Dump while executing QGA4

Hi All,

     We have upgraded from 4.6C to ECC, and now getting dump while executing the TCODE QGA4,

     Error stated below :

    *The exception, which is assigned to class 'CX_BADI_MULTIPLY_IMPLEMENTED', was  not caught and therefore caused a runtime error. The reason for the exception is: No more than one implementation can be selected for the current BAdI *

   Kindly help

Thanks in advance
