This topic describes how to delete a column from a tabular model table.
Delete a Model Table Column
Deleting a column from a model table does not delete the column from a partition query definition. If the column you are deleting is part of a partition, you must manually delete the column from the partition query definition. Failure to delete the column from the partition query definition will cause the column to be queried and data returned, but not populated to the model table, during processing operations. For more information, see Partitions (SSAS Tabular).
