Implemented logic: 1. If the company was written to the subscriber first, then in the task that the company will be created, we become the author, and the subscriber becomes the client. If the subscriber wrote to the company, then the subscriber becomes the author and the client. 2. If in the process of correspondence with the client we understand that we already have this person in the contact database and combine it with the desired contact. Correspondence will continue in the current task, a new task will not be created. 3. At a certain stage, we change the BP from a task to an order, correspondence with this client can now be continued in the current order. 4. When the order is closed and the client writes a new message in direct, a new task for correspondence will be created and the client from the contact database will be indicated, because previous process closed
