Knowledge Management

Question:
We are planning to use barcode scanner in inventory management and encounter following problems:
1. The barcode will maps to batch number in the system,but the length of barcode is 18,but the batch number is 10 digits. We are planning to do development to cut the barcode to 10 digits before input it into the system. Is there better solution for this?
2. We will use batch input for all the possible transactions such as MB1B,MIGO,etc. Is it possible to call function directly instead of using batch input?
Your heip will be highly appreciated!
