Tableau Connector Pro for Jira enables you to aggregate selected fields and import them into Tableau Desktop using Tableau’s **OData** protocol and **Web Data Connector **API.

## OData Connector

### Import aggregated fields into the Issues table

- The Tableau Connector Pro for Jira app supports aggregating selected fields into an **Issues** table.
- However, in scenarios involving a large number of one-to-many relationships, the OData will still generate multiple tables. For example, for the fields Comments, History, and all integration fields such as Tempo, Projectrak, and Assets.
- To aggregate fields into the **Issues** table when creating a new OData connector, select the field **Aggregate fields into the Issues table**.

- Once the data is imported into Tableau Desktop and the configuration for aggregated fields is changed on the OData configuration screen, existing reports can break or behave inconsistently.

## OData report portability between aggregated and non-aggregated fields

- If you want to fetch reports with both aggregated and non-aggregated fields, then you need to maintain two sets of reports for each configuration: one for aggregated mode and another for non-aggregated mode.
- Tableau reports created using the WDC connector are not compatible with the OData Connector, even when the option **Aggregate fields into the Issues table** is enabled.
- Additionally, existing WDC reports are not compatible with the aggregated OData model, even though their fields are the same.
