21.2.4 Assigning Sources a Data Loop Name

Set each report source’s Data Loop Name to match the short name used in the template tags.

In each report source, use the Data Loop Name setting to assign the short name you used in your layout document tags. The setting name echoes its purpose. It's the name you use in a tag to "loop over" each row of data in the report source. For example, it's set to dep for the Department report source below. Recall that the Excel spreadsheet referenced this Data Loop short name and lowercase column names from this query with the syntax:
{#dep}Department {dname} ({deptno}) in {loc}{/dep}
