Function module help

Former Member — Wed, 27 Feb 2008 05:19:25 GMT

Hi abapers,

I have 3 queries

1) I hv a parameter Filename.When i press f4 help the path of the application server should be displayed. Is there any function module?

2) When i manually enter the path say E:\usr\sap\file1.txt then it should check whether the path E:\usr\sap\ exist or not in the application server irrespective of the file name.

Also is there any function module where i can separate the directory and file name?

3) Suppose if i enter any any special characters say * or / or : etc it should also give an error message tht special characters are not allowed. is there any way for that?

thanks in advance,

Regards

Salish

Hi,

1.Use FILE_GET_NAME function module. U can get the application server path. Pass client = sy-mandt, logical filename, operating system = sy-opsys.

2.You can use SPLIT command to separate the path .

Ex: SPLIT filename at '/' into gwa_input-var1 gwa_input-var2.... This way, the last variable will give u the filename.

3.The above functional module will automatically give u the physical location of the file. So, no need for this validation.

Hope this helps.

Ramya

Point 1:

Here you can use F4_FILENAME_SERVER function module

2) When i manually enter the path say E:\usr\sap\file1.txt then it should check whether the path E:\usr\sap exist or not in the application server irrespective of the file name.

Also is there any function module where i can separate the directory and file name?

Point 3:

Here you can perform the following syntax:

IF v_filename CA '*/%'.

MESSAGE e002(sy) with 'Filename contains special characters'.

ENDIF.

Hi,

1) To provide F4 help for the application server, you can use the FM 'F4_DXFILENAME_TOPRECURSION'.

Ex:

v_l_path = '/TECHDATA/INTERFACES/IN/FIN/'.

In case Unix Server Radio button is checked

CALL FUNCTION 'F4_DXFILENAME_TOPRECURSION'

EXPORTING

i_location_flag = 'A'

i_server = ' '

i_path = v_l_path

filemask = '*'

FILEOPERATION = 'R'

IMPORTING

O_LOCATION_FLAG =
O_SERVER =

o_path = v_l_file

ABEND_FLAG =

EXCEPTIONS

rfc_error = 1

error_with_gui = 2

OTHERS = 3.

2) You can use following code for validation.

OPEN DATASET <File Path> FOR INPUT IN TEXT MODE ENCODING DEFAULT.

IF sy-subrc NE 0.

Message

ENDIF.

3) you can use SEARCH FOR command to check for the special characters in the path.

Solution 1:

Use F4_FILENAME_SERVER function module or yppu can also use FM FILE_GET_NAME

Solution 2:

Taking into account the filename provided by you as E:\usr\sap\file1.txt.

Split Filename at '\' into var1,

var2,

var3.

* To get the Directory Name

Concatenate var1 var2 into v_directory

var3 contains your Filename.

Solution 3:

IF filename CA '*/%'.

Message for Invalid Filename.

ENDIF.

Reward Points if you find it useful.

Hi ,

For the third solution.

You neeed to check for special characters in the Filename only.

after splitting, catch the filename in a variable v_filename.

IF v_filename CA '/%'.*

Message for Invalid Filename.

ENDIF.

Thanks for all of ur replies.

But the directory can be many u cannot use split.

Is there any fonction module tht can separate the filename and the directory name.

Thanks

Hi Salish,
