Process Chains with Event Trigger

Question

Hi Experts,
Happy Valentine day.
I have a requirement to run a Process Chain using Event IDs. Now these Evenrt ID should be triggered by a Program which raises this Eovent. Then this Program should be scheduled in BAckground to run periodically. Has anyone done this before. If yes, could you please shower some light on this topic with details on the steps.
Thanks

Hi,
1)You can make the process chain to be trigered by an event.
You create user events in SM62. In SM62, next to "User even names", click on Maintain and press Enter. Click on the Create icon to create a new event (let's call it ZEVENT).
Next, in your process chain, change the Start variant to be scheduled "After event", and put in ZEVENT for the event name. Also, click on the "Periodic job" at the bottom. This will automatically reschedule the jobs for the process chain after it executes.
Next, create an ABAP program (let's call it Z_EVENT_RAISE) to call the function module BP_EVENT_RAISE. You're code can look like this:
codeREPORT Z_EVENT_RAISE.
PARAMETERS: P_EVENT LIKE TBTCO-EVENTID.
CALL FUNCTION 'BP_EVENT_RAISE'
EXPORTING
EVENTID = P_EVENT.
IF sy-subrc 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.[/code]
This ABAP program will prompt for an event name, so you will need to create a variant (let's call it ZEVENT) which will save the value of the event name (also ZEVENT). You will need the variant name to be able to trigger the event in a batch job.
Now all you need is the batch job. Use tcode SM36 to create a batch job where you call the ABAP program (Z_EVENT_RAISE) using the variant (ZEVENT).
Note, SM64 only triggers an event manually.
and you can copy this job to schedule it three times a day.
2)In the Start process of your process chain, select Direct Scheduling and then click the Change Selections icon. This will bring you to the Start Time window where you can put in the Date/Time you want to start your process chain. At the bottom of this window, click on the Periodic job box and you will notice another icon way at the bottom called Period Values. Click this to determine what frequency the job should be rescheduled (ie. daily, weekly, etc.).
3)you can do this by right-clicking on the start process, selection "Maintain Variant", choose "Direct Scheduling". Next select "Change Selections", pick your date and time, set your period values and you're done.
