Question

1C-Bitrix

Tell me, how can I find a business process in the boxed version of Bitrix24 using php using the fields of this document?
Let's say there is a business process "Invoice for payment", it has fields such as: Date, Amount, Counterparty (link to CRM). How can using this data, using the php code, find out the id of the process to which this data refers?

Answer 1

Business processes are ordinary lists. Lists are ordinary infoblocks. Those. if you need the document itself, then look for the elements of infoblocks. If the process itself (business process tasks), then look in the b_bp_* tables, specifically in b_bp_task
