A layer in your map has a broken data link, meaning the layer's data cannot be displayed.
- You can repair broken data links by setting the data source of each layer to the proper location.
- Alternatively, if you do not need the layer, remove it from your map.
A data link is the path that identifies the dataset for each layer in a map. It is specified as part of each layer's properties.
A broken data link means that the layer's data is inaccessible. As maps are moved, copied, and renamed, data links are frequently broken, but can be easily repaired.
