By default, the editor recognises the client address in documents, which is stored in Abacus in the program 6311 "Client information".
The client address is required so that the editor can recognise whether it is an incoming or outgoing invoice.
As soon as the address on an invoice is not analogous to the client address, this cannot be recognised by the editor.

In this case, it is possible to store addresses in the DeepBox. There you can store several addresses or add similar spellings to the client address.
The behaviour of the editor is as follows: As soon as a document with one of the addresses is analysed, the editor recognises it and can assign whether it is an incoming or outgoing invoice.
The addresses are only there so that deviating addresses are also recognised.
