SQL Server Error Description for the Code :35346

SPLIT clause of ALTER PARTITION statement failed because the partition is not empty.  Only empty partitions can be split in when a columnstore index exists on the table. Consider an ALTER TABLE SWITCH operation from one of the nonempty partitions on the source table to a temporary staging table and then re-attempt the ALTER PARTITION SPLIT operation. Once completed, use ALTER TABLE SWITCH to move the staging table partition back to the original source table.
