In reinsurance table the liability amount and premium amount of the data_type_Cd =1 is equal to the sum of the liablity amount and the sum of the premium amount of the data_type_Cd != 1 respectively

In reinsurance tables, the liability and premium amounts for data_type_cd = 1 (summary/aggregate data) do NOT necessarily equal the sum of amounts for data_type_cd != 1 (detail records). While this might seem intuitive, reinsurance systems often have complex data relationships where summary amounts are calculated differently than simple summation, or may include adjustments, fees, or aggregation rules that prevent direct equivalence.
