When you view details, one of the following root causes will likely display:

This error can appear for promoted reports and for new reports if the multi-edit feature is used to change data item properties in the information map.

As a workaround, follow these steps:

1. In SAS Information Map Studio, open the information map.
2. Open the properties for each data item. Do not use the multi-edit feature.
• For measures, and make sure that the Default aggregate function has a value.
• For categories, make sure that COUNT(argument) is displayed (but grayed-out) in the Default aggregate function list.



If it is not, then select the Measure radio button and then switch back to Category. COUNT(argument) should now be filled in.



3. Save the information map.

Change in behavior from release 3.1

The behavior in SAS Web Report Studio 3.1 is different, which means that reports that rendered correctly in 3.1 might not render after promotion. SAS Web Report Studio 3.1 does not fail if the default aggregation method is not filled in.
