When trying to delete records of the LiteSpeed Central database using the LiteSpeed_DeleteActivity store procedure like this:
exec [LiteSpeedCentral]..[LiteSpeed_DeleteActivity] @delCentral=1, @purgeDeleted=1, @delLogshipping=1, @delStatus=1, @delUnit=3, @delUnitType='MONTHS'
Even with different parameters, is completed instantly without deleting any records. This can also happen with the LiteSpeedLocal database.
