Scheduling a background job through programming (Using Function Modules )

 

  • Till now, we were scheduling our background job through SM36 transaction code.
  • Now, We want to schedule our background job through coding.
  • SAP has given use various function modules which we can use for scheduling a background job through programming.

Various function modules which can be used for scheduling a job :-

1. JOB_OPEN :-

  • This function module is used to create a background job.

2. JOB_SUBMIT / SUBMIT :-

  • The function module JOB_SUBMIT or ABAP statement SUBMIT adds a step to the background job.

3. JOB_CLOSE :-

  • This function module process the background job.

Implementation :-

  • Step 1 :- Create a executable program in ABAP Editor ( SE38) .

  • Step 2 :- Call the function module JOB_OPEN to create a background job.

    • In this function module we will pass the job name and job class for our job and it will return the job count for our job which we will use later in add step purpose.


  • Step 3 :- the next step for the job scheduling was to add program name and variant, so we will use JOB_SUBMIT function module for the same purpose.



  • Now, If I execute this program my job will went to schedule status.

  • So, we need to give start condition and for that purpose, we will use JOB_CLOSE function module.

Understanding Different Types of SAP Function Modules: Normal, RFC, and Update

Image
  1. Normal/Regular Function Module :- It can be called inside the system. Here Pass by value + Pass by reference both is fine. 2. RFC Function Modules :- You can call from same system or from another possible. In RFC function module you can only have pass by value. In the same system if you are going to add the DESTINATION NONE’ while calling the RFC then it’ll be called in separate session. 3. UPDATE Function Modules :- This is generally used to update the database record. Update Function Module can be called from the same system. ( Background RFC / trfc / grfc ) This is used to achieve generally the SAP LUW. Some time we use from performance perspective also. When COMMIT WORK gets executed then Update starts getting executed. Important Questions on Update Function Modules :- When Update function Module gets Triggered ? ON COMMIT WORK IF a update function module gets failed, under which transaction we can see that ? OR What is the T-Code for moni

Unlocking SAP ABAP Secrets: Interactive Classical Reports with GET CURSOR, At User Command, and a Comparison of HIDE Statements

Image
 Welcome back everyone, We were discussing about the interactive classical reports, so let’s continue it. Interactive Classical Reports- GET CURSOR :- In Interactive Classical Reports, GET CURSOR statement is used to create secondary list according to cursor position. The parameter FIELD provides the name of an output field. The parameter VALUE provide the output value. Syntax : GET CURSOR FIELD <lv_field> VALUE <lv_value>. In the above syntax - the field name and field value will be returned in to variables lv_field and lv_value respectively. Requirement :- If you remember, In our last two blog, We have been displaying the order header table in a basic list and order item table in the secondary list. We have used SY-LISEL and HIDE statements to achieve the requirement. Now, we have to use the get CURSOR to achieve the same to same requirement.

Mastering ABAP: A Step-by-Step Guide to Function Modules and Groups for Modularized Programming

Image
  Function Modules :- It is a modularization technique. The transaction code to create a function module is SE37. To create a function module, we need to create a function group. Function Group :- Function group is a container for the function modules. The transaction code to create a function group is SE80. A function group can store up to 99 function modules. Requirement :- let’s create a function module for sum of two numbers. 1. Creation of function group :- Step 1 :- Go to SE80 transaction code → Object Navigator. Step 2 :- From the drop down select function group. Step 3 :- Give a name of function group. Step 4 :- press enter. Step 5 :- Click on yes a popup screen will appear. Step 6 :- Give short description → press enter → Assign package and transaction request and press enter. Step 7 :- Right click on function group and click on activate to activate the function group. Step 8 :- You will see two includes, will be added after ac
