Structure:
Collection of multiple fields. It’s application level artifacts gets created.
1. INCLUDE STRUCTURE:
When we include a structure in a table all the fields define in the structure become part of the
table .So If we need same set of fields in multiple table ,we can create one structure and we
can include it in multiple table instead of specifying the same fields multiple time in each table.
2. APPEND STRUCTURE:
 If there are requirements to add custom field to the standard table, we can create
append structure and add the fields to the structure. Upon activating the structure,
will add the custom fields to the table
 Append structure cannot be included in multiple table, it can be appended to a single.
3. CUSTOMER INCLUDE:
Customer include are include structure whose name starts with CI. If SAP give CI then only we
can add in table. We can go to change mode and add fields to the customer include. Access
key is not required.
Sometime SAP creates the customer include and include in multiple tables.So if we add the
field to the customer include, the fields are added to multiple table which use that customer
include. This way multiple append is not required.
VIEW:
It does not store the data. Only pulls the data from table and display it.
TYPES OF VIEW:
