Within SAS Information Map Studio, if you define a calculated measure
using data items in its expression, then the calculated measure will not
show up in SAS Enterprise Guide and the SAS Add-In for Microsoft Office.

Another reason that you might not see a calculated measure is when an
aggregation is defined in the measure. The Information Map Libname
Engine (IMLE) does not support aggregations. The Information Map libname
engine is used to display information maps in SAS Enterprise Guide and
the SAS Add-In for Microsoft Office.

One workaround for expressions that do not use aggregation functions is to 
create the measure in SAS Information Map Studio
using physical data columns in its expression. When you create the measure in SAS
Information Map Studio, on the Definition tab in the Data Item
Properties dialog box, select the button labeled Edit... In the
Expression Editor that opens, select the Data Sources tab. Under the
Data Elements tab, there is a tree structure that shows a Business Data
node and a Physical Data node. This is where you should always choose
columns from the Physical Data node.
