When you open a map or scene in a project, ArcGIS Pro looks for the data referenced by each of the layers in the map. When a data source cannot be found for a particular layer, that layer doesn't draw, and its broken status is indicated in the Contents pane with a red exclamation point .
A layer needs repairing if the data source it references has been moved, renamed, or deleted or is inaccessible for some other reason. If you don't know the new location of the data source used by a layer that needs to be repaired, or if that data source is no longer available, you can leave the broken layer as is and continue to work with the map. The broken layer will continue to be shown in the Contents pane with a red exclamation point. If you no longer need the layer, you can remove it. If the connection to a web layer is broken, you will not be able to repair the data source; instead, remove the broken web layer and add the new web layer to your map or scene.
View all layers with broken links
You can filter the view of the Contents pane to show only those layers with broken data source links.
- In the Contents pane, click and click Broken data link.
Repair a broken link for one layer
If you only want to repair a broken link for a specific layer, you can change the data source property.
- In the Contents pane, right-click a layer, and click Properties to open the Layer Properties dialog box.
- Click the Source tab.
- Click Change data source and browse to the source.
- Click OK.
Repair broken links for multiple layers
You may find that several layers in your map need repairing. For example, if a geodatabase containing data sources that are used for multiple layers in your map has been moved or renamed, all these layers will need to be repaired. When the repair to the data link is made from the Contents pane, ArcGIS Pro repairs the selected layer using the data source you browse to and automatically repairs other broken layers if it can find their data sources in the same location of the data source you specified.
- In the Contents pane, click the red exclamation point next to a layer to open the Change Data Source dialog box.
- Browse to the source.
