SYMPTOM:
When executing a report containing an attribute element prompt in Web 9.x, the first few windows of prompt answers are populated as expected:
Window 1:

Window 2:

However, where answers have been selected from these windows, subsequent sets of prompt answers may appear as blank:

This issue persists regardless of the incremental fetch setting in Web:

Modifying the limit set in the Intelligence Server Configuration for element caches may result in different sets of prompt answers being affected by this issue:

CAUSE:
One possible cause of this behaviour when executing a prompted report using incremental fetch in Web may be the use of an uncertified ODBC driver for connecting to the warehouse.
ACTION:
This may be rectified by creating a DSN to the warehouse via the Strategy Connectivity Wizard, to ensure that the certified driver, as shipped with the product, is used.
