Function module to check if a file is already open

[Former Member]

Hi All,

Could any one of you tell me a function module which checks whether a given file on the application server is currently being open or not.

Try to open the dataset in write mode.

If it fails, that means it is already open.

catch the Catchable Exception

CX_SY_FILE_OPEN

after the open dataset statement

Cause: File is already open (only in Unicode programs)

Hi Ravi,

Actually the scenario is something like this.

If the file is open in read mode then anybody can open it in write mode, in that case it won't give any error.

All I need to check is, if the file is open at all. Mode is not important in my situation.

Hi Amit Mishra,

1. There is no such FM/facility

by which we can know such thing.

2. However,

when we open the file in program,

the sy-subrc returned

tells that some error has occured,

and based on the value,

we can know, if its already opened!

Hi,

try to open the dataset it will fail to open and throw this CX_SY_FILE_OPEN .

the check the documentation..

Applying OPEN DATASET to a file already opened - in the same internal mode - triggers an exception of the type CX_SY_FILE_OPEN.

check the documentation on open dataset..

[hymavathi_oruganti]

if with open data set, sy-subrc = 4, then file is already open

use the FM FILE_OPEN

hi amit,

when we use open dataset....instruction you can make use of the exception CX_SY_FILE_OPEN to see if the file open provided it is opened in unicode mode.

Hi,

you can try FM <b>EPS_OPEN_INPUT_FILE</b> and check .

or FM's <b>RZL_READ_FILE_LOCAL</b>

check the sy-subrc and decide

Amit,

Try GET DATASET.

Basic form

GET DATASET dsn.

Extras:

1. ... POSITION pos

2. ... ATTRIBUTES attr

In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. For details, see File Interface.

Effect

Used to get the properties of a file already open.

You can use this statement without additions to determine whether the file is open.

If the file is not open, an exception of the type CX_SY_FILE_OPEN_MODE is triggered.
