Hi,
You can try doing this:
i. Send the data into Entity = Entity_None, with all the Cost Centres mapped accordingly, and with AuditID = 10_Input
ii. Create a logic to copy the data above to Entity = CostCentre.Entity, and with AuditID = 11_Input
Having said that, i don't think the Transformation and Conversion Files do not look at attributes or properties.
Regards
