ways to know if a table content has been updated

[alisa m]

how can I know if the content of a SAP standard table has been changed?
that is, aside from logging the changes in the technical settings of the table;
we have 14 standard transparent tables and some of them are big: logging them would slow down the system.
I do not need to know WHAT has been changed but only IF.
thanks

All depends whether these tables have a change date as one of there fields, is it possible to provide me with an example table to look into for you further!

table PLKO for instance: but the point is I want to avoid having to check records; these are tables that change seldom but, when they do, i must know it!
i want to avoid the log because it is too heavy and, since most of the times records do not change, if I check dates the system will check every record.
there are 14 tables, most of them with 100.000+records....
