Use Loop node to access repeating data
You can look through the repeating data within a data object variable and process the contents of each row.
In a Loop node, you can map a list field of a data object to the Complex variable property. If you select the return type as Child level, the corresponding columns are displayed, and the column names are updated to match the fields in the list.
The Loop node can then be used to iterate through the rows in the list to get data from it.
For a detailed example of how a Loop node is used to access repeating data, see Access data in a nested list.
