Generation Variant Selection: Fallback Generation Variant when default one not available

Dear expects,

I have a scenario where I need to send a generic SDS , says SDS UN when the SDS of the country version is not available.

Currently, all the country specific conditions are configured in Table 4 condition schema. The last table (Table 5) is not suitable, as it is determined based on regulation type, in my case, it is by country.

Thanks for all valuable input,

KC
