Hello,
there aren't as such best practice for JVA. But before I would to understand some setup in your system.
- When you have mentioned ERP6.0, have you also activated NewGL?
- Is rollout from scratch or do you using an existing setup?
- Do you have the business scope of your processes? Actually from country to country, you have to customize the JVA module / activate the processes in the different way.
