Setting Inputs

The inputs required by the processor are calculated automatically from the configuration of the base processors. Note that where many of the base processors use the same configured input attribute(s), only one input attribute will be created for the new processor.

However, if required you can change or rename the inputs required by the processor in the processor design view, or make an input optional. To do this, click on the Processor Setup icon at the top of the Canvas, then select the Inputs tab.

In the case above, two input attributes are created - Title and Forenames, as these were the names of the distinct attributes used in the configuration of the base processors.

The user chooses to change the External Label of one of these attributes from Forenames to Forename to make the label more generic, and chooses to make the Forename input optional:

Note that if an input attribute is optional, and the user of the processor does not map an attribute to it, the attribute value will be treated as Null in the logic of the processor.

Note:

It is also possible to change the Name of each of the input attributes in this screen, which means their names will be changed within the design of the processor only (without breaking the processor if the actual input attributes from the source data set in current use are different). This is available so that the configuration of the member processors matches up with the configuration of the new processor, but will make no difference to the behavior of the created processor.
