Append Fields Tool
The Append Fields tool appends the fields of one small input (Source) to every record of another larger input (Target). The result is a Cartesian Join where all records from both inputs are combined.
Connect inputs
The Append Fields tool accepts two inputs:
T anchor: Target. The larger data stream that records are appended to.
S anchor: Source. The smaller data stream provides the records that are added to the Target stream.
Configure the tool
Use the table to modify the incoming data stream. Each row in the table represents a column in the data.
Warn/Error on Too Many Records Being Generated: Since the Append Fields tool is performing a Cartesian join, you can unintentionally produce an excessive amount of records. You can configure warnings or errors to be reported to ensure too many records are not produced.
