Open Documents & Folders
The documents and folders set up in the Link Setup for the parameter translation between Microsoft Dynamics 365 Business Central and the connected d.velop system define the call parameter with which the document or folder is called.
The call can be made via the respective document.
Sales Invoices (Example)

You can call the document or folder via the ECM button in the menu bar.

Filebox Export Entries and Report Export Entries
A document can also be called via the export entries. In this case, the ECM Response ID is used.
