Scenario:
The .csv file is imported through the .csv import option present within the integration tab of Web TimeSheet. Once imported,it is noticed that the Tax code does not get automatically updated whenever the Net Amount is entered through the .csv file. However, whenever we manually enter a Net Amount, the Tax code gets updated.

Resolution:
Importing expenses is a basic import. It's capable of inserting a value into one of the supported fields but does not perform any calculations on any of this data, and likewise, it cannot infer the tax code and calculate the tax amount.
