The default value of a field can be filled in on various levels:

• Customization of the form by the user,
• Customization group,
• Custom form,
• Restricted access group,
• Dictionary: applicable to all users. See Dynamic default value

The level depends on the group of users to which this default value applies.
If default values are defined on several levels for the same field, the value applied is that of the level closest to the user. This corresponds to decreasing priorities in the order of the above list.
