How to bulk edit records in Bitrix24 (cloud)?

Question

CRM

There is a cloud, the tariff Company.
It is necessary for a large number of transactions (filtered or all at once) to edit such and such a field.
How can this be done in a standard way?
So far I have settled on the following: you can create a business process that changes the desired field. But BPs can only be started when a record is created or modified.
When editing one deal, the BP works successfully. But how to make this BP work for several thousand transactions?

Answer 1

Good afternoon!
The question was asked a long time ago, but since I periodically receive the same questions from clients, I will explain the logic.
2 business processes are created, let the first start, the second - work.
In start we create a list - a multiple variable. We load the id of the deals that need to be edited into this variable.
Next, add an iterator (iterates over the values ​​of multiple variables) in actions (activities), add the start of the business process, and the id of the entity for which you want to start the business process, set the value of the iterator and select the work process template. Each time in the iterator circle, the value will be the id of the next deal.
Thus, we will launch a business process (work) for all transactions that will make the necessary changes.
By the way, the easiest way to get deal ids (if there are not many of them) is to upload deals to csv, copy and paste them into a business process variable.
