Functional Details #!N #!N In a Composite Field, positions (and any 
position-dependent component entries) along a common boundary are shared between partitions. 
Unless this duplication is taken into account, certain operations (e.g., calculations 
of statistics or the number of points in a Field) may 
produce incorrect results. This routine invalidates all but one of the 
duplicated positions. #!N #!N Return Value Returns the input Object with 
the duplicate positions invalidated or returns NULL and sets an error 
code. #!N #!N See Also #!N #!N  #!F-adobe-times-bold-r-normal--18*    #!Ldxcul,dxall1193 h DXCull  #!EL  #!EF #!N
