Reason and Prerequisites

This problem is caused by a program error.
In the class cl_salv_bs_result_data_table in the method merge_aggregation, the node in the KeyfigureTree is set as the parent for all corresponding items for each aggregation result. You insert the aggregation node in the result table before setting the parent information on the data items. The system cannot determine the child nodes as a result.
