Hello Chuin,

We haven't come upon such an issue before and we are not sure what could be causing it. Could you please isolate the problem in a simple working demo and send it to us via a support ticket?

Hi,
I managed to understand why, my ReoccuranceParentID is empty. After putting that in it works.
Thanks for your help.
