SAP integration

Need support to understand the possible connections between FAS and SAP (SAP would be the source of info - new assets, retirement, add value and impairment - that would send data to FAS individual assets. In the other hand FAS would send couple financial info like due tax and similar). With this approach we would end with SAP being responsible for the financial portion and FAS for tax. 

What are the possible solution?

What is the recommendation from SAGE?
