There are many threads available about PRT Availability check.
Please search with term "PRT Availability Check".
In addition, PRT availability check has not been designed well in current SAP to match your requirement. So you may need to go for some work around (like creating PRT as Material & doing issue for the operations and once operation is completed, PRT Material should be reversed with 262 movement back to stock) or through development.
