Path for Hierarchy showing in wrong direction

Hi RAdams ,

I think your guess is right.

Some interesting facts about PATH function are below:

• • The path is not tied to a single level of parent-child relationships. It can return related rows that are several levels up from the specified starting row.
  • The values in Child_columnName and Parent_columnName must have the same data type, text or integer.
  • Values in Parent_columnName must be present in Child_columnName. That means you cannot look up a parent if there is no value at the child level.
  • If Parent_columnName is BLANK then PATH() returns Child_columnName value. 
  • If Child_columnName has duplicates and Parent_columnName is the same for those duplicates then PATH() returns the common Parent_columnName value; however, if Parent_columnName value is different for those duplicates then PATH() returns an error. 
  • If Child_columnName is BLANK then PATH() returns BLANK.
  • If Child_columnName contains a vertical bar ‘|’ then PATH() returns an error.
  •  The delimiter used to separate the ascendants is the vertical bar, ‘|’.
