how i can get the sap (application server side) root dir (function module)?

[Former Member]

hi,

i need to get the sap root installation folder (for ex: "C:\MiniWAS")

is there any function modules ?

for sap gui directory i use:

"

DATA PS_WORKDIR TYPE STRING.

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GET_SAPGUI_DIRECTORY

CHANGING

SAPGUI_DIRECTORY = PS_WORKDIR.

"

but i need also the root path of the SAP application server too!

thanks in advice

Hi Michele,

Refer url

Check FM SUBST_GET_FILE_LIST By passing DIRNAME and FILENM as *, you can see the list of files in that directory.

Hope this helps

@ moazam hai

thanks for the quick answers ( i known the RZL_* class..)...

anyway

why i must use function modules that list files and let consider the sap root folder as implicit

(i need to extract it!!...)?

why waste resources building a table extracting paths cutting filenames , etc... (because i list files..

instead simply get the physical SAP root path!) ??

there isn't a function module as:

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GET_SAPGUI_DIRECTORY

that simply return into a string (as GET_SAPGUI_DIRECTORY do..) the correct installation path of SAP?

Thanks

forget to paste (could be usefull ..)

my solution to this lack of sap function modules..:

* assume sap home for ex. "C:\MiniWAS\" as implicit

DATA AS_FSYSTEM_SEPARATOR type C
VALUE '\'.



DATA AS_GET_TRIDEDSK_CMD_file type string
VALUE 'gethome.cmd'.

DATA AS_GET_TRIDEDSK_TMP_file type string
VALUE 'TRIDEDSK.tAS'.

DATA: BEGIN OF AS_TRIDEDSKREC,
        PATH(256) type C,
      END OF AS_TRIDEDSKREC.

DATA AS_TRIDEDSK_path type string.

* TOOL AS GET AS_TRIDEDSK_path ---------BEGIN


CONCATENATE AS_GET_TRIDEDSK_CMD_file INTO
AS_GET_TRIDEDSK_CMD_file SEPARATED BY AS_FSYSTEM_SEPARATOR.

CONCATENATE AS_GET_TRIDEDSK_CMD_file AS_GET_TRIDEDSK_TMP_file INTO
AS_GET_TRIDEDSK_CMD_file SEPARATED BY ' '.


OPEN DATASET AS_GET_TRIDEDSK_TMP_file FOR OUTPUT
IN TEXT MODE ENCODING DEFAULT.
CLOSE DATASET AS_GET_TRIDEDSK_TMP_file.


* FILTER[1]: this file must exist (needed by the filter option)
Open Dataset AS_GET_TRIDEDSK_TMP_file for input
     in text mode
     encoding default
filter AS_GET_TRIDEDSK_CMD_file.

CLOSE DATASET AS_GET_TRIDEDSK_TMP_file.


* FILTER[2]: read the result of the system command "echo"
Open Dataset AS_GET_TRIDEDSK_TMP_file for input
     in text mode
     encoding default.

DO.
  READ DATASET AS_GET_TRIDEDSK_TMP_file INTO AS_TRIDEDSKREC.
  IF SY-SUBRC NE 0.
    EXIT.
  ELSE.
    AS_TRIDEDSK_path = AS_TRIDEDSKREC-PATH.
  ENDIF.
ENDDO.

CLOSE DATASET AS_GET_TRIDEDSK_TMP_file.


* TOOL AS GET AS_TRIDEDSK_path -----------END

this is an example of the "gethomecmd.cmd"

called by sap (retreive the full path of sap root),

save it under the SAP ROOT (for ex. "C:\MiniWAS")

gethomecmd.cmd
