What is Skipcheck in TM1?

Skipcheck in TM1 forces the TM1 engine to “skip the checking” of empty cells in a cube. So if you had 30 days in a month and data in only 9 of them, only 9 cells would be aggregated to get the total for the month. With the the skipping of blank cells disabled, all 30 cells would be checked to get the month total – three times more inefficient. … Continue Reading
