Read a file with a variable=counter : NAMEFILE001,NAMEFILE002..

Posted on Feb 22, 2005 at 10:30 AM 13 Views

Hello,

I would need your councils.

I can read a logical file on my server(logical example of name: NAMEFILE) with function FILE_GET_NAME.

But I would like to be able to read a file with a counter i.e.

the first time: to read NAMEFILE001;

the second time read NAMEFILE002;

the third time read NAMEFILER003...

How made you that?

With function FILENAME_EXIT _?

But, where do I put the variable = counter? In a table...?

Thank you in advance of your answer

Servane

    Hello Servane,

    What I understood from your description is that you want to call the Function FILE_GET_NAME multiple number of times. Is that correct? If yes, then look at the following code :

    DATA : W_LOGICAL_FILENAME TYPE FILEINTERN,
       W_FILENUMBER(3)    TYPE N.

DO 10 TIMES.
  MOVE SY-INDEX TO W_FILENUMBER.
  CONCATENATE 'TESTFILE'
              W_FILENUMBER
         INTO W_LOGICAL_FILENAME.
  CALL FUNCTION 'FILE_GET_NAME'
     EXPORTING
        LOGICAL_FILENAME = W_LOGICAL_FILENAME
     IMPORTING
        FILE_NAME = FILE
        FILE_FORMAT = FORMAT.
ENDDO.

    Does that answer your question ? If yes, then please close the thread. Otherwise, get back with the problem.

      Hi Servane,

      You could also do the following:

      in transaction FILE you set up the physical path name as follows:

      /<i>path</i>/.../<FILENAME><PARAM_1>

      then you call the function FILE_GET_NAME:

        CALL FUNCTION 'FILE_GET_NAME'
       EXPORTING
         LOGICAL_FILENAME        = W_LOGICAL_FILENAME
         PARAMETER_1             = W_FILENUMBER
      IMPORTING
           FILE_NAME               = THEFILE
       EXCEPTIONS
            FILE_NOT_FOUND          = 1
            OTHERS                  = 2.

      This will equally construct the name/counter as you wish.

      AND, if I am not wrong, since the system does it, you will not have to worry about putting the last counter value away in the DB.

      cheers,

      Phil
