What is TMG in SAP ?

 TMG is a tool to create table maintenance program by which we can create, edit and delete data in large chunks in a table. The main purpose of the table maintenance generator is to create/change and delete the table entries.

We can transport TMG data by enabling standard recording routine. An end user can access TMG with Tcode

Single Step: Only Overview is created that means the TMG program will have only one screen where we can add, delete or edit records.

Two Step: Two screens namely the overview screen and single screen is created. The user can see the key fields in the first screen and can go on to edit further details.

In this the overview screen contains only the key fields and the single screen contains all the fields. On a single screen we can only maintain the screen. Like delete and insert. We cannot update from a single screen. From the overview screen we can delete and update.

There are 39 events for Table Maintenance Generator.
