Hello,
As per my understanding, you want the sales team have multiple hierachy and the proper access right such as sales team leader can see only his/her team's document, however odoo standard will have several limtation:
1. As per the access righ you can only have 2 option: see own documents or see all documents, that mean see all document of all sales teams not helping when you want to have access right for one team only.
2. Odoo do not have the sales team hierachy feature and cannot give access right by sales team or parent sales team.
Therefore we develope a module to fix that, you can check out this:
