Hello,

Data element (semantic domain)

Data element

A data element is an elementary type. It describes the type attributes

(data type, field length and possibly the number of decimal places) and

screen information (explanatory text or field help) about unstructured

data objects (table fields and structure fields or variables).

Table fields and structure fields with the same contents should refer to

the same data element. This ensures that the attributes of these fields

are always consistent.

A data element can be referenced in ABAP programs with TYPE. This

permits you to define variables that take on the type attributes of the

data element in an ABAP program.

If useful reward.

Data types are of two types.

1.Calculation fields

2.Non-calculation fields

Calculation fields have the data types P,F,I

P-Packed

F-Float

I-Integer

Non-calculation fields are such as name e.t.c

These have the data types such as C,N,D,T e.t.c

C-Character

N-Number

D-Date

T-Time

Data Type is different from data element

Data element consists of teh information of the data type,length e.t.c

There are two types of data types.One is predefined data types and another one is user defined data type. Predefined data types are already inbuuit in sap. User defined data types are defined by the user. It depends on the reqirement.

Data type describes how a field can be display to an end user. It consist of Domain.Domain describes technical characteristics of the field (type, length)

Data type in reference to what???

In data dictionary, it can be a table type, or a structure or a data element.

and in an ABAP program, it will be an element which holds technical details for a data declaration.

Hope I am clear...
