Application server file path vaidation

Former Member — Fri, 27 Jun 2008 04:31:41 GMT

I have written the code for application server file path validation.

DATA : l_fname TYPE filename-fileintern." type c.

DATA : l_filpath TYPE filename-fileintern,

l_filname(40) TYPE c.

PARAMETER : p_sucfil LIKE rfpdo-rfbifile OBLIGATORY. " rlgrap-filename

AT SELECTION-SCREEN ON p_sucfil.

l_fname = p_sucfil.

CALL FUNCTION 'FILE_GET_NAME'

EXPORTING

CLIENT = SY-MANDT

logical_filename = l_fname

OPERATING_SYSTEM = SY-OPSYS

PARAMETER_1 = ' '
PARAMETER_2 = ' '
PARAMETER_3 = ' '
USE_PRESENTATION_SERVER = ' '

WITH_FILE_EXTENSION = 'X'

USE_BUFFER = ' '
ELEMINATE_BLANKS = 'X'

IMPORTING

EMERGENCY_FLAG =
FILE_FORMAT =

FILE_NAME = l_filpath

EXCEPTIONS

FILE_NOT_FOUND = 1

OTHERS = 2

IF sy-subrc <> 0.

message 'Invalid file name' type 'E'.

ENDIF.

But always i will get Invalid file name.

Y is it so.

pls help me.

Hi,

Is a file with that name present on the address you are passing to

CALL FUNCTION 'FILE_GET_NAME'

Hi Praveen,

Check condition for issuing the message.

If it IF SY-SUBRC EQ 0, change it to IF SY-SUBRC NE 0.

That means you are issuing error message when it is successful.

If thats not the issue, let me know.

Hope this helps you. Reward points if satisfied.

Any queries, get back to me.

Hi,

Sy-subrc i am getting is equal to 1.

Always it is 1.

Re: Application server file path vaidation

nikhil_chitre — Fri, 27 Jun 2008 04:49:05 GMT

well Pointed out by Chandra Shekar.

you seem to be checking If Sy-Subrc = 0.

for message display.

Check your code.

Hi Nikhil,

I am checking for

sy-subrc <> 0.

FM return sy-subrc eq 1.

I does not know y.

File path is correct and file exist on application server

Re: Application server file path vaidation

nikhil_chitre — Fri, 27 Jun 2008 04:55:00 GMT

what is File type?

Re: Application server file path vaidation

Former Member — Fri, 27 Jun 2008 04:57:24 GMT

/tmp/zptest01.txt

is the file on application server.

Re: Application server file path vaidation

Former Member — Fri, 27 Jun 2008 04:58:19 GMT

Hi Praveen,

I could not get you. What do you mean by SY-SUBRC 0. Is it EQ to zero of NE 0.

Make sure that it is either EQ or NE. Here it must be NE, as per your code.

If it is SY-SUBRC NE 0, it does not give the message.

Let me know, what happened.

Hope this helps you.

Any queries, get back to me.

FM FILE_GET_NAME Assigns the Physical File Name Using a Logical File Name. And mapping between Logical File Name and Physical File Name is maintained in transaction FILE.May be the logical file name u r giving as input against it no Physical File is not maintained in tran. FILE. Pl. check.

Joy.

Hi Chandrashekar / Joyjit,

Sy-SUBRC NE 0.

Joyjit,

I checked in FILE Tcode.

Logical file name in thei tcode TMP is also maintained.

still ia m agetting this error.

One more thing, if file doesn't exists. i may give us error right.

What can we do for this.

vinod_vemuru2 — Fri, 27 Jun 2008 05:26:01 GMT

Hi Praveen,

First thing is application server file is case sensitive. So declare ur selection screen parameter with Addition LOWER CASE.

PARAMETER : p_sucfil LIKE rfpdo-rfbifile OBLIGATORY LOWER CASE.

Second use FM PFL_CHECK_OS_FILE_EXISTENCE which perfectly working fine for application server file validation. Here also file name is case sensitive. Check this FM in SE37 by giving ur file name and check the check box Lower case. Revert if it is not clear.

Thanks,

Vinod.

Former Member — Fri, 27 Jun 2008 05:26:25 GMT

So u mean to say in File tran. TMP is ur logical file name and /tmp/zptest01.txt is ur physical file name..right?

And as input u r giving TMP but u r getting error from FM FILE_GET_NAME.

Pl. confirm.

Joy.

Hi Praveen,

Look at the FILE_NAME = l_filpath, you are passing in IMPORT parameters.

I think it must be ' l_fname' , in which you have the path.

Hope this helps you.

Any queries, get back to me.

Hi ur problem can be a bit reduced using f4 help for the application server input path

Use the function module '/SAPDMC/LSM_F4_SERVER_FILE' for F4 help for

Application server files. you need to write this in the

AT SELECTION_SCREEN on FIELD REQUEST.

using this you will make sure the user enters a valid path..

Hi Vinod,

This Fm PFL_CHECK_OS_FILE_EXISTENCE is working fine.

You mean to say that when user provides file path on selection screen. File should be present already in the path that user provided on selection screen.

and Chandrashekar,

In import

FILE_NAME = l_fname.

Still i am getting error.

Re: Application server file path vaidation

Former Member — Fri, 27 Jun 2008 06:09:29 GMT

FILE_GET_NAME - gives the physical path for the logical file NAME.

Go to transaction FILE. Click the LOGICAL FILE NAME DEFINITION, CROSS Client

Make sure you specify the file name and not the file path. If the file name does not exist, the function module will give error that file not found.

If you have complete physical file name then you may also validate it :

data: Dsn(200) value <Complete physical file name>.

Open dataset dsn for INPUT in binary mode.

if sy-subrc <> 0.

Error - file not found

else.

file Exists.

endif.

Reward if useful.

Praveen,

I have checked ur code and I found that if i give a logical file name from

tran. FILE under folder 'Logical file name definition, cross client' then ur code works. Pl. check.

Joy.

Hi Joyjit,

If logical file path doesnot exists in FILE tcode,

then i need to create that.

its long process to get created.

I am using now Open dataset for the same.
