POWL for Staff

Hi Experts,

We have requirement that Staff Administrator should able to approve leave request. We would like to use POWL for this. Currently we have assigned roles as follows:

Web Dynpro Applicat. IBO_WDA_INBOX

Application Config. MANAGER_MSS_WDAC_POWL_INBOX

Problem with this role, it assigns other tasks like Working Time, Task Monitoring etc. We don't want to display these to the staffing administrator. Is there any way we can get rid of this? We just want Leave Request tab for staffing administrators.

Attached Screenshot.

Regards,

Ashish
