Functionality
This function module reads all log data for the specified object andsub-object from the local memory that at least has the specified logclass.
The data is transferred to the calling program in four internal tables(log header data, log parameters, messages, message parameters). Thenumber of read logs is also returned.
The function module also has the optional table parameterMESSAGE_PREPARED and an optional import parameterLANGUAGE. If both parameters are set when called the formattedmessages are transferred in this table. The message variables arealready inserted in the text.
The optional table parameter T_EXCEPTIONS (exceptions) returnsthe exceptions that are contained in the log. If the optionalparameters T_PREPARED_EXC and LANGUAGE are set, theformatted exceptions are transferred in the tableT_PREPARED_EXC.

Notes

• You can use the function module
APPL_LOG_DISPLAY_INTERN to displaylogs from the local memory.

• Use the function module APPL_LOG_READ_DB to
read logs from the database.

• To write text module texts for log headers or messages from the local
memory to internal tables, use the function moduleAPPL_LOG_READ_INTERN_LONGTEXT.
