How to Determine the Cost of Work in Progress Item after We get the COGS of Finished Goods

*Work in Progress Item = WIP
*Finished Goods = FG



  1. WIP A = material + labor + etc
  2. WIP B = WIP A + material
  3. FG Y = WIP B + material
  4. FG Z = WIP B + material

One Production WIP B can be use for FG Y & FG Z

Is there any concern or finding process data or report in 365 so I can get the cost of WIP A for only FG Y?
