Day 4 — Table Maintenance Generator (TMG) and SM30

What is Table Maintenance Generator (TMG)? Why do we use SM30?

TMG (Table Maintenance Generator) is used to create a maintenance screen for a custom table. SM30 is used to add, update, and delete table records. Why Do We Use TMG? Suppose we create a custom table called ZBRANCH_MASTER. The business user wants to add new branch details. SE11 can create the table but cannot be used by business users to maintain data. SE16N is mainly used to view data. So we generate TMG. TMG creates a screen. Using SM30, users can easily maintain the data. Example BranchID Branch Name City B001 Bangalore Bangalore B002 Hyderabad Hyderabad B003 Chennai Chennai If a new Pune branch is opened, the user can directly add it using SM30. No ABAP development is required. Easy Trick SE11 = Create Table SE16N = View Data TMG = Create Screen SM30 = Maintain Data

Real-Time Project Scenario – Plant Configuration Data 1. The client had multiple plants across different countries. 2. Each plant required specific business rules. 3. We created a custom configuration table called ZPLANT_CONFIG. 4. The table stored Plant Code, Currency, Tax Code, and Business Rules. 5. TMG was generated to allow business users to maintain plant-specific settings. 6. Users updated values directly through SM30. 7. The application dynamically read values from the table. 8. New plants could be configured without changing ABAP programs. 9. This made the solution highly flexible. 10. The client appreciated this approach because it minimized future development efforts.
