I'm a functional newbie to ESS/MSS and would like to know how technical/functional both the packages are in terms of configuration. I understand that though ESS, employees manage their personal data and through MSS, managers can have better control over their deptt. I'm a purely functional guy so my basic question is what all is there to be configured in terms on PA/OM/BM/ECM and payroll? Somebody told me that its more of java scripting work than configuration. Points shall be awarded. Regards.
