Input

All processing functions, write and adapter functions as well as query functions have an input. The input connects the function with a preceding function.

You can configure specific selections to restrict the data transferred from the Input function, and can configure mappings to adapt the data to the required signature of the function. The latter also helps if the function rules are based on a function template and different data with different fields needs to be processed based on common rules.

In contrast to the data that comes from lookup, the data that comes from the input is the basis for the business event and error management, including partial restart capabilities.
