You can set moderation levels for a certain number of actions. This allows a user to moderate a proforma, sales order, or financing plan. You can also set levels (IE how many moderation levels are needed for each action) and set the level of each user.

To do this, in Moderation settings, set the level of moderation required by type (In the Max level of moderation column) and enter which level corresponds to each user by clicking on the pencil and searching by the username.
