Tables object (TMSL)
Applies to: 
SQL Server 2016 and later Analysis Services

Fabric/Power BI Premium
Defines the tables contained in a model. Tables in a model are either bound to tables in an external database from which data is imported or queried, or a calculated table constructed from a DAX expression. Within a table, one or more Partition objects describe the source of the data. Between tables, a Relationship object specifies the cardinality, filter direction, and other properties of the relationship.
Object Definition
All objects have a common set of properties, including name, type, description, a properties collection, and annotations. Table objects also have the following properties.
dataCategory
Specifies the type of Table, usually left unspecified. Valid values include 0 - UNKNOWN, 1 - TIME, 2 - MEASURE, 3 - OTHER, 5 - QUANTITATIVE, 6- ACCOUNTS, 7 - CUSTOMERS, 8- PRODUCTS, 9 - SCENARIO, 10- UTILITY, 11 - CURRENCY, 12 - RATES, 13 - CHANNEL, 4 - PROMOTION, 15 - ORGANIZATION, 16 - BILL OF MATERIALS, 17 – GEOGRAPHY.
isHidden
A Boolean that indicates whether the table is treated as hidden by client visualization tools.
True if the Table is treated as hidden; otherwise false.
columns
Represents a column in a Table. It is a child of a Table object. Each column has a number of properties defined on it that influence how client applications visualize the data in the column.
measures
Represents a value that is calculated based on an expression. It is a child of a Table object.
hierarchies
Represents a collection of levels that provide a logical hierarchical drilldown path for client applications. It is a child of a Table object.
Usage
Table objects are used in Alter command (TMSL), Create command (TMSL), CreateOrReplace command (TMSL), Delete command (TMSL), Refresh command (TMSL), and MergePartitions command (TMSL).
When creating, replacing, or altering a table object, specify all read-write properties of the object definition. Omission of a read-write property is considered a deletion.
Condensed Syntax
Table object definitions are complex. This syntax collapses interior properties and objects to give you a high-level look at the main parts.
