Create a Location Alias
Create a location alias if you need addressability to another Essbase cube for your block storage (BSO) calculations or formulas. Location alises help you call @XREF or @XWRITE functions to reference data from another cube, whether that cube is on the same Essbase instance or a different one.
You do not need to provide a user name and password when you create a location alias using the Essbase web interface. However, if the remote cube is not on the same Essbase instance, a saved connection is required (refer to Define a Reusable Connection for Partitions or Location Aliases if you need to create one).
