Date and Time          2010.06.19 11:01:46
Kurztext
     Field symbol has not yet been assigned.
发生了什么?
     Error in ABAP application program.
     The current ABAP program "FCR05205" had to be terminated because one of the
     statements could not be executed.
     This is probably due to an error in the ABAP program.
你能做什么?
     Print out the error message (using the "Print" function)
     and make a note of the actions and input that caused the
     error.
     To resolve the problem, contact your SAP system administrator.
     You can use transaction ST22 (ABAP Dump Analysis) to view and administer
      termination messages, especially those beyond their normal deletion
     date.
     is especially useful if you want to keep a particular message.
错误分析
    You attempted to access an unassigned field symbol
    (data segment 11).
    This error may occur for any of the following reasons:
    - You address a typed field symbol before it is set using ASSIGN
    - You address a field symbol that points to a line in an internal table
      that has been deleted
    - You address a field symbol that had previously been reset using
      UNASSIGN, or that pointed to a local field that no longer exists
    - You address a global function interface parameter, even
      though the relevant function module is not active,
      that is it is not in the list of active calls. You can get the list
      of active calls from the this short dump.
如何更正此错误
    You may able to find an interim solution to the problem
    in the SAP note system. If you have access to the note system your
    use the following search criteria:
    "GETWA_NOT_ASSIGNED" C
    "FCR05205" or "FCR05F00"
    "PUT_P_VGWXX"
    If you cannot solve the problem yourself and you wish to send
    an error message to SAP, include the following documents:
    1. A printout of the problem description (short dump)
       To obtain this, select in the current display "System->List->
       Save->Local File (unconverted)".
    2. A suitable printout of the system log
       To obtain this, call the system log through transaction SM21.
       Limit the time interval to 10 minutes before and 5 minutes
       after the short dump. In the display, then select the function
       "System->List->Save->Local File (unconverted)".
    3. If the programs are your own programs or modified SAP programs,
       supply the source code.
       To do this, select the Editor function "Further Utilities->
       Upload/Download->Download".
  4. Details regarding the conditions under which the error occurred
     or which actions and input led to the error.
