After importing a large number of documents, all based on our configured document number syntax, it turned out that the system does not recognize the document number sequence imported. As a result, any new facility document created uses the last previously known sequence number, irrelevant to the import. Hence an imported document number is re-used and it becomes impossible to release the new document to the master environment.
When importing documents, based on the configured document numbering syntax, the import should recongnize the syntax and update its sequence register for the next document created.
