Item name change in one item master org is reflecting another item master org

Hi,

For example we are having three operating unit with three different item master organization in one instance.

OU 1=Item master org A

OU2 =Item master org B

OU3=Item master org C

Each OU is having 3 organizations

OU1=A1,A2,A3
OU2=B1,B2,B3

OU3-C1,C2,C3

Item xyz has been defined all the three item master organizations and respective child organizations. When we change item name from xyz to xyz_1 in item master org A by using profile option INV:Updatable item ,what will happen.

It will reflect the same changes in other item master organizations B,C and organization B1,B2,B3 and C1,C2,C3 will have item name xyz_1
