Table Maintenance Generator (TMG) is a tool which is used to create a equipment by which customized tables created by end users can be changed as required,such as making an entry to that table,deleating an entry etc.

SM30 is the transaction code to create table maintenance generator.

Go to SE11, give the table name and click on change. Then Go to utilities--> Table maintenance generator.

In the table maintenance generator screen, we should give Authorization Group, Function Group name (Function Group name can be same as table name), Maintenance type can be one step or two step, usually we will create with one step. we should give maintenance screen number. After clicking on create button, a table maintenance generator will be created.

To check it go to SM30 . In SM30, we find display, Maintain options.

We can view the table contents by choosing Display and we can create table entries by choosing Maintain.

Why we have to go for Table maintenance generator, when we can edit the table by SE16 or SE11, utilities->create entries?

In the production system, end-users will not be having access to transaction codes like SE11 and SE16. Developers will not be having access to many transaction codes including the above two.

To view the contents of the database table, we will use SE16n in Production system. Please find out the difference between SE16 and SE16n.All these authorizations will be maintained by BASIS team, by creating access profiles.

So in order to edit or create the contents of a database table, we should go for table maintenance generator. In real time, authorizations will be maintained in production system. (even in development and Test systems to some extent).

There is an audit like Sarbanes-Oxley Act for American clients, where every thing will be audited by government agency. To know more about SOX, use the links on the right hand side of this page.

The second reason is, we can edit or create multiple entries at a time, using table maintenance generator.

Apart from that we have options like 'Enter conditions' in table maintenance screen SM30. Please try to find out the use of those, by creating an example.Table Maintenance generator: Difference between one step and two steps.

While creating table maintenance generator, we find below options:

1. When we choose one step, we have to give the screen number in Overview Screen field.

2. When we choose two step, we have to give both overview screen number and single screen number.

You can give any number for screen. Don’t give 1000 screen number. As this number is reserved for selection screen.

When we choose two step, two screens will be created for table maintenance. For single step only one screen will be created.

When we choose two step, table maintenance will work as follows:

Go to SM30, give the table name for which you have created table maintenance-

Overview screen will be displayed. To create entries, when you click on ‘new entries’.

Another screen will be displayed, where you give input and save.

You can enter one record at a time.

We use single step generally, as it is user friendly.

To completely understand the difference and above points please do exercise by creating table maintenance generator in both ways (using single step and two step).

Hi saritha pyla,

Both are silimar SM30 and SM31

there is no difference between them.

With the help of the table maintenance generator, you are able to maintain the ENTRIES of the table in SM30 transaction.

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.

Best regards,

hi check this..

There is absolutley no difference since both are based on the same program SAPMSVMA and screen 100.

However, within the programs there is some internal SAP processing based on the tcode (SM30/SM31) SY-TCODE however it does not /should not impact us developers.
