Introduction to OData | Ui5 | Fiori

 

  • SAP UI5 is a framework to develop responsive web applications.

    1. Framework :- A Framework is a collection of libraries.
    2. Library :- A Library is a collection of classes
    3. Class :- A Class is a collection of attributes, functions, aggregations and events.
    4. Responsive :- A web application which is used to work in all the devices with same code. It has ability to adapt itself according to the devices.

    SAP ABAP Applications :-



  • In case of SAP ABAP Apps, almost all the functionalities are executed under server.

  • So, ABAP Apps are technically known as Stateful applications.

  • In stateful applications server will be busy and over loaded, so performance is degraded.

SAP Ui5 / Fiori Apps :-



  • In Case of SAP Ui5 / Fiori Apps, almost 95% of functionalities will be executed under client side.
  • So, SAP UI5 / FIORI apps are technically known as stateless apps.
  • In stateless apps the server will be free and not over loaded so we can expect best performance.

SAP ABAP Apps Vs SAP Ui5 / FIORI :-



ODATA :-

  • ODATA acts as a backend for Ui5 / FIORI.
  • The main transaction codes that will be used are SE11 , SE24, SE80, SE37.
  • SEGW :- SAP OData service development.

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. Code :- ************************************************************* *Start of Program *Declaring Strcutrure

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
