|Map Uploader (Pre-MapInfo Pro v16) / Appendix A- Supported Layer and Table Types|
MapInfo Professional allows users to open the same table (from the same or different locations) and add it multiple times as layer in a map. The Spectrum™ Technology Platform will not upload the same layer more than once in each map as it will result in creation of duplicate layers which are not supported by Spectrum. In this scenario the Uploader will allow the first occurrence of the layer to be uploaded but will not upload the remaining ones. If you wish to upload the same layer multiple times, for example, with different style override or other settings, you can add it to a new map which can be uploaded.
