We need to create a process. Let's say that we have project "My project" with document reserach type "Doc". We will assign to "Doc" a process what will register this document, fill attributes of this document and assign macro containers to it.
Because we will assign macro containers to this document, we need to create new research type of macro container, for instance "Macro". Add Research Relation between document and macro container (see paragraph How can I add new research relation). Save changes.
Select "Doc" then click on command "Assign Processes", Assign Process screen will be opened. Select process "Register doc" and click . Save changes.
