IBP : Production Source Resource

Dear IBP experts,

I am trying to understand the attribute Capacity Consumption Rate on Production Source Resource. We have the extractor

/IBP/PRODUCTIONRESOURCE_ATTR to extract the data from S/4 HANA.

The details of the extractors are as follows:

As per the blogs, the data will be taken from the extension table /IBP/SOSRES_EXT(not 100% sure).

Can you please explain the logic behind how the capacity consumption rate is calculated when the data is loaded to IBP?

Thanks a lot!!!
