Business processes are represented in the SAP environment as a chain of transactions. Transactions in a chain often use the results of previous transactions.
The result of a transaction is often in the form of a key (order number, customer number, material, …). Subsequent transactions need this key. The key is usually output in a system message.
When you create test cases, you must often read the result of a transaction and pass it to one or more subsequent transactions. The chain function does this.
This function passes the result of a transaction or transaction screen field contents to subsequent transactions. You cannot chain within a transaction. Results cannot be passed to previous transactions.
If the transaction result is in a system message, it is in the last screen of the transaction.
