PROBLEM

Grid EXPAND() function does not expand as expected with zone value of zero

Last Published: April 25, 2020

Description

If there is no value of zero in a grid, and zero is specified as a selected zone along with another valid value, the EXPAND() function output will be identical to the input.

The expand function would be expected to operate on the other listed selected zone(s).

Solution or Workaround
