As part of this work, we are switching to a new Set of Books/Chart of Accounts.

Oracle Consulting is currently in the process of implementing Fusion.
As part of this initiative, we are transitioning to a new Set of Books/Chart of Accounts.

We need your assistance in exploring whether there is an alternative way to resolve this issue without changing the BU. If not, and changing the BU is the only solution, then we will need to make this change for approximately 4,000 employees. In that case, is there an HDL/HSDL option available to achieve this?

Could you please suggest how this update can be handled through HDL, and if possible, share any sample files for reference?
