Inbound idoc processing using custom FM to cancel sales orders

Question

hello all,
         I have a scenario where i need to create a customized function module which is assigned to custom message type. and this function module is triggered when inbound idoc comes, which will process idoc data for cancellation of sales orders. If an errror occurs than the error during cancellation has to be reflected back in the idoc status.
      can anyone tell me how exactly i can log the status and reflect it back, how exactly can i do this
     And what are all the objects i need to create to succusfully execute  this scenario, i have created message type, function module, i am using orders05 do i need to create process code also.
Thanks,

Hi Krishna,
   Hope you are done with the Inbound function module creation. But, just creation of function module would not be enough, what u said that is like creation of Process code should also be done.
WE42 is the transaction code for inbound process code.
And while creation of the process code, we need to do few things like:
We need to create an entry of the inbound function module in BD51 transaction or so. And coming to updating of the status, open any of the inbound function module, you will observe that there is a standard subroutine which will update the IDOC_STATUS record. You can implement the same logic whenever you want to update an error message.
