Integrating project planning software with business planning systems (ERP)

Hello there

I have been trying to obtain information about "integrating project planning systems with business planning systems (ERP, PLM)" but I could not find any proper source. Would you help me out on this?

I would like to focus on what benefits can be expected from a close integration of project planning

tools and enterprise information systems such as ERP and what evidence is there that

this is being exploited. If you can help me out with proper sources, I would be appreciated.

Best Regards
