Basically WebOffice 10 R3 supports 'WebOffice-Relates' as well as 'ArcMap-Relates'. More details on 'WebOffice-Relates' please find in chapter Relate (1:n) Relation with other Database Table. An 'ArcMap-Relate' uses those relates, that are defined on a layer in ArcMap. WebOffice 10 R3 supports ArcMap-Relates
•between a layer and a table and
•between two layers.
Note: If a relate is defined between two layers, both layers have to be in the same data frame. All other configurations are not supported by WebOffice 10 R3.
'ArcMap-Relates' will automatically be transferred to WebOffice 10 R3. If more than one relates are defined on one layer, only the first one will be transferred to WebOffice 10 R3. The column width of the 'ArcMap-Relate'-result is by default 25 and cannot be extended. It is possible to define the order and the visibility of the fields of a relate result in the table properties or layer properties in the tab 'Fields' (ArcMap).

Table properties in ArcMap - define order and visibility of the 'ArcMap-Relate'
Note: If more than one layers are defined on a layer, WebOffice 10 R3 only supports the first relate.
Relates will also be used for 'Free labeling', more details please find in chapter Free Labeling.
