The tax invoice ((invoice type code (BT-30) = 388) and (invoice transaction code (KSA-2) has "01" as first 2 digits)) must contain the supply date (KSA-5).
What the rule checks
As the rule set's publisher wrote it. The rule runs on every element the context matches, and fails where the test is false; the validator reports the line of that element.
cbc:InvoiceTypeCode[substring(@name, 1, 2) = '01'][/ubl:Invoice[cbc:InvoiceTypeCode ='388']]
exists(//cac:Delivery/cbc:ActualDeliveryDate) and normalize-space(//cac:Delivery/cbc:ActualDeliveryDate) != ''
