Manually Process Data (SSAS Tabular)


This topic describes how to manually process workspace data in SQL Server Data Tools (SSDT).

When you author a tabular model that uses external data, you can manually refresh the data by using the Process command. You can process a single table, all tables in the model, or one or more partitions. Whenever you process data, you may also need to recalculate data. Processing data means getting the latest data from external sources. Recalculating means updating the result of any formula that uses the data.

Sections in this topic:

To process data for a single table or all tables in a model

  1. In the model designer, click the table you want to process.

  2. Click on the Model menu, then click Process, and then click Process or Process All.

To process data for all tables using the same connection

  1. In SQL Server Data Tools, click on the Model menu, and then click Existing Connections.

  2. In the Existing Connections dialog box, select a connection, and then click Process.

To process data for one or more partitions

  1. In SQL Server Data Tools, click the Model menu, then point to Process, and then click Process Partitions.

  2. In the Process Partitions dialog box, in Mode, select one of the following process modes:



    Process Default

    Detects the process state of a partition object, and performs processing necessary to deliver unprocessed or partially processed partition objects to a fully processed state. Data for empty tables and partitions is loaded; hierarchies, calculated columns, and relationships are built or rebuilt.

    Process Full

    Processes a partition object and all the objects that it contains. When Process Full is run for an object that has already been processed, Analysis Services drops all data in the object, and then processes the object. This kind of processing is required when a structural change has been made to an object.

    Process Data

    Load data into a partition or a table without rebuilding hierarchies or relationships or recalculating calculated columns and measures.

    Process Clear

    Removes all data from a partition.

    Process Add

    Incrementally update partition with new data.

  3. In the partitions list, select the partitions you want to process, and then click OK.

The Data Process Progress dialog box enables you to monitor the processing of data that you have imported into the model from an external source. To access this dialog box, click on the Model menu, and then click Process Partitions, Process Table or Process All.


Indicates whether the process operation was successful or not.


Lists the tables and views that were imported, the number of rows that were imported, and provides a link to a report of any issues.

Stop Refresh

Click to halt the process operation. This option is useful if the operation is taking too long, or if there are too many errors.
