PM WCM Configuration

Hi Experts,

I am doing SAP PM Work clearance management Configuration. My System is ECC 6.0 EHP 5.

While doing configuration i found that options like Define Work, Define Requirements & View Profiles are not available on my development client.

I want to use these to do configuration. please suggest me how to enable these options.

Path :

SPRO > SAP reference IMG > Plant Maintenance & Customer Service > Work Clearance Management > Master Data

Ides Screenshot is attached highlighting missing options.

Thanks & Regards

Anup Lahore.
