The frequency of updates is controled via the Dimension or Cube screens in CoreBUILD. Updating dimensions daily will cause no issues, it will check the source each night and update the lists to reflect any new elements. Updating cubes Daily could cause issues though, the data volumes associated with monthly snapshot data can cause issues when loaded 30 times a month. It is suggested that should daily data be required the data volume be reduced as to not cause issues. A cube could also be loaded daily over a number of days while the source is finalised and then later cleaned up to remove those load dates not being used.
