Assigning PRTs to an Operation 
You can assign different PRTs (production resources/tools) to the same operation, and also assign the same PRT to different operations.
1. Call up the required order in create or change mode.
2. Enter all the required data and choose the operation overview.
3. Select the operations to which you want to assign PRTs.
4. Choose PRT (production resource/tool).
The system processes the operations you have selected one after another. The following cases can arise:
The Change Order: PRT New Entries dialog box appears.
If you want to add another type of PRT, choose Equipment, Others or Document.
The Change Order: PRT List for Operation dialog box appears.
If you want to assign additional PRTs, choose Edit
The system writes the PRT to the PRT List for Operation and the dialog box PRT New Entries reappears ready for input. You can now assign another type of PRT.
The PRT List for Operation screen appears with all of the production resources/tools which you have assigned.
