The Error/Warning Messages topic allows you to select the census data-type error/warning conditions that should be executed when you process a calculation.  While the Errors/Warnings Library may contain both census data- and benefits-based error/warning definitions, only the census data-based ones, identified as Type "DATA" in the first column of the list view, may be selected here.

There are three columns in the list view box, and clicking on the column's header will sort the view by that column's values.  The first column contains the Type of error/warning message, but this list only contains library entries of the type "DATA."  The second column contains the Name of the library entry, and the third column contains the date that it was last Modified.

To create a new Error/Warning library entry and include it in the Census Specifications, click the New button. To edit an existing entry or to omit it from the Census Specifications, double-click the library entry or select the entry and click the Edit button. To include or exclude existing Error/Warning library entries, click the Add/Omit button. 

The Add/Omit Errors/Warnings dialog box displays all of the Error/Warning library entries that have been classified as data checks in the Errors/Warnings Library. Any entry with a check preceding it will be processed. Library entries may be checked or unchecked individually, or the   icons at the bottom of the dialog may be used to check all entries, uncheck all entries, or toggle (check/uncheck) entries. There are four columns on the dialog.  The first column sorts based on the items selected. The second column sorts the list by Type, but this list only contains DATA type entries.  The third column sorts the list alphabetically by Name. The forth column sorts the list by the last date the entry was Modified.
