Process chain repair going to Debugger mode

Question

Hi everyone,
When I try to repair a failed DTP process in a process chain, it goes into debugger mode. After exiting from debug mode, I can see that DTP has been executed successfully.
Why process chain goes into Debug mode?
Secondly after successful execution of DTP process, other remaining succeeding processes are not executed.
any idea how to solve these issues.
thanks for help
Ahmad

hi guys,
Thank you all for taking time to reply.
@Muhammad: there are no breakpoint(s) in custom routines.
@Baskaran: DTP processing mode is set to Serial extraction, immediate parallel processing.
@Amit, Martin: at DTP process repair, the Debug stop at following code
* ==== Debugging ====
* Breakpoint after start routine
    if i_r_trfn_cmd is bound.
      READ TABLE i_r_trfn_cmd->n_th_bp
           TRANSPORTING NO FIELDS
           WITH TABLE KEY bpid    = 3
                          datapid = i_r_inbound->n_datapakid.
      IF sy-subrc = 0.
* --- Data ---
*     See datapackage below
* --- Debugging ---
        BREAK-POINT.                                       "#EC NOBREAK
      ENDIF.
    endif.
when I simply exit, I can see in the process chain that DTP has executed successfully, but remaining processes don't execute.
In the generated program of transformation of DTP, there are two breakpoints; one given above and the other is :
* ==== Debugging ====
* Breakpoint before end routine
    if i_r_trfn_cmd is bound.
      READ TABLE i_r_trfn_cmd->n_th_bp
           TRANSPORTING NO FIELDS
           WITH TABLE KEY bpid    = 4
                          datapid = i_r_inbound->n_datapakid.
      IF sy-subrc = 0.
* --- Data ---
*     See datapackage above..
* --- Debugging ---
        BREAK-POINT.                                       "#EC NOBREAK
      ENDIF.
    endif.
I have checked generated programs of other transformations both SAP delivered (business-content) and client custom transformations and they all have these two pieces of code.
on additional question:
when we do repair the below box appears. Can anyone explains what exactly is this? and if this has any thing to do repair going into the debug mode. What I read on
https://help.sap.com/saphelp_nw70ehp1/helpdata/en/67/13843b74f7be0fe10000000a114084/content.htm
"Specify how long (in seconds) you want the delay to be between one event being triggered and the next process starting."
I am thinking of deleting this DTP and using a new one in process chain.

Ahmad
