HR_MAINTAIN_MASTERDATA in standard service not able to lock employee
I am using PZ13 transaction to update personal information. This seems like some magic. I was able to save changes earliar. but not when i use any of ESS service Address pz02, bank etc. It is not able to lock employees.
Error is: EPG 184 Employee/applicant is not locked yet
I am able to change master data from PA30 screens.
Is there any customizing or pre-requisite for locking employee data.
Thanks for your time,
