How long will it take to learn how to build business processes in cloud Bitrix24?

Question

Bitrix24

We bought Bitrix24 at work, now we want to manage business processes ourselves, create logic, etc.
For example, now there is a task of generating a mailing list based on the available data in the Company section. For example, a company has a custom field "Company type". If you filter in CRM by company type, then the filter will not work and you need to create a similar field at the level of the "Contacts" section. And for automation, so that by selecting a field at the company level, and it is automatically selected for contact, a business process is already needed.
To solve a similar problem, how much time do you have to spend on training? Subject to knowledge: theory and some practice php, js

Answer 2

Your wording is not very clear: you want to know how long it takes to "do this" or "solve almost any problem"?
Your question doesn't make sense.
Do you want to understand what? How long will it take to study the whole system with all its subtleties and nuances? How long does it take to learn business processes? How long will it take to learn the rest? How long will it take to complete this particular task?
Your task can be solved on the rest in about 3-4 hours if you know what to do and how it works inside. You can figure out and understand how it works inside from 2 hours. Thus, for a specialist with experience without experience in Bitrix24, it will take at least 5 hours to solve this situation, and for a person who does not understand the topic, it may take several months.
Please, specify your question.
