When you share or copy the report, other report editors can also edit the data source. You can still create separate, reusable data sources.\n\nEmbedded versus reusable data sources\n-------------------------------------\n\nData sources can be either *embedded* or *reusable.* Reports can include both embedded and reusable data sources.\n\n**Data sources that you create while editing a report are embedded** in the report. To edit an embedded data source, you do so within that report. Embedded data sources make collaborating on reports and data sources easier. Anyone who can edit the report can also edit the data source as well as modify its connection. When you share or copy the report, any embedded data sources are shared or copied as well.\n\n**Data sources that you create from the home page are reusable**. You can reuse these data sources in different reports. Reusable data sources let you create and share a consistent data model across your organization. Only people with whom you share the reusable data source can edit it. Only the owner of the data source's credentials can modify the connection.\n\n### Benefits of embedded data sources\n\nWhen you share or copy a report, all its embedded data sources are shared or copied along with it. You don't need to share the data sources separately. Having your data sources embedded in the report reduces the number of assets you need to manage, since all your data sources can be contained by a single report.\n\u003e\n\u003e #### Data governance and embedded data sources\n\u003e\n\u003e While embedded data sources simplify collaboration, they can also let viewers access potentially sensitive data and metadata. If you are concerned about strictly controlling access to data and metadata, consider either hiding or removing unused fields from the embedded data source or using reusable data sources in your reports.\n\u003e\n\u003e [Learn more about data governance in Looker Studio](/looker/docs/studio/data-governance-in-looker-studio-an-overview).\n\nHow to tell if a data source is embedded or reusable\n----------------------------------------------------\n\nIf you can see the data source in the Data Sources list on the home page, then it's reusable.\n\nWhile editing a report, in the menu, click **Resources \\\u003e Manage added data sources**. You'll see the type displayed in the first column.\n\nEdit an embedded data source\n----------------------------\n\nAnyone who can edit a report can [edit its embedded data sources](/looker/docs/studio/edit-a-data-source).\n\nShare reports that contain embedded data sources\n------------------------------------------------\n\nThe type of data source makes no difference when you share a report with view access. Whether they are embedded or reusable, [data credentials](/looker/docs/studio/data-credentials) control who can view the data in the report.\n\nWhen you share a report with edit access, those people with whom you share can use any embedded data source you've added to modify the report. Report editors can also [modify the embedded data source](/looker/docs/studio/edit-a-data-source).\n\nConvert an embedded data source to a reusable data source\n---------------------------------------------------------\n\n| **Important:** You must own the data credentials for an embedded data source in order to make it reusable.\n\nMaking an embedded data source reusable lets you manage the data source as a separate asset. By default, editors of the current report will be able to edit the new reusable data source, but you can turn off that option during the copy process.\n\n1. [Edit your report](/looker/docs/studio/edit-a-report).\n2. In the menu, click **Resources \\\u003e Manage added data sources**.\n3. Locate the embedded data source, and then, on the right, click **Make reusable**.\n\n| **Note:** It's not possible to convert an existing reusable data source into an embedded data source.\n\nCopy a report with an embedded data source\n------------------------------------------\n\nWhen you copy a report with embedded data sources, the copy includes those data sources. Copying a report doesn't copy reusable data sources that were added to the report.\n\nIf an embedded data source uses Owner's credentials but the person who copies the report is not the owner of those credentials, that data source isn't copied. Charts in the copy that are based on that data source will show an error asking you to fix the missing data source.\n\u003e You can copy an embedded data source within a report:\n\u003e\n\u003e 1. [Edit your report](/looker/docs/studio/edit-a-report).\n\u003e 2. In the menu, select **Resources \\\u003e Manage added data sources.**\n\u003e 3. Locate the data source, then click **Copy.**\n\nVersion history and embedded data sources\n-----------------------------------------\n\nVersion history for embedded data source is included in the report's version history. To restore a previous version of your embedded data source:\n\n1. [Edit your report](/looker/docs/studio/edit-a-report).\n2. Select **File \\\u003e See version history**.\n3. Select an earlier version of the report, and then click **Restore this version**."]]
