Table Maintenance Generator (TMG) :

is a tool which is used to customize tables created by end users can be changed as

required, such as making an entry to that table, deleting an entry, modifying an existing

entry etc.

Table Maintenance generator can be created using transaction SE54 or SE11.

We can check the table maintenance dialog in SM30 or SE16.

Reasons to use Table Maintenance Generator

In the production system, end-users will not be having access to

transaction codes like SE11 and SE16.

With the help of table maintenance generator, we can edit or create

multiple entries.

Various events can be added to the table maintenance generator to

maintain the entries.

TMG can also be created on Views.

Views : By defining a view, you can define an application-dependent view

that combines this data distributed on several tables.

The data of a view is derived from one or more tables, but not storedphysically.

Types of Views

o Projection views : are used to hide fields of a table

o Help views : can be used as selection method in search helps.

o Maintenance views : permit you to maintain the data distributed on

several tables for one application object at one time.
