In the above embodiment, when the transaction data acquired from the transaction system is configured according to the virtual table and the field in the logical basis model, data extraction is required to be performed once according to the configured rule of the data to form the logical data, and the extracted logical basis data is displayed in the logical basis card. The logical basis is similar to a custom table, a physical table can be selected for corresponding, and conditions are set to correlate and filter the physical table to obtain data needed by calculation. The logical basis is synchronized into the data set in the settlement model for use in subsequent calculations. The logical data is a field in a custom logical basis, which can select a physical field in a physical table to correspond to, and set a condition to screen out required data. The logical data is synchronized into data items in the settlement model for use in subsequent calculations. The function of the logic basis card is to summarize and display the configured logic basis on the logic basis model query interface, all the configured logic basis can be queried only by setting the logic basis display, and the card can be displayed under the corresponding settlement main body and logic container.

In order to compensate for the settlement error, in an alternative embodiment, after performing clear calculation on the electric charge in the new settlement scene by using the settlement rule expression of the new settlement scene, the method further includes:

step S301, generating a bill of the new settlement scene according to the settlement expense, and sending the bill to the settlement subject of the new settlement scene;

step S302, under the condition that the bill is in dispute, the electric charge in the new settlement scene is subjected to clearing calculation again to obtain updated settlement charge;

step S303, when the updated settlement expense is different from the settlement expense, calculating the difference between the updated settlement expense and the settlement expense to carry out compensation settlement.

In the above embodiment, after the dispute is processed and the bill for settling the electric charge is issued, the market member receives the check bill, and can submit the objection to the objection part, and support the function of adding the accessory such as the related certificate. For settlement with disputes, the transaction company will conduct dispute handling and replying. The member's disputed amount is added in the refund clearing to the next settlement period. The compensation settlement module is used for re-settling the historical month after settlement. In general, when the historical month electric quantity adjustment and the internet surfing electric quantity adjustment occur, the historical month needs to be re-settled, the settlement rules still adopt the historical month rules, the result generated during re-settlement does not influence the completed result of the historical month, the re-settled result is compared with the settled result of the historical month, and the deviation is used for carrying out independent settlement payment. And for the settlement bill without disputes, issuing the settlement bill to a financial management and control fund settlement system to form an electricity purchase fee settlement notice through bill issuing, and completing subsequent fund payment processing.
