If you have created a production resource/tool as a piece of equipment, you can use a status to specify whether the PRT is:
Released for use
This status is useful if the PRT is freely available for use.
Not released for use
This status is useful if, for example, there is no longer a work list available for the PRT or the PRT is defect.
Select the master record of the PRT in the Create or Change mode.
Choose the PRT data screen of the master record.
On the PRT data screen, choose
Save the equipment master record.
