Itgenemd007 error when logging on to Exact Online UK due to duplicate company information

Across all versions and products of Invantive SQL, it is currently not possible to log on to Exact Online UK environment.

An error similar to the following occurs upon log in:

itgenemd007: An element with the key ‘NUMBER’ already exists in a dictionary of Int32 and String.

Due to an Exact Online upgrade, the API used to retrieve company information now contains duplicate rows. The cause seems to be the introduction of the legislations XI and XU in addition to GB.

A case has been raised at Exact Online requesting a solution.
