What are SAP industry solutions?

Companies can supplement SAP ECC with industry solutions. SAP labels these solutions with the addition IS for "Industry Solutions". For example, there are special solutions for banks (IS Banking), the automotive industry (IS Automotive), or retail (IS Retail). Various types of industry solutions are available within SAP ECC: as a central component of SAP ECC (no additional components required), as a business function set (no activation of additional components required), as an enterprise extension or enterprise business function, and as an add-on (separate installation). The majority of the industry solutions can be activated by using the Industry Business Function Sets. In this way, SAP ECC can be easily adapted to the requirements of the industry solution.
