Question:
I am on version 3.1I and trying to find a function that will validate if a path exists. In my selection screen I have a field that asks for the path and with this entry I will WS_DOWNLOAD a file to this path but before I do I would like to know if this path is valid. Can anybody help me on this.
Thanks!
Answer:
I can't remember whether WS_QUERY existed then, but if it does, you can use that.
Answer:
seven_of_nine, thank you for your reply. I've tried the function but I can't get in to work. Could you please give me an example of how to call it? Let's say that the path is C:\TEMP. How would I call the function to see if the path is valid.
Thanks for your help!
Answer:
DATA: g_return.
CALL FUNCTION 'WS_QUERY'
     EXPORTING
*         ENVIRONMENT    =
          filename       = 'C:\temp'
          query          = 'DE'
*          WINID          =
     IMPORTING
          return         = g_return
    EXCEPTIONS
         inv_query      = 1
         no_batch       = 2
         frontend_error = 3
         OTHERS         = 4.
         
IF sy-subrc <> 0.
***some error message
ENDIF.
CASE g_return.
  WHEN '0'.
**does not exist
  WHEN '1'.
*exists
ENDCASE.
