APPL_LOG_DELETE	With this function module you delete logs in the database according to specified selection conditions
APPL_LOG_DISPLAY	With this function module you can analyze logs in the database.
APPL_LOG_DISPLAY_INTERN	With 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_INIT	This function module checks whether the specified object or sub-object exists and deletes all existing associated data in local memory.
APPL_LOG_READ_DB	With 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_INTERN	With 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_OBJECT	With 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_DB	With 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_HEADER	With this function module, you write the log header data in local memory.
APPL_LOG_WRITE_LOG_PARAMETERS	With 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_PARAMS	With 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_MESSAGES	With this function module you write one or more messages, without parameters, in local memory.
APPL_LOG_WRITE_SINGLE_MESSAGE	With 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.

ENQUE_SLEEP	Wait a specified period of time before continuing processing.
ENQUEUE_ESFUNCTION	Lock an abap program so that it cannot be executed.
Example:  Set the parameters as follows:  RELID = 'ZZ'  SRTF2 = 0  SRTF = (your report name)
Please note that you should not use SY-REPID to pass your report name to the function. The value of SY-REPID will change as it is being passed to the function module, and will no longer hold the value of the calling report.

FILENAME_GET	popup to get a filename from a user, returns blank filename if user selects cancel
FORMAT_MESSAGE	Takes a message id and number, and puts it into a variable. Works better than WRITE_MESSAGE, since some messages use $ as a place holder, and WRITE_MESSAGE does not accommadate that, it only replaces the ampersands (&) in the message.
FTP_COMMAND	Execute a command on the FTP server
FTP_CONNECT	Open a connection (and log in) to an FTP server
FTP_DISCONNECT	Close the connection (and log off) the FTP server
FU CSAP_MAT_BOM_READ	You can use this function module to display simple material BOMs. You cannot display BOM groups (for example, all variants of a variant BOM). as in transaction CS03. Current restrictions: You cannot display long texts. You cannot display sub-items. You cannot display classification data of BOM items for batches. You can only display one alternative or variant. You cannot enter an alternative for module CSAP_MAT_BOM_READ, so you always see alternative 01. The following example came from a posting on the SAP-R3-L mailing list.
Example:  data: begin of tstk2 occurs 0.  include structure stko_api02.  data: end of tstk2.  data: begin of tstp2 occurs 0.  include structure stpo_api02.  data: end of tstp2.  data: begin of tdep_data occurs 0.  include structure csdep_data.  data: end of tdep_data.  data: begin of tdep_descr occurs 0.  include structure csdep_descr.  data: end of tdep_descr.  data: begin of tdep_source occurs 0.  include structure csdep_source.  data: end of tdep_source.  data: begin of tdep_order occurs 0.  include structure csdep_order.  data: end of tdep_order.  data: begin of tdep_doc occurs 0.  include structure csdep_doc.  data: end of tdep_doc.  data: flg_warning like capiflag-flwarning.  call function 'CSAP_MAT_BOM_READ'  exporting  material = 'MAT100'  plant = '0001'  bom_usage = '1'  valid_from = '20.12.1996' valid_to  importing  fl_warning = flg_warning  tables  t_stko = tstk2  t_stpo = tstp2  t_dep_data = tdep_data  t_dep_descr = tdep_descr  t_dep_source = tdep_source  t_dep_order = tdep_order  t_dep_doc = tdep_doc  exceptions  error = 1.

HELP_VALUES_GET_WITH_TABLE	Show a list of possible values for F4 popup help on selection screens. This function module pops up a screen that is just like all the other F4 helps, so it looks like the rest of the SAP system. Very useful for providing dropdowns on fields that do not have them predefined.
Example:  tables: t001w.  DATA: lc_werks LIKE t001w-werks,  ltab_fields LIKE help_value OCCURS 0 with header line,  BEGIN OF ltab_values OCCURS 0,  feld(40) TYPE c,  END OF ltab_values. *- *-- Set up fields to retrieve data  ltab_fields-tabname = 'T001W'.  ltab_fields-fieldname = 'WERKS'.  ltab_fields-selectflag = 'X'.  APPEND ltab_fields.  ltab_fields-tabname = 'T001W'.  ltab_fields-fieldname = 'NAME1'.  ltab_fields-selectflag = space.  APPEND ltab_fields. *-- Fill values  select * from t001w.  ltab_values-feld = t001w-werks.  append ltab_values.  ltab_values-feld = t001w-name1.  append ltab_values.  endselect.  CALL FUNCTION 'HELP_VALUES_GET_WITH_TABLE'  EXPORTING  fieldname = 'WERKS'  tabname = 'T001W'  title_in_values_list = 'Select a value'  IMPORTING  select_value = lc_werks  TABLES  fields = ltab_fields  valuetab = ltab_values  EXCEPTIONS  field_not_in_ddic = 01  more_then_one_selectfield = 02  no_selectfield = 03.
HOLIDAY_CHECK_AND_GET_INFO	Useful for determining whether or not a date is a holiday. Give the function a date, and a holiday calendar, and you can determine if the date is a holiday by checking the parameter HOLIDAY_FOUND.
Example:  data: ld_date like scal-datum default sy-datum,  lc_holiday_cal_id like scal-hcalid default 'CA',  ltab_holiday_attributes like thol occurs 0 with header line,  lc_holiday_found like scal-indicator.  CALL FUNCTION 'HOLIDAY_CHECK_AND_GET_INFO'  EXPORTING  date = ld_date  holiday_calendar_id = lc_holiday_cal_id  WITH_HOLIDAY_ATTRIBUTES = 'X'  IMPORTING  HOLIDAY_FOUND = lc_holiday_found  tables  holiday_attributes = ltab_holiday_attributes  EXCEPTIONS  CALENDAR_BUFFER_NOT_LOADABLE = 1  DATE_AFTER_RANGE = 2  DATE_BEFORE_RANGE = 3  DATE_INVALID = 4  HOLIDAY_CALENDAR_ID_MISSING = 5  HOLIDAY_CALENDAR_NOT_FOUND = 6  OTHERS = 7.  if sy-subrc = 0 and  lc_holiday_found = 'X'.  write: / ld_date, 'is a holiday'.  else.  write: / ld_date, 'is not a holiday, or there was an error calling the function'.  endif.
