According to Oracle documentation1, you should do the following things when you are implementing a multipillar implementation of both HCM Cloud and ERP Cloud: Deploy your chart of accounts, use HCM's Enterprise Structure Configurator (ESC) first, and use file-based spreadsheet loaders using UCM to mass load and maintain chart of accounts segment values and hierarchies. Therefore, options A, B, and D are correct. Option C is incorrect because you should create your chart of accounts in the following order: value sets, COA structure instance, and then assign values to the value sets. Option E is incorrect because you should use the Rapid Implementation spreadsheet when creating your chart of accounts, not your enterprise structure.
