Last

The Last() function returns the last item in a list or concept set.

For (persistent) lists it must indicate a field of that list.

This function is NOT SQL compatible. For more information about SQL compatibility, see our documentation.

Returns the last item in the given list or concept_set.

Returns Unknown if one of the parameter values is unknown or outside the common valid date boundaries.

Possible fault message in expression editor: Invalid call to a function: parameter mismatch at position(x,y): Last

This could mean that there is no field of list used, but only the (reference to a) list.

The Last function needs a field from list where filter construction, or if you only want to get the last row of a list, use RowId([list]) of [list] where [filter].
