Hi Gana,

Domain - Specifies the technical attributes of a data element - its data type, length, possible values, and appearance on the screen. Each data element has an underlying domain. A single domain can be the basis for several data elements. Domains are objects in the ABAP Dictionary.

Data Element - Describes the business function of a table field. Its technical attributes are based on a domain, and its business function is described by its field labels and documentation.

Lock Objects -Lock objects are used to synchronize access to the same data by more than one program.

Match Code -Match code object is nothing but a Search Help object.

SO you can create it from SE11 Data Dictionary.

Goto SE11 and then Select Radiobutton Search Help.

Search Help - The input help (F4 help) is a standard function of the R/3 System. The user can display the list of all possible input values for a screen field with the input help. The possible input values can be enhanced with further information. This is meaningful especially when the field requires the input of a formal key.

Hi Prudhvi,,

R U Really dont know about these Ok.i will explain in my own words

table is for storing data, wheever u r creating table u have to create fields for a field u have to mention property whether it is built in data type or existing data element,

for each data element contains domain , one domain can assign to any number of data elements

in domain u can maintain value range or value table and data type and length

in data element u can give description

search helps are nothing but match code objects for providinf F4 helps,

and lock objects are providing locks before updating the table

reward points to all helpful answers
