Except.                    CX_SY_FILE_OPEN_MODE
ABAP Program               RSUMOD02
Application Component      BC-UPG

Short text
     File "/usr/sap/put/log/umodstat.dat" is not open.

 What happened?
     Error in the ABAP Application Program

     The current ABAP program "RSUMOD02" had to be terminated because it has
     come across a statement that unfortunately cannot be executed.

Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_FILE_OPEN_MODE', was not
     caught in
    procedure "GET_PHASE" "(FORM)", nor was it propagated by a RAISING clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    When accessing the file "/usr/sap/put/log/umodstat.dat", the system recognized
     that this file is
    not open. Therefore, the file cannot be accessed.
