Purpose
Expands a column having a PERIOD data type, creating a regular time series of rows based on the period value in the input row.
The expansion of a PERIOD column produces one value-equivalent row for each of the time granules in the epoch or timestamp representation of the specified time granule.
You can perform time series expansions only on PERIOD expressions which can be regular period expressions or derived period columns.
