Archivelink Documents: Access to link

Hi,

We have created a link to object type BUS2000111 (Opportunity), and a content repository, and a link table. But our problem is that the link appears in all Transaction Type "Opportunities". We have different users of SAP CRM, and both use, the object type BUS2000111 but diferente transaction types. And we want not that one of them can see the link in his opportunity type.

Can I restrict the access to link by authorization object?.

I did a trace but I didn't check any object authorization related archivelink. I have found object S_WFAR_OBJ, but don't work for my request.

Our objective is the folder with link doesn't appear for one user type determinated.

Best Regard,

Mario.
