Create privilege to allow user group can search ECO & BOM and do anything else in user group only.

Hi ,

I don't know  create a role and privilege where the user can only see  their own user group.
 
Example :
USER GROUP CUST1
user A;
user B;
user C:

USER GROUP CUST2
user X;
user Y;
user Z:

I need :
1. user A import Bom & create ECO load to agile system. we need user B,C can search and do anything else.
2. And USER GROUP CUST2 do not search and do anything else in USER GROUP CUST1.

My server = Oracle sun solaris

My Db = Oracle enterprise edition 12.1.0.2

My Agile version = 9.3.5 Oracle Agile Product Collaboration
