Partial implementation decision tree diagrams

In the central master data application and in the incoming document system, market messages are processed, which must be checked according to the specifications of the BDEW (Federal Association for Energy and Water Management). The systems are programmed with .NET code and have SQL databases as a basis. Decision trees are specified for the different application areas (for example GPKE, WiM Strom, GeLi Gas, excess and shortfall billing). Based on the paths traversed in the decision trees, the possible response codes used in the EDIfact response message are determined. Based on the response codes, the sender of the original message can determine which check steps of the decision tree have been traversed. The structure of the decision trees and the response codes are kept in master data tables of the two systems.
