Where an invoice includes goods and services falling into more than one category (for example, a hotel bill including accommodation, meals, newspapers etc), you should not 'split' the invoice over more than one line, with the same Purchase reference number on each. The refunding Member State may interpret this as a duplicate entry and may query or reject your claim. Instead, you should use one of the options shown below. The first bullet is the preferred option:
Use 'Code 10 - Other', and itemise all the appropriate codes and amounts in the free-text 'Purchase Description' field.
Show only the code that relates to the highest-value item on the invoice.
