Introduction:

In this Blog, we will see how to execute a Program via a Batch Job and optimize the Batch Job execution time by splitting the number of records into different sets and executed each set via Multiple Batch Jobs.

The Number of records in each set and the Maximum number of jobs for this program that can be in Released / Active / Scheduled status can be entered via a Maintenance Table in TCode SM30.

I have considered a scenario to update Marketing Attributes in multiple Business Partners and provided pseudo code to update the Marketing Attributes in the Business Partners and pseudo code to schedule the program to update Marketing attributes as a Batch job and split the records to be processed in each Batch job and schedule several batch jobs accordingly. Using these pseudo codes developers can build their logic accordingly.

Steps:

  1. Define a Parameter Table with Two fields Parameter Name and Value and create a Maintenance View for this table and make entries in the Maintenance View for Number of records to be processed in each set of Batch Job and maximum number of batch jobs that can be in Released / Active / Scheduled status.

  2. In this example, I have provided pseudo code to update the Marketing Attributes in a Business Partner.

  3. The updation of Marketing attributes in the Business Partner will be done via Batch Jobs that would be scheduled via another report program. The number of Batch Jobs that would be scheduled is based on number of records to be updated and the entry in the Parameter table that holds both the Number of records to be processed in each set of Batch Job & Maximum number of batch jobs of this program that can be in Released / Active / Scheduled status.

  4. I have provided pseudo code for two programs that would help developers to build functionality accordingly:



         Batch Job Name: ZBP_ATTR_UPD_1, ZBP_ATTR_UPD_2 , ZBP_ATTR_UPD_3 etc.

Detailed Explanation of the Steps:

  1. Define a Parameter Table with Two fields Parameter Name and Value and create a Maintenance View for this table.



       Make entries in the Maintenance View for Number of records to be processed in each set of               Batch Job and maximum number of batch jobs that can be in Released / Active / Scheduled               status.

TCode: sm30


          Please Note:

  • Parameter JOB_SIZE indicates the number of records to be processed in each set of Batch Job.

  • Parameter MAX_JOB_COUNT indicates maximum number of batch jobs (for the Program ZBP_ATTR_UPD) that can be in Released / Active / Scheduled status.


 

2. Pseudo code to update the Marketing Attributes in a Business Partner

    Program: ZBP_ATTR_UPD.

    Logic:

  • Import the list of BPs to be updated and assign the various values to a work area and    insert into an internal table. The List of BPs to be updated is exported from another program ZSCH_JOB.

  • Use Function Module ‘CRM_MKTBP_SAVE_BP_LIST’ to update the Attributes into the  Business Partner.

3. Pseudo code Report Program to split the records to be updated into multiple sets depending on          Maximum number of records permitted in a Job and schedule Jobs for each set accordingly.

    Program: ZSCH_JOB

    Logic:

  • First select data from the database table that holds the Parameter values for Maximum             number of Records in a Job and maximum number of Jobs that can run at a time.

  • Then select data( that is Business Partners whose Marketing attributes needs to be updated ) from the database table and validate whether the number of records is more than (or) equal to the job size and accordingly pass the to a subroutine to schedule a Job to update the records. Also, delete the records that are being passed to the job(scheduled in the subroutine) from another internal table and use this set to schedule Job for final set of records.

  • In the subroutine validate for any Jobs of the Program ZBP_ATTR_UPD and if the                    number of jobs in Released / Active / Scheduled status are more than the Permitted                  Job Count then wait for 10 seconds and validate again. If the number of jobs in                          Released / Active / Scheduled status are less than the permitted Job Count then                      schedule New Jobs accordingly.

Scenario 1:

List of Business Partners whose Marketing Attributes needs to be updated:


Before Execution, no Attributes present in the Marketing Attributes Tab of the Business Partners:








Parameter Table screenshot:



sm37 screenshot:


Now execute the Program ZSCH_JOB via the TCode for this Program ZSCH_JOB_TCODE.


Output:


Now check in SM37 for the Batch jobs:



Spool of Job ZBP_ATTR_UPD_1:


Spool of Job ZBP_ATTR_UPD_2:


Spool of Job ZBP_ATTR_UPD_3:


Business Partners have been updated as per below screenshot:








Now delete the Assigned attributes from the Business Partners for test data for Scenario 2.

Sample BP screenshot with assigned Attributes Set, Attributes deleted:


In a similar way delete all assigned Attributes Set, Attributes to all the Business Partners.


Parameter Table screenshot:



SM37 Screenshot before execution:


Now, execute the TCode ZSCH_JOB_TCODE to schedule the Jobs to Update the Business Partners.


Output:


SM37 Screenshot:


Spool of Job ZBP_ATTR_UPD_1:



Spool of Job ZBP_ATTR_UPD_2:


Screenshot of BPs after Execution. All the Business Partners have been updated with the Marketing Attributes:









Conclusion:

By Maintaining the values in the Parameter table the number of records to be processed in each Batch Job and Maximum number of Batch Jobs for this Program in specific status can be controlled. By using the above pseudo codes provided for the programs developers can build their logic accordingly to schedule Batch Jobs from report Programs and optimize Batch Job performance.
