Is there a way to use fields from a parent section in a data model to calculate a field.

Aston

For example,

ParentSection
          ParentField
          ChildSection
                         ChildField

Could I somehow use IIF(ParentField="string", 1, 0) as a calculation for ChildField, because right now I can't reference parent fields in the calculation? I can only reference other ChildSection fields.

 Setting your calculate expression to: ParentInstance.ParentSection.Fields("IN Product Code").Value 
should correct your issue. As we are referencing the field name directly we should be using the exact spelling of the name and should not need to use underscores instead of spaces, also the "N" should be capitalized in the field name as well.
As you can see in the updated screenshots below the Child Section with the underscores does not work but the Child Section 2 without underscores does.

This is really the place where this info should be. https://wiki.grooper.com/index.php?title=Expressions_Cookbook

However, I see a note that the article is still in progress and traversing the data model's hierarchy is one of the things needed. @Brian is this something you could help with in the mean time?

@Aston
Does this Calculate Expression help with your issue of not being able to reference Parent Fields?



Below is the output showing that the value from the ParentField from the Parent Section can be referenced to populate the ChildField in the Child Section.

This is still not working for me for some reason. I am trying to populate "In Product Code2" with "In Product Code"'s value.

This works. Although it doesn't work when I run test extraction, but it does when I run the actual extraction process.
