Hello viswa1011
There is really not need to memorize transaction codes and tables. Focus on learning functionalities in your area, in QM. You may want to switch on display of technical names in the Extras -> Settings of the SAP menu. That will display t-codes in the menu tree and will soon memorize the most used t-codes.
You can display all t-codes in SE93 and all tables in SE11, but again don't use those transaction to memorize. Knowledge of t-codes and tables is a byproduct of experience. You will get there in time.
