SAP Business Warehouse could have been better. There is room for improvement from a technical perspective. So, from a technical perspective, when we are upgrading a Business Warehouse server or we are migrating from one place to another, the capability required for this upgradation has many manual activities. It took us around a month to streamline our server. Let’s say there are some transaction codes. Transaction code is a set of programs, and when you want to run a program from the backend, you need to hit the transaction code. It is called a T-code. So during the upgrade, many transaction codes get affected, and as a security consultant, it is my responsibility to recheck those transaction codes which are affected. Sometimes more than 100 codes may get affected, sometimes 500, and sometimes more as well. So, it takes a hell lot of time to integrate them again. That is a limitation or defect within the SAP Business Warehouse. SAP Business Warehouse should come up with proper solutions. Upgradation is an automatic activity. It should happen by itself. We just need to initiate it, and the backend SAP server is automatically upgraded. But it should handle the transactional code as well. They should not get absolutely, and any authorization object should not get deleted from the transaction codes. So, that functionality SAP Business Warehouse should come up with.
