How to automatically change the status of a Deal when the task is completed?

Question

Bitrix24

The essence of the task:
When the activity in Bitrix is ​​completed (the Deal or Lead card, not the essence), you need to automatically change the status of this Deal.
For some reason, there is still no processing of tasks at this level in Bitrix. Has anyone faced such a task? What are the solutions?
Perhaps php in the process itself somehow, if you did - please tell me how much it will cost?

Answer 1

At the end of the activity in Bitrix (a Deal card or a Lead, not the essence) - you need to automatically change the status of this Deal.

You can do the following: create a Business process that will create a task and, after completion, check in the business process itself - if it is completed, change the status of the transaction.
The only thing is that tasks will have to be set from a business process, but on the other hand, this will give you standardized processes.
