+-- Function: runs.update_partitioning_parent(5)
+--      Update the Parent Partitioning for a given partitioning ID and copies measurements and additional data from parent.
+--
+-- Parameters:
+--      i_id_partitioning                - id of the partitioning to be changed
+--      i_id_parent_partitioning         - id of the new parent of the partitioning,
+--      i_copy_measurements              - copies measurements from parent partitioning to child
+--      i_copy_additional_data           - copies additional data from parent partitioning to child
+--      i_by_user                        - user behind the change
+--
+-- Returns:
+--      status              - Status code
+--      status_text         - Status message
+--
+-- Status codes:
+--      11 - OK
+--      41 - Child Partitioning not found
+--      42 - Parent Partitioning not found
