go to post Mark Franssen · Nov 1, 2021 It works now, thanx everyone: I now have "HL7.{PID:4.1} Contains "Relatie"" filled in the rule. When testing i used the wrong Doctype apparantly, i should use: 2.4:ADT_A01 Probably the condition i posted in the beginning should have worked to, but this one is more simple to read and use.
