Object Services attachement list

From FB03, I am able to view archived images from Environment==>additional assignments==>object links==>attachment list.

However, when I am using the Object Services==>attachment list the images does not display. Any ideas why?

I have the following authorization objects.

C_DRAD_OBJ activity 03, document type *, Linked SAP Object *, Status *.

S_WFAR_OBJ activity (01,02,03), Document type *, Object Type *.

Any ideas why from one path it works but not the other?

Thanks,

Christina
