Chapter 17: Change ManagementChange Control (Managing Transports)Change control is the process of managing changes, modifications and customizing made tothe system and the transport of those changes through the pipeline from the development tothe test system, and finally to the production system. One of the most important changemanagement tasks involves notifying the appropriate people of the changes and gettingtheir approvals.Because R/3 is an integrated system, there are items that may impact many other modulesor groups. If, for example, a change is made to a module which impacts other modules, andthis change is done without the knowledge of the appropriate people, a process may ceaseto function. If something stops functioning in the production system, business may stopuntil the problem is resolved.In the past, most application systems were independent, so changes in one system wereinsulated from the other systems. Because of this independence, users may not be used toconsulting with other organizations when making changes to what they consider “their”systems.In change control, there is a review and approval process. You should not make a changeand apply it to the system without a review and approval of the changes. These changesapply to changes to SAP objects and system configuration.The following steps demonstrate a change control process:1. Document all code, configuration, and other changes.2. Test by: Developer Functional analyst3. Get the following signoffs (see sample Transport Request Form on page 14)By all functional groups: Review and be aware of changes that might affect their functional areas. If needed, perform additional tests by and with other functional groups, where thereis possible interaction from the change.17–12Release 4.6A/B
Chapter 17: Change ManagementChange Control (Managing Transports)Operations review Review any changes that may affect the operations staff Schedule new jobs Program error or problem procedureDocument the program restart procedure. Is it “safe” for the operator to restart thejob, if it fails or hangs?4. Verify the change in the target systemChange control should also contain a recovery plan that includes: What to do if the import to the production system creates a problem? How to roll back? Will it be possible to roll back? Will a problem require a database restore?A transport cannot be “undone.”System Administration Made Easy17–13
