So, office members will be able to see records about their clients only, office directors - will be able to look through its office information only (this can be implemented after user segmentation adjustment). And company heads can have access to all the entries, for example.
By the way, in retailCRM it is possible to limit not only call hearing, but also client or order card alteration or wrong delivery date setting. All this can be fulfilled with the help of order management system integrated validation module.
And finally, a small piece of advice from our side to you: start using the new functions in your work right now :)
