-When you select an [elastic tables](/power-apps/developer/data-platform/elastic-tables#partitioning-and-horizontal-scaling) in the copy activity sink, the connector mapping supports the `partitionid` column, as the elastic table contains a system-defined `partitionid` column. You can map your source data column to the sink's `partitionid` column. If not mapped, the primary key value is used as the default value for the `partitionid` column. For more information about the `partitionid` column in Dataverse elastic tables, see this [article](/power-apps/developer/data-platform/use-elastic-tables?tabs=sdk#specify-partitionid).
+When you select an [elastic tables](/power-apps/developer/data-platform/elastic-tables#partitioning-and-horizontal-scaling) in the copy activity sink, the connector mapping supports the `partitionid` column. You can map your source data column to the sink's `partitionid` column. If not mapped, the primary key value is used as the default value for the `partitionid` column. `partitionid` can be used in Dataverse alternate keys or primary key scenarios on the write path. Each elastic table contains a system-defined `partitionid` column and has an alternate key named `KeyForNoSqlEntityWithPKPartitionId`, which combines the primary key of the table with the `partitionid` column. For more information, see this [article](/power-apps/developer/data-platform/elastic-tables).
