Solved: Scheduling jobs dynamically

Former Member · ‎2005 Oct 10

Hello All,

I would like to know if there is a way to schedule jobs dynamically. For example: If the user wants to set up a series of jobs 2days in advance can we do it by creating a selection screen on which user has the ability to enter the date and time when he wants to schedule the jobs and I can trigger an event which is already scheduled with the series of steps to be executed on that date and time instead of going to tcode "SM36".

You help will be appreciated.

Thanks

Pavan,

You can schedule jobs dynamically. Look at the function modules JOB_OPEN, JOB_SUBMIT, JOB_CLOSE.

Hi Pavan;

You can schedule the background jobs to run peridodically after an event, then trigger the event in ABAP using BP_EVENT_RAISE. The events are maintained in transaction SM62.

Hello Ravi,

Can you give me an example.

Say I have a series of jobs A,B,C,D and the user inputs a date and time when the these jobs need to run. Based on the user input the jobs should run as

1. A

2. B

3. C

4. D

Check out this sample program...



report zrich_0002.

        l_valid,
        ls_params like pri_params,
        l_jobcount like tbtcjob-jobcount.

parameters: p_job type tbtcjob-jobname.
parameters: p_prog(30) type c.
parameters: p_sdat like sy-datum.
parameters: p_stim type sy-uzeit.

start-of-selection.

* Get Print Parameters
  call function 'GET_PRINT_PARAMETERS'
       exporting
            no_dialog      = 'X'
       importing
            valid          = l_valid
            out_parameters = ls_params.

* Open Job
  call function 'JOB_OPEN'
       exporting
            jobname  =  p_job
       importing
            jobcount = l_jobcount.

* Submit report to job
  submit (p_prog)
       via job     p_job
           number  l_jobcount
       to sap-spool without spool dynpro
           spool parameters ls_params
              and return.

* Schedule and close job.
  call function 'JOB_CLOSE'
       exporting
            jobcount  = l_jobcount
            jobname   = p_job
            sdlstrtdt = p_sdat
            sdlstrttm = p_stim

            .

Rich,

Thanks for the input but when I created a test program and defiened a job called "ZTEST" with 2 steps and when I execute the program it gives an error -

Exception condition "JOB_NOSTEPS" raised.

Any thoughts?

Pavan

Former Member · ‎2005 Oct 10

Please post the code where you added the steps to the job. This error indicates, that no steps were inserted into the job due to an error condition. Either you didn't give the selection screen values/variant for the program in the steps or the job is not created.

Srinivas,

I used the same code which Rich posted above.

I did create the job with 2 steps in it (2 reports).

Not sure whats going on..... This sample submits one job with 2 steps, and it works great. Of cousr

Rich,

Thank you very much for the input. I have one more question:

Can I use a variant of p_prog1 during submit of p_prog1?

Pavan

Former Member · ‎2005 Oct 10

You need to use the option 'USING SELECTION-SET variant' in your SUBMIT statement.

Srinivas

RichHeilman · ‎2005 Oct 10

Yes, as Srinivas said, if you are doing the submits dynamically like this, you must use a predefined variant.

Rich/Srinivas,

Thank you very much for your responses. I have a one more question:

Let us say as of today I have 3 steps (A,B,C) to be executed in a particular job and next year another step needs to be added (due to business process changes) inbetween B and C (A,B,D,C) is there a way we can do this without changing the existing program.

Something like

Define a job with the various steps. Once the user selects the start date and time then the job is executed with the steps created and if there is a new step which needs to be added then just insert a step in the current job.

Please let me know...

Pavan

RichHeilman · ‎2005 Oct 10

Yes, if you were to just running programs, you could use a select-option instead of a parameter on the selection screen. Then all you need to do is update a variant of the driver program to include the new step. Since you are using variants as well, you need to tie the variant to the program being submitted. So in this case, I would suggest maintaining a custom table with ..

Job Name

Step Number

Program Name

Variant

Then you can retrieve these records at run time and loop thru them and build the job. Then all you need to do is add the new step to the custom table. No programming changes.

Please remember to award points for all helpful answers. If you problem is solved, please mark as solved. Thanks.

Here is a example which uses a custom table.



report zrich_0002.


data:
        l_valid,
        ls_params like pri_params,
        l_jobcount like tbtcjob-jobcount.

data: icusttable type table of zcusttable with header line.

parameters: p_job type tbtcjob-jobname.
parameters: p_sdat like sy-datum.
parameters: p_stim type sy-uzeit.


start-of-selection.

* Get Print Parameters
  call function 'GET_PRINT_PARAMETERS'
       exporting
            no_dialog      = 'X'
       importing
            valid          = l_valid
            out_parameters = ls_params.


  select * into corresponding fields of table icusttable
            from zcusttable
                       where jobname = p_job.
    sort icusttable ascending by jobname stepnumber

* Open Job
    call function 'JOB_OPEN'
         exporting
              jobname  = p_job
         importing
              jobcount = l_jobcount.


* build steps
    loop at icusttable.

      submit  (icusttable-program)
           via job     p_job
               number  l_jobcount
           using selection-set icusttable-variant
           to sap-spool without spool dynpro
               spool parameters ls_params
                  and return.

    endloop.

* Schedule and close job.
    call function 'JOB_CLOSE'
         exporting
              jobcount  = l_jobcount
              jobname   = p_job
              sdlstrtdt = p_sdat
              sdlstrttm = p_stim
*            strtimmed = 'X'
              .

Hi All,

My requirement is to trigger a particular job after a certain event.

For example if an entry is created in table TRFCQIN,

I want a certain job to run after an entry is created in the table TRFCQIN,

TO check the entry in table TRFCQIN everytime ,I do not want to create and shedule another background job.

Is there any other Possible way to do it.

Any help would be highly appreciated.

Regards
