[Jingbo Ye]

Hi, everyone. I am a QuantlibXL user. I've been confused by this question for a long time and can't find an answer anywhere. If anyone has any lead please let me know and I really appreciate that! Thanks.

Hi, the links make clear the usage of trigger and permanent, however, the functionality of the overwrite flag remains a mystery to me. Any further explanation would be appreciated.

Thanks,
Brian

Hi Brian,

if true you will overwrite an object with the same id if already
existing in another cell. If false (default value) and an object with
the same id already exists in another cell, you will get an exception.
This is only relevant if you specify the id, otherwise every cell gets
its own unique autogenerated id.

You can try by creating an object in a1 and another one in a2 with the
same id, first with overwrite = false and then with overwrite = true.
