How do I set up a periodic job to run only if the previous period job ran

Question

I want to sent up a process that will run on the second work day of the month that will run program A.  If program A runs successfully, then I want to run program B.  If B is successful, then program C.
I tried to setup A to run on the second work day of the month using a calendar. 
I then setup B to run after event A.
I then setup C to run after event B.
This all worked great the first month.  Now we are coming up on the second month, and A is still scheduled and will run on the second work day of this month, but B and C are no where to be found.
I found various threads to use bp_event_raise and SM62, but I guess since I am not an ABAP programmer I did the program wrong.
can someone please give me detailed instructions on how to set this up.

Hi John,
Create a process Chain with start variant sheduled using EVENT.
1. Create a event in TCODE SM62. In the Event tab on the process chain give the event ID and a Parameter name.
2. In SE38, create a program. call method RAISE of class CL_BATCH_EVENT. Give Event ID and Paramter name as given in Process chain variant.
Coding will be like:
if sy-datum+6(2) = '02'.
  CALL METHOD cl_batch_event=>raise
    EXPORTING
      i_eventid                      =
      i_eventparm                    =
     i_server                       =
     i_ignore_incorrect_server      = 'X'
   EXCEPTIONS
     excpt_raise_failed             = 1
     excpt_server_accepts_no_events = 2
     excpt_raise_forbidden          = 3
     excpt_unknown_event            = 4
     excpt_no_authority             = 5
     others                         = 6
  IF sy-subrc <> 0.
  MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
             WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
  endif.
Schedule this program in background daily. when eve the date in '02' the event will be triggered.
3. Place the process type "ABAP progam", maintain the variant as Program A.
4.  Place the process type "ABAP progam", maintain the variant as Program B.
5. Place the process type "ABAP progam", maintain the variant as Program C.
Connect all this with tpye only on Success.
This will ensure that program A will be executed on 2nd of every month. If success Program B and then Program C.
