We are implementing Oracle Projects (Costing and Billing) but AR is already implemented and using since long. We are migrating Revenue and Invoice data for open projects.
For revenue migration: we are uploading summarized cost and generating revenue and will reverse the entry in GL.
For Billing : We are entering one billing event per project and generating Invoice and then interfacing it to AR. In AR, we are making invoice Incomplete and then deleting the invoice from AR transaction form. We want to understand, is this the correct approach & can there be issues in future?
