Even though SAP has more than 10,000 standard transactions, all companies create their own custom ones. There are different reasons for building custom transactions. For example, a user might need a specific report, a list, or a functionality that isn't in the system. Sometimes there are even cases where custom transactions with identical functionality of an existing standard transaction are created. Creating custom transactions isn't a problem, it is a normal usage of the system.
SAP is a complex and ever changing system, whether because of changes introduced to your SAP implementation to better suit your business, or through the application of Security Notes (Patches) to ensure that newly disclosed vulnerabilities are mitigated. In order to provide a predictable and scheduled flow of vulnerability mitigation information and security patches, SAP releases the major part of their latest Security Notes information on the second Tuesday of every month.
