JD Edwards EnterpriseOne FDA Compare
The FDA Compare tool in Form Design Aid (FDA) enables you to compare one version of an application to another. You can compare them on the application level to determine whether forms have been added, deleted, or rearranged and whether the properties have changed. You also can compare the forms in the applications to each other to see whether controls have been added, deleted, or rearranged and whether the properties have changed.
Additionally, you can compare two different applications as well. This feature is useful when you have made a new application by copying an existing one and then modifying it. Then, when you upgrade, you can not only compare the base application to its new counterpart, but also you can compare a custom application.
