Easy filtering is enabled for all fields in the grid, for which
filtering is supported, regardless the number of fields and the number of
records.
Note
If a user filters on a non-index field, LN performs a full
table scan. This can cause performance problems, if a table contains many
records.
All Fields till Runtime Count Limit
The filtering depends on the count limit specified in the Count field in the Maintain Parameters (ttaad0100m000) session:
If the number of records in the overview session's main table
is less than or equal to the count limit, easy filtering is enabled for all
fields in the grid, for which filtering is supported.
If the number of records in the table is greater than the count
limit, easy filtering is only enabled for index fields in the grid. In this
way, full table scans on tables with many records are prevented.
Table Index Fields
Easy filtering is only enabled for index fields in the grid. In
this way, full table scans are prevented.
