How to Add a Custom Field to QA11

I am a SAP ABAP consultant and recently I have been requested to make enhancements to QA11 screen. After some research, I could manage to put things together. And I thought, it is worth creating a complete tutorial on that topic.

Therefore, in this article, I would to share with you how to add the material group field to the QA11 screen and QALS table.

We need to complete following steps;

◉ Add our custom Z field to structure

◉ We create a Function Group.

    ◉ We are creating a screen.

    ◉ We write the input and output codes.

    ◉ We create functions.

◉ We are creating BAdI implementation.

    ◉ We enter the filter value and screen information.

    ◉ We write the GET_DATA and PUT_DATA methods.

Creating Change Documents for a Specific Field of a Database Table

In this blog i will try to demonstrate how you can track any change in a particular field of a database table. As you may already know, in some cases it is very crucial to see the change history of fields. So that we can analyze any problem easier and also, we can see what happened before the case that we are trying to analyze and find out the root cause.

Let’s start with creating a very simple database table and determine one of the fields inside it as trackable. By this way the changes (including creation and deletion) will be recorded in a particular table. (We will see which table it is 😊)

I won’t bother you with creating a table step by step and I will just display the database table I have created. ( Below picture ↓ )

Gobang Game write in ABAP OO!

This is a small game, Gobang, you can play with an AI(not very smart).

Just write it for learning abap oo and new Syntax.

If any question, please leave a message.

looks like a ALV? haa, yes, this is a ALV.

Applying MVC in Abap

In this blog post, I would like to share a few thoughts on how to write better code in SAP Abap by applying MVC to code structure.

I work as an Expert Abap consultant and sometimes fellow developers are asking advices on writing better code. There are many patterns, rules in coding world to help you to write better code. MVC is one of them, and I will try to explain where MVC fits in Abap development.

Previous to Abap, I worked with many different programming languages and my favorite languages are the object oriented ones, such as Java, C# and of course Abap. I like object oriented languages, because, you can create a model of the required algorithm in small modules, you can re-use code and encapsulate complexities. I believe, it is important to write lego like, modular, reusable code. That makes coding more fun and less painfull.

Cancel BTP workflow instance from ABAP

Introduction:

As an abapper most of us might be new to calling external APIs from the ABAP environment. There are lots of APIs on cloud foundry or deployed elsewhere which we can use as per as our need. Most of them use the OAuth 2.0 authentication and other authentication processes.

You must have heard about SAP Workflow Management Triggering the workflow and getting in my In Box. But What about cancelling the running workflow instance from the ABAP environment.

In this blog we not only learn how to cancel the workflow instance but also we can use this to call any APIs which uses OAuth 2.0 authentication.

Material Characteristics Batch View Report

I’m starting the SAP blog page with a report. In this report, we will try to show the characteristic values entered under the material class in the material master data to the user in the form of a report.

I am working as an ABAP developer in a company that uses SAP. The reason why we need this report is that our production planning department wants to see the characteristics they defined for the materials collectively. Material characteristics can be obtained with the CLAF_CLASSIFICATION_OF_OBJECTS function. Since we will query the materials collectively, we will read directly from the tables to gain performance.

Reusing Class Methods Should Be Easier

One of the short comings of ABAP is the ability to find and reuse class methods. It is easy to find functions from within the ABAP editor by clicking the [Pattern] button. But to find a method you first need to know what class it is in.

One way to overcome this is to search the table VSEOCOMPDF from SE16 but that’s a bit awkward, so I have written the below program to search for and display a list of methods based on selection criteria. I have written the code as a report with local classes to make it easily portable.

To implement this you can simply copy and paste the code into a new report in SE38. Here it is called ZFIND_METHOD but you can choose any name that suits you. When you save the code you can make it a local object. There is no need for this program to be transported.

Using RFC adapter in the SAP integration suite

Overview:

This blog post intends to show how to use an RFC adapter in an integration flow (iflow as we would be referring to in this blog) for fetching data from the SAP ERP system.

We have various adapters provided by SAP which can be leveraged based on a particular requirement. In this blog, I am focusing on the RFC adapter and will provide you with a brief understanding of how you can use it.

Targeted Audience: 

Beginner level in integration suite. Basic ABAP knowledge would be a plus.

Even if you don’t have either, I believe this can give you a fair idea of where to start!!
