Repairing broken links for multiple layers When you use this button to repair a layer, the application will only repair the current layer, even if the data sources of other layers that need repairing can be found in the location of the data source you specify. Select the desired data source on the Data Source dialog box, and click Add to repair the layer. This lets you specify the layer's data source by browsing to it. If you only want to repair a broken link for a specific layer, click the Set Data Source button on the Source tab of the Layer Properties dialog box. There are a number of ways to repair broken data links, which are described in the following sections: Repairing a broken link for one layer You can immediately tell whether a layer on your map has a broken data link because it will have a red exclamation point next to its name in the table of contents, and the check box next to the layer will be unavailable.Ī layer needs repairing if the data source it references has been moved, renamed, or deleted or is inaccessible for some other reason. If ArcMap can't find the data source for a particular layer, that layer won't be drawn. When you open a map, ArcMap looks for the data referenced by each of the layers in the map.
