We want to be possible to :

restrict the access of some users to already uploaded documents in Share Point based on security roles.

What we mean by this is –

a. User A with lower security role (like Sales user) should be able to see only documents uploaded by him

b. User B with higher security role (like Sales manager) should be able to see his own as well as User A’s documents.

At the moment this is not possible in Dynamics and Share Point
