I am working on TMG. For this I did as below...
1-- I created a ztable having 3 fields and enter record to that table.
2-- from utilities->TMG, I provide authorization group and function group as table name, and maintenance type is one step.
3-- I clicked on create button to create the TMG.
4-- From se80 I activate the function group .
Now for test the TMG, I opened sm30 and enter my table name and clicked on maintain button.Then its showing I have records in Table but when I clicked on new entries to enter new data, its directly come out from there and again showing the sm30 initial screen with a message one 1 record chosen.
So could you please help what should I do to entries new entries there ?
