OM - Moving Org Unit don't change relat 002 between my Position

Hi,

I have a problem with my OM system,

I have five org unit (A B C D E) everyone with one position head of own organizational unit, a b c d e.

this is my hierarchy

A

(a)

     B

      (b)

          C

           (c)  

     D

      (d)

          E

           (e)

I have this relat in HRP1001

Org Unit     Positions

A 002 B     a 002 b

A 002 D     a 002 d

B 002 C     b 002 c

D 002 E     d 002 e

I'm moving (with ppome transaction) org unit C with its position c, under org unit D.

A

(a)

     B

      (b)             

     D

      (d)

          E

           (e)

          C

           (c)

After the moving in HRP1001, relationship between org unit has changed B 002 C (is delimited) D 002 C (is new).

But, I don't have relationship between Position d and c (d 002 c), and relationship between position b and c (b 002 c ) is still valid!!!

Org Unit     Positions

A 002 B     a 002 b

A 002 D     a 002 d

D 002 C     b 002 cd 002 c

D 002 E     d 002 e
