This topic describes how the WUI can issue warnings if the expected number of records to be returned in certain views exceeds a set threshold.
This new feature is designed to issue a warning if a request to open certain views will result in a larger than expected amount of data. This provides an opportunity to alter the filters on these views and confirm or cancel the request before the request is executed.

A value set in a user group takes precedence over a value set in the DEFAULTWARNCNT parameter. Before a warning is issued the WUI checks to determine whether or not the signed on user is associated with a user group (this can occur only if the WUI is running with security switched on). If so, the WUI uses any value for the warning count specified in that user group. If the user does not belong to a user group, or no maximum value is set, the WUI checks the initialization parameters and uses any value set there. If no value has been specified, the default of 0 is used.
Clicking Refresh drives a new request. This allows you to alter the primary key field, which is included in the Warning count screen, to test a new filter value in order to produce a smaller set of results. Any other filters remain in place from the original request. If the set of results returned is not below the warning count limit, the warning count screen is redisplayed with the original warning count message. If the size is below the warning count limit, the warning count screen is redisplayed.
Clicking OK at the bottom of the screen performs the current request regardless of the number of results to be returned.
Clicking Cancel is the equivalent of pressing the back link on the browser; the previous screen is redisplayed.
