Restrict the user access based on sub-inventory wise

Hi,

We have the trading organizations in statewise like Tamilnadu, Karnataka, etc..

These trading organizations have different depots in various towns like chennai, madurai, coimbatore, etc..

Each depot is created as separate sub inventory under state organizations.

For each trading organization we have created one user id for access and depots are in different locations and

also handled by different persons.

Example - If a Tamilnadu trading organization user login, he can access all the sub-inventories(depots) associated with this

                organization like chennai, madurai, coimbatore, etc..

      

                We want to restrict the users based on depot, so chennai depot user is not allowed to make transactions for madurai depot.
