I am using sharepoint nintex 2013. I would like to check the possibility of my planned ideas. I have a customer list, company list and sales list. I want to grant smart access rights sales list. For example, if I have 2 Sales guys (A, B), working for 2 different locations (C, D) and have 2 different expertise (E, F) respectively, the Sales A is only able to see/ access the information of his customer information: his customer working for location C, with expertise is E. Sales A is not allowed to see/access Sales B's information. Please refer to attached screenshot. Red lines are to show the relationships between lists. Is it possible to do that in SharePoint? Thanks for any comment.
