• Analyze the data and logic flow to identify and resolve any issues with the ou...read more

An abstract class is a class that cannot be instantiated and is used as a base class for other classes.

• An abstract class can have abstract methods that must be implemented by its subclasses.

• Abstract classes can have non-abstract methods and properties.

• An abstract class can be used to define a common interface for a group of related classes.

• Example: 'Animal' can be an abstract class with abstract methods like 'eat' and 'move', which must be implemented by its subclasses like '...read more

Multiple inheritance allows a class to inherit from multiple superclasses in OO ABAP.

• Multiple inheritance can be achieved using interfaces.

• A class can implement multiple interfaces.

• A class can inherit from one superclass and implement multiple interfaces.

• Example: Class ZCL_MYCLASS extends ZCL_SUPERCLASS implements ZIF_INTERFACE1, ZIF_INTERFACE2.

• Diamond problem can occur in multiple inheritance.

• To avoid diamond problem, use interface inheritance instead of class inheritance.

BAPI is a function module in SAP ABAP that provides a standardized interface for external applications to access SAP business objects and processes.

• BAPI stands for Business Application Programming Interface.

• It allows external systems to integrate with SAP and perform operations on SAP business objects.

• BAPIs are implemented as function modules in SAP ABAP.

• They provide a set of methods to create, read, update, and delete data in SAP systems.

• BAPIs are widely used for data exchan...read more

An interface is a contract between two systems or components that defines the methods and parameters that they will use to communicate with each other.

• Interfaces allow for loose coupling between systems or components

• They define a set of rules for communication

• Interfaces can be used in programming languages like Java and C#

• Examples of interfaces include JDBC for database connectivity and SOAP for web services

Field symbol is a pointer to a field in ABAP.

• Field symbol is used to access data dynamically.

• It can be used to avoid copying large amounts of data.

• It can be used to access data in internal tables and structures.

• Example: ASSIGN statement assigns a field symbol to a field.

• Example: LOOP AT statement uses a field symbol to access data in internal tables.

SAP is a software company that provides enterprise resource planning solutions to businesses.
