How can we adjust Fx for Cash Flow

Need to do adjustment to Fx for Cash Flow

Content

Hi,

We have a client that quarterly adjusts their Fx line for cash flow due to intercompany remeasurements and immaterial variance plugging. Since  FCCS_FX_Total_NonCash is a calculated member, how can we adjust Fx for cash flow? We can't move this member even thought the scissor icon is available but once we moved, it breaks the app. We tested. The scissor icon should be grayed out. Can we add a rollup for Fx under FCCS_CashFlow? I was thinking something below. Would it work if we share  FCCS_FX_Total_NonCash, a dynamic calc member? Any suggestions would be appreciated. Or Oracle should add a manual
