Thanks Rajkumar,
I believe these tables are not regular SM30-View tables.
You can either use se16/se16n to display the table contents instead of SM30, because view or TMG(Table Maintenance Generator) is not created for all the tables 
.
What is the best what to see/check their properties other than this.
If you want to find the table for the particular screen field, you can use F1 on the field and can get the table information, but for some fields if it is mapped with structures, it is tough to get the table name, in order to get the table name, you can use multiple methods like where use list method or Trace method.
Please find the document below to find the table name for field
How to find Table name for a Field which is shown structure name on press F1.
