Object


An object is a special kind of variable that has distinct characteristics and behaviors. The characteristics or attributes of an object are used to describe the state of an object, and behaviors or methods represent the actions performed by an object. An object is a pattern or instance of a class.

Types of Object


Each repository object belongs to a certain object type. ... Object type groups are hierarchically organized groups of repository object types, which can be processed by the Classification Toolset.

A class is used to specify the form of an object and it combines data representation and methods for manipulating that data into one neat package. The data and functions within a class are called members of the class.

A data object is an instance of a data type and occupies as much memory space as its type specifies. An ABAP program only works with data that is available as content of data objects. Data objects are either created implicitly as named data objects, or explicitly as anonymous data objects using CREATE DATA


Objects are of two types


1) Customize: Z/Y Created by technical Consultant

2) Standard: Except Z/Y Provided by SAP

Transport Request


Transport Requests (TRs) – is a kind of 'Container / Collection' of changes that are made in the development system. It also records the information regarding the type of change, the purpose of transport, request category and the target system. It is also known as Change Requests.


Types of transport change request:


Workbench Request: Workbench requests are cross-client. ...


1) Customizing Request: Customizing requests are client specific

2) ALOG – It Specifies the Application Log.

3) SLOG – It specifies the Job steps.

4) ULOG – Tp commands.


Difference between Work Bench Request and Customizing Request


Workbench request: it can be programs (repository objects) and cross client data (ie not specific to one client).


Customizing requests: Changes to client-specific Customizing objects are recorded in customizing requests. Customer customized data designed for a specific client is transported to another client using customizing request.


T-codes for TR: SE01/ SE09/ SE10
