New to SAP TM development/coding

Hi All,

I am new to SAP TM development.. We have got a new system (SAP TM) and our functional has done the basic configuration.. Waiting for the PI/XI box to be given for connecting with ECC.. Mean while i would like to know the difference between seeing the transactions in sap tm system and logging with NWBC..

We have created a Freight booking and freight order through NWBC..

I am not able to figure out in which table the freight orders and freight bookings are stored.

I did not find any entry in any of the tables

Why cant we create any transactions in SAP TM system directly...

Can any one let me know how a technical person scope of work differs in TM system with that of NWBC and TM system..

Do we also do coding in NWBC or its always in the TM system.

I saw that certain transactions only execute through NWBC where as they are not valid in TM system.

How different would be the initial set up of master data and creating some transactions.

Kindly help,

Amar
