PMS issue

Hi Experts,

We have implemented Performance management through POWL  and the workflow is as follows,

1. SAP HR admin will generate templates for the employees
2. Employee will sets Objectives/Goals from ESS
3. L1 manager will approve/reject the Objectives/Goals set by the employee from MSS
4. Employee will fill up the output/achievements corresponding to each goal
5. L1 Manager gives comments corresponding to each goals
6. L2 Review manager will review and approve the appraisal document and complete the process

But there are following issues

1. L1 should access only his own and subordinate appraisal documents under ESS, but system shows all appraisal documents which are generated by HR admin.
2. L2 Review manager cannot access appraisal document under MSS,  its coming under ESS only.
3. Valid from and to date should be as per annual financial period (i.e.01.04.2013 to 31.03.201), but system shows 2008-2009 period.

Please guide to resolve all these three issues.

Thanks and Regards,

Rashmi
