If grouping is used for balancing, the data must include the corresponding grouping attribute.

Make sure that:

• the grouping attribute is specified for all required objects;
• objects in the same group use the same group identifier;
• there are no duplicate or conflicting values.

If a territory consists of multiple separate parts, the system can process these parts together when grouping is applied.

After grouping is complete, check the result on the map. Parts of the same group may be located in different areas, so the distance between them does not necessarily indicate an error.
