Original Question: RCM Data loader Consequence categories broken by Indraneel Sengupta
The Economic consequences values using the data loader aren't loaded. Me and Mario Peralta have conducted few tests and the consequence categories which are loading mismatched values are Downtime Cost and Failure Cost in the UI post data loading and these values are mentioned correctly in the template. Find attached our SD analysis type for RCM with the Economic consequences set up.Is this the way the loader should work or something is broken?Copy of AW RCM2 Example from MWSPC_TEST9.xlsx

Question: RE: RCM Data loader Consequence categories broken by Mario Peralta
Indraneel Sengupta and I discussed the data loader columns and economic consequence attributes.
Below you'll see the logic when the data is keyed in using the UI.
We compared this with the logic used when using the data loader.
See the data loaded below. We noticed that only the bold values are considered for the economic consequence evaluation.
There is a problem in the failure tab. The aggregations are showing a different results. As per the UI logic, downtime cost and failure cost shouldn't be data loadable as they are aggregations?
The APM help defines Total cost:
Total costsAPM calculates the total cost by adding the lost production, repairs, labor, secondary damage, and other costs.
Thoughts?

It sounds like the same problem Daniel Hillman and Paul Goodfellow reported for Oman LNG. They reported the problem against the RBI data loader, but the logic is in a base class and applies to RBI, RCM, and MTA.
Enter a separate bug, at the very least it will initiate a test to make sure it works for all analysis types (that support evaluations
For OLNG we didn't fix this part of the loader. It follows the same logic in RBI. What I'd like to understand is what's the correct way to calculate the economic consequence value so that we can explain this to the user and determine if the current calculation is right or wrong?
It's not that black and white. If risk is being evaluated as part of the analysis (evaluations can be performed on a RCM) Failure costs and Downtime Costs are calculated as sums of the lower level costs. If risk evaluations are NOT being performed, downtime and failure costs can be entered directly on the FM itself, they are not sums in this case.
You or the customer has to know if they are using evaluations and populate the appropriate fields on the DL. I don't know what happens if evaluations are being used, and downtime and failure costs are entered on the DL and the value is different than the sum. Safest approach is to enter values equal to the summation
