Menu Combination of H and C in Finacle

In our Department of Posts Savings Branch is now migrating with Finacle version 10.2.13. In this latest version of Finacle Menu's were configured in two types of combination i.e
example : Transaction Maintenance
HTM

CTM
Both above menus for Transaction Maintenance. HTM is an Finacle default menu. Default Menu's are starting with H. Some of the menu's are customized for DOP requirement i.e Customized Menu starting with C. 


here HTM is used to do the transaction between Office Account / Office Account to Customer Account or Reversal Process. 

CTM is for Customer account Transaction i.e Deposit / Credit. It is also used to do the UCR Transaction.
