Tool Life Monitoring for PRT assigned in routing

Hi experts

I have created a PRT and assigned it in the routing operation.

I have given the total life of the PRT in Master Data of PRT (eg. Life 500 EA - 500 times i can use the PRT)

I am not able to see the count (ie. how many times currently it is used?)

When the life time is completed system should give message.

Please guide me to get it.

Thanks & Regards

Bala
