When you capture or retrieve grid-based data, the program uses a default “include” logic that assumes you want to include all of the data you captured or retrieved. This logic remains, even when you specify to exclude records or fields, insert record or fields, or edit records.
However, when you select any “include” option from the first Add Filter Rule drop-down list, the default “include all” no longer applies, and you must explicitly specify the records to include.
Therefore, to hide records or fields from the display, first use Include Records to specify the records to include, then use Include Hidden * to specify the record or field to hide.
WARNING! If you select Include Hidden Records without explicitly specifying the records to include, the final preview of the portlet is blank. Because you have not explicitly stated which rows of data to include, the only data that is actually there is hidden, resulting in a blank display.
