What is payroll lock?

Each month certain functions under the Self-Service portal are locked for a couple of days to enable payroll processing. While the payroll lock is in effect, some ESS/MSS functions have limited availability to prevent changes from negatively affecting the payroll process.  Likewise, HR Partners are not able to take certain actions during payroll lock for staff members in the ERP Central Component  (ECC) system.


Please note that payroll lock occurs monthly and the dates when ESS/MSS have limited functionality are communicated via email broadcast to staff at UNHQ, Peacekeeping Missions, and Office Away From Headquarters.  Users regain full ESS/MSS access as soon as the monthly payroll process has been completed.

Important to Note! Effective June 2019, staff and managers can take leave-related actions in Umoja Self-Service at any time for all absence and attendance types. While leaves can be requested and approved during the payroll lock, balances will be updated after the payroll lock period. For maternity leave, there is no change. During payroll lock, staff and managers can continue to request and approve maternity leaves that will be taken after the current payroll month.
