The Change and Transport System (CTS) is a tool that helps you to organize development projects in the ABAP Workbench and in Customizing, and then transport the changes between the SAP Systems and clients in your system landscape. This documentation provides you with an overview of how to manage changes with the CTS and essential information on setting up your system and client landscape and deciding on a transport strategy. Read and follow this documentation when planning your development project.

Parallel/audit testing is testing where the user reconciles the output of the new system to the output of the current system to verify the new system performs the operations correctly. Let us say, for example, the currently software is in the mainframe system which calculates the interest rate. The company wants to change this mainframe system to web-based application. While testing the new web based application, we need to verify that the web-based application calculates the same interest rate. This is parallel testing.

You can implement a condition by using either of the following ways:

     =>   By creating a rule condition - Specifies that you can implement conditions either directly in code or by using a tool, called the Rule Condition Editor. Rule conditions are stored in a separate Extensible Markup Language (XML) file. When a rule condition occurs in a workflow, the expression in a condition is evaluated and a Boolean value is returned.

     =>   By creating a code condition - Refers to defining a condition directly in code. A code condition can be created by writing a method in the code. The method contains code for the condition and returns a Boolean value.

In the template specialization, it will make the template to be specific for some data types.

One of the most common use of JSON is to fetch JSON data from a web server (as a file or as an HttpRequest), convert the JSON data to a JavaScript object, and then it uses the data in a web page.

The eval() function can compile and execute any JavaScript. This represents a potential security problem.

It is safer to use a JSON parser to convert a JSON text to a JavaScript object. A JSON parser will recognize only JSON text and will not compile scripts.

Stored procedure should return error code if some operation fails but if stored procedure itself fail than catching SQLException is only choice.

They should be initialized during the time of declaration itself otherwise it is a compilation eror
