The source resource and filters are available in the data flow properties list. Follow these steps to set up an expression:
- Right-click on the data flow canvas and select the Properties menu.
- Scroll down and find the property named like [REST Source].[Resource]. This is the property containing the resource.
- Scroll down and find the property named like [REST Source].[ResourceParameter]. This is the property containing the resource parameters. The property is a string combination with format [name]=[value]. Each value is separated with a newline (\n).
- Scroll down and find the Expressions property. Set up an expression to modify the resource or parameters dynamically.
The composite record output contains not only fields from the composite record, but also the parent records. The output will be populated with sets of rows, one set for each parent record. Each set of rows is separated with blank row (all NULLs).
- New: Component setup dialog now includes data Preview tab.
