SPP : Demand category not found Error

Hello Experts,

I want to load SPP demand history data using CSV file.But while loading the CSV file I am getting an error message stating " Demand Category not found".

I have already transferred and activated the InfoSources 9ADEM_CAT successfully.Demand category "None" is also correctly maintained under RSDMD.

Can you please guide what other settings I can check to resolve the error message?

Appreciate your help.
