TCPEV_CPT_REQ_DISCARD error

  • hi,

    I am developing IN application using the sample INTU.

    From SSP, i am sending the dialog open, initialDP and then delimit.

    when I receive the dialog at SCP, i am sending the applycharging, RRBCSM and continue and delimit messages from INTU_process_invoke function. 

    I am receiving the applycharging  request at SSP, but after that at SCP i am getting TCPEV_CPT_REQ_DISCARD

    error, so i am not able to receive the next messages at SSP.

    here is the log at SCP (INTU).

    Can any one tell me where i went wrong.  i am sending three messages (apply charging, RRBCSM, continue) followed by delimit. should i have to send delimit after every message.

    any help in this regard is appreciated.

    thanks a lot.

    somu.

     

  • You might want to check the invoke ids of the operations you're sending back. They need to be unique within the dialog in that direction.

  • where we have to change this configurations ... can u please help me
