Using this logpoint parameter, you can specify a list of ABAP data objects, except literals, that are valid at the current source code position at runtime. The particular ABAP data objects in the list have to be separated by a SPACE or comma.
According to the FIELDS addition of the (static) LOG-POINT statement in ABAP, the Field Values in dynamic logpoints are used in log results. One or multiple Field Values in dynamic logpoints are written for each aggregated log entry.
A log entry is only updated for a logpoint event with identical Key Definition. Otherwise, if the Key Definition of the log event differs from the previous one, a new log entry is created.

In contrast to the Key Definition, you can also specify internal tables and deep structures as data objects for Field Values. In addition, you can add special built-in functions to the results list. Each built-in function has a specific return value that is added to the log results.
