Hi,

1.What is the difference b/w Data Class and Delivery Class?

2.What is the necessary of Data Element, because without dataelement also we can create one field?

3.What is the difference b/w Data Element and Domain?

4.What is the work process?

Hi,

1.The Data class determines in which tablespace the table is stored when it is created in the database. What is a Size Category? The Size category describes the probable space requirement of the table in the database. How Many types of size categories and data classes are there? There are five size categories (0-4) and 11 data classes, only three of which are appropriate for application tables:

The delivery class controls the degree to which the SAP or the customer is responsible for table maintenance

- whether SAP provides the table with or without contents.

- determines the table type. - determines how the table behaves when it is first installed, at upgrade, when it is transported, and when a client copy is performed

4 .A work process is where individual dialog steps are actually processed and the work is done. Each work process handles one type of request.

Regards,

Rushi.

Hi

1.Delivery class

The delivery class controls the transport of table data when installing or upgrading, in a client copy and when transporting between customer systems. The delivery class is also used in the extended table maintenance.

There are the following delivery classes:

A: Application table (master and transaction data).

C: Customer table, data is maintained by the customer only.

L: Table for storing temporary data.

G: Customer table, SAP may insert new data records, but may not overwrite or delete existing data records. The customer namespace must be defined in table TRESC. (Use Report RDDKOR54 here).

E: System table with its own namespaces for customer entries. The customer namespace must be defined in table TRESC. (Use Report RDDKOR54 here.)

S: System table, data changes have the same status as program changes.

W: System table (e.g. table of the development environment) whose data is transported with its own transport objects (e.g. R3TR PROG, R3TR TABL, etc.).

The Data class determines in which table space the table is stored when it is created in the database.

2. yes u can create without refernce to data element

3. · A domain describes the technical settings of a table field.

· A domain defines a value range, which sets the permissible data values for the fields, which refers to this domain.

· A single domain can be used as basis for any number of fields that are identical in structure.

A data element describes the role played by a domain in a technical context. A data element contains semantic information.
