Dear Antti,

Thanks a lot for your help.

When assigning this interpolation rule I forgot about this point about default value. That's why there was interpolation rule "5" with start in 2020. I will remove this interpolation rules "5", this will resolve my problem.

So if I understand correctly it was the problem of not being interpolated to 2016 in combination with "ILED", it was cost free to invest in it earlier than 2020, despite starting point "2020"?

Thank you very much for your help,

Bakytzhan
