Hi,
The values in DWH_INV_SUMMARY_FACTS, and in your example, DWH_INV_SUMMARY_FACTS.BASE_TOTAL_HOURS are getting summed up from the values in DWH_INV_ASSIGN_PERIOD_FACTS table.
And before the data gets to DWH with Load Data Warehouse job, in PPM, the data is taken from view DWH_INV_ASSIGN_PER_FACTS_V. There is no way for you to actually see this from the Domain properties, I think the only thing you will see is the table/fields, but it won't show where the actual data is coming from.
Please let me know for any questions.
Kind Regards
