The life of an application does not end once development is complete. Over time, the business requirements may change or users may request additional functionality. These application updates can be accomplished easily by applying the same principles and procedures that have been discussed so far.
For example, if you change the length of a field,CA 2E automatically modifies all files and functions that use the changed field, including associated panels and reports. You will need to examine the panel and report designs to ensure that they have not exceeded their limits, and then regenerate the files and functions. The Submit model create process provides options to save data prior to generation and compile.
To aid you in managing changes and identifying the impact of a change on your model,CA 2E provides a set of powerful tools that are the subject of the rest of this chapter.
