The optional Retirement Group column is used to identify a group of resources that must be considered together for retirement and retired on the same date. If a resource in the group is not eligible for retirement in a given study, then the rest of the group is considered without it.
The column accepts a user-defined string value (akin to an ID), such that all resources with that string are grouped. Only one group assignment is allowed per resource.
NOTE: This column requires the MIP method for Long Term studies, and will not be used with Traditional method.
