And S703, tax number changing processing.
When the enterprise tax number is changed in the business, the enterprise tax number hierarchical relationship tree and the enterprise tax number in invokable transaction of each business system need to be synchronously changed according to the enterprise tax number relationship rule, otherwise, the business can not perform transaction inquiry and subsequent invoicing operation according to the enterprise tax number.
And S704, updating the organization tax relationship tree.
And updating the organization tax relationship tree according to the changed tax.
S705, the new tax number and the old tax number of the invokable organization are mapped and changed.
And for the invoicing institution, if the invoicing transaction processing is initiated, the updated institution tax number relationship is used for inquiring new tax numbers.
And S706, historical invoiced transaction processing.
The tax numbers in the historical invoiced transactions are old tax numbers, and after the tax numbers are changed, the change relationship of the tax numbers needs to be recorded, namely the new and old tax numbers change the relationship, so that business personnel can inquire historical data and summarize the data conveniently.
And S707, data uplink.
And recording an organization tax number relation tree, a tax number change relation, an invoicing transaction result, change data and the like on a chain.
And S708, inquiring and maintaining the organization tax number.
And providing a visual page, carrying out operations such as changing and inquiring of business data, and checking and tracking in real time after changing.
