Onhand Conversion with FIFO cost

Summary

Convert onhand Data from EBS to Cloud, with FIFO cost

Content

Hello there, 

I have a customer who is a manufacturer of high-tech equipment. The customer uses FIFO costing in EBS with cost under different elements and element types, as shown below, depending on the item type. Some of the subassemblies have all 5 components of cost; Buy items have material cost and material overhead . What is the best way to bring the cost into cloud under all these elements. FBDI template for inventory transactions doesn't seem to support it at element level. REST APIs documentation doesn't say anything. 

Thanks for your help.
