Bug 182296 Crosstab - non-numeric measures
Feature request. Looking at the 2.2.M6 release, it seems that measures (the fields that can be in the matrix part of the output) need to be numeric. I looked at the spec documents and it seems there is no requirement for non-numeric measures
data/org.eclipse.birt.data/src/org/eclipse/birt/data/engine/olap/data/impl/dimension/Hierarchy.java
documentObj.writeInt( iterator.getFieldType( attributes[j] ) );
			}
		}
		else
		{
			documentObj.writeInt( 0 );
		}
	}
