Maintaining and changing an existing maintenance dialog

Use

There are two possible reasons for changing an existing maintenance dialog:

for technical reasons e.g table or view changes (addition or deletion of fields).
for application reasons, e.g. additional input data consistency check logic required. Types of changes:

maintenance screens (layout and flow logic)
interface
events in program flow

User program code can only be included via user includes. The includes must be created manually in the function group.

Dialog changes must be made such that regeneration does not lose modifications. You can use the Generate table maintenance dialog tool to regenerate selectively, i.e. to replace only the necessary dialog components. If you have changed maintenance screens, the interface or the main program, you should exclude them from the regeneration. Maintenance does not affect events.
