Bug 190419 The topn filter doesn't take effect on the datetime type dimension[1102]
Description: The topn filter doesn't take effect on the datetime type dimension[1102] Build number: 2.2.0.v20070601-1347 Steps to reproduce: 1, New a crosstab which includes datetime type dimension 2, Specify a filter on the year level using two filter condition data["year"] topn 2 or dimension["Date"]["year"] topn 2 3, Preview Expected result: Both filter condition can take effect Actual result: No effect only 2005 year in crosstab
