There are two ways to maintain Data records in a table :
1. By program : using insert/delete/modify or update statement.
2. By table maintenance
What is the advantage or disadvantage of one process to another.

Hi,
Table maintenance is used to maintain data in the tables created (ZTABLE)
Generally for inserting new records into custom table thru transaction SM30, we need to enter all the values manually and save the record.
When certain data for the key fields needs to be populated automatically while creating entries, the steps involved are:
Maintaining the subroutine in view V_TVIMF for a particular custom table.
Logic for extracting relevant data for the fields entered, when user press enter button.
Check this blog for more information on extracting data in table maintenance.

With the help of the table maintenance generator, you are able to maintain the ENTRIES of the table in SM30 transaction.
It can be set in transaction SE11 - Tools - Table maintenance generator.
Table maintenance Generator is used to manually input values using transaction sm30
follow below steps
1) go to se11 check table maintenance check box under attributes tab
2) utilities-table maintenance Generator-> create function group and assign it under
function group input box. Also assign authorization group default &NC& .
3) Select standard recording routine radio in table table maintenance generator to move table
contents to quality and production by assigning it to request.
4) Select maintenance type as single step.
5) maintenance screen as system generated numbers this dialog box appears when you click on create button
6) save and activate table
One step, two step in Table Maintenance Generator
Single step: Only overview screen is created i.e. the Table Maintenance Program will have only one screen where you can add, delete or edit records.
Two step: Two screens namely the overview screen and Single screen are created. The user can see the key fields in the first screen and can further go on to edit further details.
SM30 is used for table maintenance(addition or deletion of records),
For all the tables in SE11 for which Table maintenance is selected , they can be maintained in SM30
Sm30 is used to maintain the table ,i.e. to delete ,insert or modify the field values and all..
It creates the maintenance screen for u for the particular table as the maintenance is not allowed for the table..
In the SE11 delivery and maintenance tab, keep the maintenance allowed..
Then come to the SM30 and then enter the table name and press maintain..,
Give the authorization group if necessary and give the function group and then select maintenance type as one step and give the screen numbers as system specified..
Then create,,,
Then u will able to see the maintenance view for the table in which u can able to insert and delete the table values...
We use SM30 transaction for entering values into any DB table.
First we create a table in SE11 and create the table maintenance generator for that Table using (utilities-> table maintenance generator) and create it.
Then it will create a View.
After that from SM30, enter the table name and Maintain, create new entries, change the existing entries for that table.
