Despite these challenges, SAP BSCE has put efforts into trying to overcome these problems. At the end of the Thesis, as per analysis of SAP financial results of business activities during the crisis, it is proven the setting up a shared service centre was a good decision of SAP and it paid off with the contribution to help SAP overcome the impacts of crisis.
