Naming the Transaction
Z transaction types are defined in user-defined code 00/TT. If you create a new transaction, you must define the transaction in user-defined code 00/TT. When you name a new transaction type, the name must start with JDE and can be up to eight characters in length. These examples illustrate a proper transaction name:
JDERR for Receipt Routing Transaction.
JDEWO for Work Order Header Transaction.
