If in MetaKocka multiple different backgrounds are added, it is possible to set the rules on how to automatically set them up based on the printed documents. The following rules are available:
- list of ID report labels,
- the receiver's country or the customer's country, if the receiver is not set
- the original online store of the invoice or associated sales order, if the invoice was generated based on the sales order.
Multiple rules can be set simultaneously (for example Foreign invoice + receiver's country Croatia + Shopify store 1). If the printout matches several definitions, the one that meets the most criteria can be selected.
