Check the TMG in SM30 Tcode

Follow the below steps to check whether the TMG has been created already or not for the table.

Step-1:

• The first step is to check transaction code sm30 to confirm whether TMG is already created or not. Open SAP ABAP, Type sm30 in the search box and hit enter.

• Type the existing table name and check by clicking the Display option. Here I’m taking a previous table ztsi and when I try to see the TMG for this table it’s not showing so TMG is not created for this table.

Since it is not created earlier. So, TMG is not visible to us.
