    An exception has occurred which is explained in more detail below. The                        
    exception is assigned to class 'CX_SY_DYNAMIC_OSQL_SYNTAX' and was not caught                 
     in procedure                                                                                 
    "HRPAD_PERSK_F4_EXIT" "(FUNCTION)", nor was it propagated by a RAISING clause.                
    Since the caller of the procedure could not have anticipated this                             
    exception, the current program was terminated.                                                
    The reason for the exception is:                                                              
    The current ABAP program attempted to execute an Open SQL statement                           
    containing a dynamic entry. The parser returned the following error: "The                     
     character "&A" is not valid here. A blank may be missing or there may be too                 
     many blanks."
