I have a ztable. This is also maintained using sm30. Now I have modified the table to add some new fields. In sm30 I want to maintain values for this new fields. The condition is I don't want to lose the values that were prevously maintained for the other fields. Is there anyway this can be achieved.
While in table maintenance generator during modification, tick on the screens so that they are deleted and regenerated again otherwise changes will not get reflected in your screen of table maintenance.
