If you choose the F4 help in city or street maintenance or in address maintenance for a city or a street, it may take a very long time to display the screen for the further restriction of data.
The respective search helps (CITYA, CITY_NAME, STRTA, STRT_NAME) have dialog type 'A' (dialog depending on value set).In this case, some (101) entries are read before the decision whether to display the number of hits immediately or whether a dialog is required to limit the value set.
Although not many entries are read, the unselective reading via a view takes very long in some database systems.
The dialog type of the above-mentioned search helps is changed to 'C' (complex dialog with value restriction).
In IS-U and IS-T 1.2, the error is corrected with add-on Support Package 17. However, for technical reasons, the change of the search helps CITYA and STRTA is not delivered and has to be carried out manually (as modification), if required.
