In order to change the order of an eBiss node in the hierarchy, the specific entry in the table Edit dbo.Node. Relevant is the key in the field [ParentNode_oid]. If the [Oid] of any other existing node (which is not child of the node to edit) is entered into the field [ParentNode_oid], then the hierarchy changes accordingly.
Note: These changes are made at your own risk. Therefore, before starting work, stop the eBiss Service and all eBiss Clients and create a backup of the database! Please also note that this may also affect existing user rights or make adjustments necessary.
