SAP Database Table Creation & Activation

As we all know every database tables are collection of fields, in which fields are made up of columns and rows. In SAP database we have more than 8000 defined tables. Tables can be defined independent of the database in ABAP Dictionary. When a table is activated in ABAP Dictionary, similar copy of it’s fields are created in the database as well.

To define tables in ABAP dictionary, you need to define fields first, so to determine a field, you need to specify data type, length and description.

DOMAIN = Data type + Length (Domain identifies the technical attributes)

Data Element = Description (Data Element identifies the semantic attributes)

FIELD = Data Element + Domain
