Some layer and data sources are not supported for schema only layer packages. Generally, all standard feature layers are supported in the geodatabase; however, more advanced types and rasters are not supported.
- Replace the layer with one that is supported for the schema only option.
- Remove the layer from your package.
The following layers and datasets do not support the schema only option for layer packages:
- Network datasets
- Tool layers
- Raster catalogs
- Raster mosaics
- Basemap layers
- Nongeodatabase feature classes
- Parcel Fabric datasets
