Use the Import Location Mapping window to define the different methods that will translate the linear reference system(s) to the base ("basic") linear reference system used by AgileAssets (which in turn is defined in the Setup Location References window). Multiple records may be inserted into this window, with the Mapping Statement column providing the statement that performs the translation.
The entries here form the drop-down list found in the Import Location Mapping column of the Import window. The label used in the drop-down list is the text entered in the Import Location Mapping column of this window.
