Process Chain Status is Red even though all processes are successful.

Question

I implement ABAP Code by using standard function module "RSPC_CHAIN_START" for execute process chain and return status of process chain after execute completely as following code:
Execute Process Chain
CALL FUNCTION 'RSPC_CHAIN_START'
  EXPORTING
    I_CHAIN             = I_CHAIN
    I_SYNCHRONOUS       = I_SYNCHRONOUS
IMPORTING
   E_LOGID             = P_LOGID.
  If sy-subrc = 0.
    gt_status = 's'.
    WHILE gt_status = 's'.
Get Status of Process Chain
      CALL FUNCTION 'RSPC_API_CHAIN_GET_STATUS'
      EXPORTING
      i_chain              = I_CHAIN
      i_logid              = P_LOGID
     IMPORTING
      E_STATUS             = gt_status
      E_MESSAGE            = P_MESSAGE.
Status G or F - Report that the Chain is Successfully Completed.
Status A - The chain is Currently running
Status R or X - Report that the chain has ended with Errors.
    CASE gt_status.
    WHEN 'A'.
Process chain is running
      gt_status = 's'.
      P_MESSAGE = ''.
    WHEN OTHERS.
Process chain is completed
      exit.
    ENDCASE.
    IF gt_status = 's'.
       WAIT UP TO 2 SECONDS.
    ENDIF.
ENDWHILE.
Display Message
  IF gt_status = 'G' or gt_status = 'F'.
    MESSAGE i162(00) WITH P_MESSAGE.
  Else.
    MESSAGE e162(00) WITH P_MESSAGE.
  ENDIF.
  ENDIF.
From above code, when execute this function module, sometimes status of process chain is shown as canceled 'X', therefore, output of this function module is shown as "The process chain is canceled". When monitor process chain in RSPC log view, the process chain status is also shown as canceled 'X' and status of all process in process is green, however, after wait for a while, the status changed from canceled 'X' to successful 'G'.
Why did the status of process chain show as canceled 'X' even though finally process chain status is successful ? If I want to check status of process chain after execute completely, which status should to check in ABAP code?

Using that FM.. u will be providing the Instance and Variant of the failed process.. and hence the reload will start from the failed process but not the entire chain...
In general the process status shud finish then or based on the link combination  the change from one process to other will happen...
try to maintain a wait time between the process atleast 2 to 4 secs..
thanks
hope this helps..
