is to choose the right type of equipment: Material type FHMI
Then, the second thing is to maintain the data in the PRT view:
- A description of your tools
- The unit of measurement of your tooling.
- Field 3 allows you to exclude or prohibit the use of this tooling on a specific Plant, for specific functions
- Here, we specify under which Task List type a PRT can be used (can it be used only in maintenance? Only in production? Everywhere?).
- These 2 fields allow you to make more precise filters in the selection screens
- With this item, we can inform how the PRT should be processed. Can it be printed, costs allocated, etc.?
- In this way, it is possible to assign a formula which will determine the amount of tooling needed for a given operation.
- The latter, in turn, will assign a formula that will calculate its use, especially for updating counters.
- Determines when the PRT will be used
- Determines when it is not needed
Setting the Grouping Key
SPRO : Plant Maintenance and Customer Service - Maintenance Plans, Work Centers, Task List and PRTs - Production Ressources/Tools - General Data - Define PRT Group Keys
Setting up the Control Key
SPRO : Plant Maintenance and Customer Service - Maintenance Plans, Work Centers, Task List and PRTs - Production Ressources/Tools - Production Ressource/Tool Assignments - Define PRT Control Keys
Here we describe in detail how the formulas work and how to use them: Formulas in SAP: tips for a successful configuration.
Material PRT - Good Receipt
Then, of course, to be able to use our tools, they have to be in stock. This is done in the same way as any other material. So you can carry out the MIGO transaction.
Material PRT - Assignment
Now that our items are in stock, let's choose when they will be useful in our process. For SAP, a production resource/tool is used to perform a specific operation. Therefore, it can be assigned in 2 ways:
It can be assigned either in the maintenance module or in the production module. The principle being similar, we will focus together on an example in production.
Let's go into the production Routing
After choosing the operation in question, let's place the PRT.
PRT - Availability check
When material is assigned to an OF, it is possible to check its availability for carrying out the operation, and therefore the OF. The check is carried out :
In case of non-availability, it is then possible to validate the process or to stop it manually, or to carry out this action automatically. The control can be carried out on 2 distinct parameters:
All this is set in the customizing :
SPRO : Plant Maintenance and Customer Service - Maintenance and Service Processing - Maintenance and Service Orders - Functions and Settings for order Types - Availability Check for Material, PRTs, and Capacities - Define Inspection Control
The availability check is then assigned to a particular order type.
- Indicates when the control is carried out. Here, it is triggered at the creation of the OF
- This check box activates or not the availability control for the PRT
- Specify how this control will be carried out (on the basis of status only? Also on the quantity in stock?)
- What happens if the RTP is missing? Is it automatically blocking? Does the user have a choice?
PRT - Status
It is possible to change the status of a tool to prevent its use (in case of breakdown, etc.).
This change is accessible in the Material Master Data, in the Header section.
Finally, once the button has been activated, a padlock appears next to the material:
SAP PRT - Conclusion
Last but not least, the use of tooling / PRT enables greater finesse in the creation of operations, both in maintenance and in production.
What's more, it also lets you assign components that can be reused several times. Coupled with other features such as :
In conclusion, it is possible to be highly efficient and adaptable to most company processes.
