Here is a list of important Function Modules in SAP.Function modules are re-usable programs ( codes ) that can be called via ABAP programs.

Function ModuleDescription
ABAP_DOCU_DOWNLOADDownload ABAP documentation in HTML format.
APPL_LOG_DELETEWith this function module you delete logs in the database according to specified selection conditions
APPL_LOG_DISPLAYWith this function module you can analyze logs in the database.
APPL_LOG_DISPLAY_INTERNWith this function module you can analyze logs in local memory, e.g. when you have only collected log records at runtime and do not want to write to the database.
APPL_LOG_INITThis function module checks whether the specified object or sub-object exists and deletes all existing associated data in local memory.
APPL_LOG_READ_DBWith this function module you read the log data in the database for an object or sub-object according to specified selection conditions.
APPL_LOG_READ_INTERNWith this function module you read all log data whose log class has at least the specified value, from local memory, for the specified object or sub-object.
APPL_LOG_SET_OBJECTWith this function module, you create a new object or sub-object for writing in local memory.

With a flag you can control whether the APPL_LOG_WRITE_… messages are written in local memory or are output on the screen.

APPL_LOG_WRITE_DBWith this function module you write all data for the specified object or sub-object in local memory to the database.

If the log for the object or sub-object in question is new, the log number is returned to the calling program.

APPL_LOG_WRITE_HEADERWith this function module, you write the log header data in local memory.
APPL_LOG_WRITE_LOG_PARAMETERSWith this function module, you write the name of the log parameters and the associated values for the specified object or sub-object in local memory.

If this function module is called repeatedly for the same object or sub-object, the existing parameters are updated accordingly. If you do not specify an object or sub-object with the call, the most recently used is assumed.

APPL_LOG_WRITE_MESSAGE_PARAMSWith this function module you write a single message, with parameters, in local memory. Otherwise the function module works like APPL_LOG_WRITE_SINGLE_MESSAGE.
APPL_LOG_WRITE_MESSAGESWith this function module you write one or more messages, without parameters, in local memory.
APPL_LOG_WRITE_SINGLE_MESSAGEWith this function module you write a single message, without parameters, in local memory.

If no header entry has yet been written for the object or sub-object, it is created. If you do not specify an object or sub-object with the call, the most recently used is assumed.
