You can find a list of all processes on this page. Here you can search all processes and open the linked documents.

The search term "ECM process overview" not only lets you search/retrieve processes, it also lets you create them manually. As a rule, this is not required, since all processes are generated automatically via the process numbers by Microsoft Dynamics 365 Business Central. External documents, such as purchase invoices, are, by default, also assigned to an internal process.

Processes can be created when documents were generated entirely outside of the Microsoft Dynamics 365 Business Central document flow, such as important correspondence letters. For each document with the relevant origin, for each document type, or for a group of documents related by content, a process can be manually generated to which the individual documents can be assigned. The organization of such processes is up to the user and should therefore be fine-tuned within the company.
