RFC 2 File Error in RFC sender: java.lang.ArrayIndexOutOfBoundsException

Question

Hello,
I'm sending data asynchronously from R3 to a file through XI, I've got the RFC destination (in R3) and sender RFC channel (in XI) configured and tested. Working fine.
Then in my report I've got the following code that sends 1 string and 4 internal tables 2 to XI:
  CALL FUNCTION 'Z_RFC_ENVIAR_DATOS_PSP'
    IN BACKGROUND TASK DESTINATION 'SAP_2_XI'
    EXPORTING
      RUTA                       = p_ruta
    TABLES
      IT_DEMANDA           = p_gt_demanda
      IT_STOCKS              = lt_stocks
      IT_CUARENTENAS   = lt_cuarent
      IT_COMPRAS           = lt_repartos.
  COMMIT WORK.
I've done that king of connection several times and allways worked but now I've got that error in the communication channel monitoring at RWB:
Error in processing caused by: java.lang.ArrayIndexOutOfBoundsException
And no message is created in XI. What can it be?
Thanks for your help

Hi Chen Lin,
The problem is with the adapter but no message is generated yet in XI, so I don't have XML yet.
The RFC sends the data to XI through the RFC destination and at this point something is wrong because that error is produced. The error is visible in both sides, In transaction SM58 at R3 I can see the error that tRFC hasn't been precessed because the ArrayIndexOutOfBoundsException.
But if I go to communication channel monitoring I can see the same error too, so that confirms that the communication between R3 and XI works fine but something is wrong and the error don't give me more details
