Hello

I have a question with regards to the EPBCS FDM tool. I am currently doing an implementation and the client will normally use only the PBCS (Standard Application).
So basically, they already have the budget for five years and this data must be loaded on PBCS. Then data forms and reports can be created.
This data will also be loaded on Fusion Financials.

My questions are:
1. What can we exactly do with the FDM tool? It is not very clear for me from the training videos.
2. Can we simply load the data on Fusion Financials, and then use the FDM tool to send the data to the cube Plan1?
3. In what case would we write back data to Fusion Financials?
4. Is this integration needed for reports on Financial Reporting Studio to work on Fusion?

Thank you to advise as I am a bit confused.
