The MapListName and MapName must be specified.

Defined map lists are stored in TDMaps tables MapListTbl and MapListEntry. If AddMapListEntrySPX is called, then defined maps you can access are stored in TDMaps tables MapListTbl and MapListEntry.

No automatic updates are made to existing map lists stored in TDMaps as the result of subsequent DDL statements that drop maps.

A list of maps can only have one contiguous map.

All of the sparse maps in the list must have a different number of AMPs.
