HI All,

I am working in ax 2012 employee master data import through .net.

While i am doing this i am facing the following error.

Document Worker could not be created. Error details: Cannot create a record in Locations (LogisticsLocation). Location ID: 000000095, EmployeeAddr.

The record already exists.

Can any one help me to solve this issue, your help highly appreciated here.
