If your process flow is sending source data into a target connection, you should map this data using the map shape. This is done in the usual way with two points to note:
In a typical situation, the map shape is used to map data from a source connection to a target connection. However in this scenario, we don't have a source connection - Patchworks doesn't know what data you are sending in or what system it's coming from.
As such, you won't select any source details when configuring the map shape - just leave these field blank:
Because Patchworks has no way of knowing the structure of your incoming data, mapping rules must be added manually.
