What is domain and dataelement.....diff b/w domain and data element

Question

dear all
what is domain?
what is data element?
In one domain how many data elements are possible to used?
with out data element how can u create a table? explain briefly.

Answer 1

To clarify it little further the Data element and Domains are used in combination where similiar type of data fields are to be used with some more additional characteristics to each Data element.
For example consider creating a table which contains Employee details. The Columns Name1 and Name2 are to be of type char and length 40. There are 2 ways to do this,
1. You can assign the fields Name1 and Name2 directly to CHAR40(as the data element) in SE11. But this will make both the fields to have same characteristics with no difference among them.
2. The other way is to assign the columns Name1 and Name2 to seperate Data elements say DE_NAME1 and DE_NAME2. This method has tha advantage of adding further charectristics and labels to the data element. Hence in this case you can add a label "Name1" for the data element DE_NAME1 and "Name2" for data element DE_NAME2. And both these data element will point to the same domain CHAR40, hence length and type is same.
Hope this helps.
