1.3.6 Common Data Elements

Common data elements are generally data elements that
have a common definition across database Information Areas
or across files within an Information Area.  Common data
elements are used as the key data elements for sorting and
summarization processes as well as their general use with
SAS PROCs through the BY facility.

Common Data Elements, unlike the standard data elements,
do not have a data element prefix, as was described in
section 1.3.1.4, CA MICS Data Element Label Conventions.
Instead, they have a mnemonic label, which is defined
identically in each File in which they may appear.

The core set of CA MICS Platform common elements is listed,
along with definitions, in Appendix A.2 of this guide.  See
the individual product guides for common elements associated
with each product.
