Data view troubleshooting

While working with data views, you may encounter warnings about your data view configuration settings. This topics details possible warnings and how to address them.

Data Views page

While browsing the list of data views, you may encounter the following warnings.

Alert tag

Query sources that include a yellow or red alert tag indicate that you have an issue affecting your view of the data view. There are several contexts for when an alert tag displays:

• Unknown community tag

  

  Yellow alert tags that read Unknown Community indicate that you have insufficient permissions to access the community or that has been deleted. You must be a member of the community to access its data. Additionally, you cannot edit the query for the community until you are member of the community. Request that a community administrator add you to the community.

• Read access tag with community name

  

  Yellow alert tags that display the community name indicate that you are a Community Administrator or Community Member with read access, but not a member of the community itself. Community Administrators can use the visible community name to add users to the community. For more information on adding a user to the community, see Manage users in a community.

• Cross region opt out tag

  

  Red alert tags indicate that the data view queries a namespace that has opted out of Cross-region data sharing, but the data view resides in a different region. For more information, see below.

Data View page

You may encounter the following warnings while editing a data view.

No included fields

If the field set for a query includes no fields, an alert of No Included Fields displays. You can correct this error by adding one or more fields to the query. For more information, see Manage data fields.

No Included Fields

There are included fields that don't map to anything

If one of your queries includes fields that do not map to anything, an error of There are included fields that don't map to anything displays at the bottom of the field sets.

Field set error

You can correct this error by finding the individual fields that do not map to anything and removing them. Fields that do not map to anything are denoted by the alert icon. For more information on removing a field from a field set, see Manage data fields.

Manage Queries

While managing data view queries, you may encounter the following warning.

Cross region processing opt out

If you encounter a warning of This namespace does not allow data to be processed outside of the region where it resides, this message indicates that the namespace has opted out of sharing its data across regions, and the currently selected namespace has a different primary geographical region. Therefore, the data view cannot be processed in the currently selected namespace. For additional information, see Cross-region data sharing.

You can encounter the message above in different contexts:

• While adding a query

  While you are adding a query, CONNECT data services compares the region of the current namespace against the region of the namespace you are adding to the data view. If you attempt to add a namespace that has opted out of cross region data sharing, and the currently selected namespace has a different geographical region than that namespace, the source is unavailable and therefore cannot be added. A tooltip displays if you mouse over the source:

  

• While managing an existing query

  If a data view is created that includes a namespace that later opts out of cross region data sharing, an alert displays in the Query panel that the data view includes a source that cannot be shared across region:

  

  When the query that includes a disabled source is selected, the following message displays:

  Cross Region Data Sharing Disabled: This namespace does not allow data to be processed outside of the region where it resides.

Data view invalidation

If the data view is modified, any cached information is reset. The data view re-resolves the next time that information is requested.

No guarantee is made of the durability or lifespan of cached information. If cached information is invalidated, the data view is re-resolved the next time that information is requested.

Cached information may be reset under any of the following circumstances:

• The data view is modified

• A community referenced by the data view is modified (for example, sharing is paused)

• The cached information expiration time elapses

• System maintenance
