Why ESS reacts different then PA30

[lorenz_knecht2]

We have the issue that INFTY 0009 SUBTY 1 with Time Constraints 2 allows in PA30 altought more than one records at the same timeslot. In ESS it throws an Error PBAS_SERVICE #051. Why is it this way? Why PA30 dosn't check the consistency?

Thanks a lot for any ideas

PA30 is much older. ESS use the decoupled IT framework, which provides more options and flexibility, but relies more on consistency. PA30 is way older then modern programing concepts like MVC.

Portal also uses XSS* classes for ESS so the coding could be slightly different and have more validations.
