Following the rapidly changing business needs and technological changes, SAP now offers a number of R / 3 switchable or even independent products in addition to the well-known R / 3 system. An example is LSO (Learning  Solution) distance learning and examination system, SAP portal, WEB-shop, or even BI and CRM.

         To protect business data, many large companies have strict internal policies that prohibit access to the company’s internal network from the outside. The rule is understandable and useful, but it makes it impossible for systems that are not of excessive business importance to be accessible from the outside. This measure can prevent users from logging in from anywhere to perform their own activities, even in large numbers, independently of different activities that are useful to the company. (e.g. training, examinations, career development).
        It can also be a problem that a company would like to take advantage of innovative features but does not have the in-house knowledge and experience to set up and operate the system, or simply lacks the budget for it.
