Return value
String. Returns the display value when it succeeds and the empty string (“”) if
an error occurs.

the code table, but the user sees a value from the display column. Use
LookUpDisplay to get the value the user sees.

Examples This expression returns the display value for the column unit_measure:
LookUpDisplay(unit_measure)
