I have a business operation in an ensemble production to which I can send a test message which requires a date input. However, I can not seem to find out how I write the date in the test message. 1980-01-01, 01-01-1980, 50000 (cache integer encoding). But I constantly get an error: <ZODAT> zDateOfBirthDisplayToLogical+1^Ckey.Customer.1
Just figured it out myself; 01/01/1980 is accepted.
