cj20n milestone attachment file does not work

Hello,

When we create attachment files for Milestone, they are linked to network (BUS2002) and not to milestone (MLST_NETW), as expected.

Example :

       Network - 1000

                  Activity 01

                        Milestone A

                               Attachment file X

                        Milestone B         

                               Attachment file Y.

Actually, in the Network, Activity and Milestones all files created under the Network 1000 are displayed.

Our customer would like to see attachment file X and Y only into there respective Milestone.

In OAC3 , we added object type MLST_NETW with doc type BDS_ATTACH, but unfortunately, this entry has no effect.

Do you see any solution to resolve this problem ?

Thanks for your help,
