Does anyone know if there is a way to prevent internal invoices from updating AR? We tried setting the cash payment parameter on the payment term to '1 - Yes - cash payment without update of AR,' on the internal customer but it doesn't appear to work for MUC invoices. This relates to MUC type 1 orders, where goods are moved from our Polish warehouse to one in another country, both owned by the same legal entity. However, with the Polish KSeF regulations starting February 1, 2026, we must report these transactions using an internal invoice submitted to KSeF.
