Loop End (3 ports)

Options

Row key policy

How should row keys, which must be unique, be generated in the output table? ' Generate new Row IDs ' generates new row IDs sequential in the form Row0, Row1 etc.; ' Unique Row IDs by appending suffix ' appends '_Iter#' and the iteration number to the incoming Row ID; ' Leave Row IDs unchanged ' leaves incoming Row IDs unchanged. Nodes which previously had 'Uniquify Row IDs' set, will follow the second option

Add iteration column

Adds a column to the output table containing the iteration number, starting with 0

Ignore empty input tables

Selecting this option means the structure of empty input tables at the specified port will be ignored and they will not cause the node to fail

Allow changing column types

Tables in which the column names remain constant, but the types change between iterations will be allowed to pass. The type of columns changed will be the simplest type common to all input types. A message will be sent to the console explaining any failures

Allow changing table specs

Tables in which more complex changes to the table structure occur will be allowed to pass. This setting overrides the 'Allow changing column types' setting. If this option is not set, a message will be sent to the console explaining any failures.
