Specification Load using CG33

Using CG33 to load the specification charecteristics in EHS. First the spec header & identifier are created sucessfully with change number. During additive loading of the characteristics with the same change # CG33 treats this as a new spec and error out that spec already exists.

However, the spec was loaded without a change # the subsequent additive load of charecteristics is treated correctly.

How can CG33 be able to do additive load of charecteristic with the change # already assigned to spec?
