Referencing a custom structure from a referenced assembly

I am trying to figure out how to share a structure between OS BR files. In an Extender BR file named ExtenderBR I have:   Public Structure MyStruct Public Element1 As String Public Element2 ...
Extenders
Finance

    It's just a namespacing issue. My code above worked because the type was not declared at compilation time, so typing information would only be (successfully) looked up at runtime; but yours wants types available at compilation time, so you have to import the namespace at the top:

    Imports OneStream.BusinessRule.Extender.ExtenderBR.MainClass

    That should solve your compilation issues.

    (For the record, you don't need to mark "Contains Global Functions for Formulas" to go cross-rule, that option is just if you plan to actually reference it from the Member Formula properties on dimension members, something that typically only Finance rules concern themselves with.)

#WorksForMe, dude, at least between Finance rules... I'd suggest to check for typos, there were a lot of them in the code.

I apologize if there were typos, or it appears I cut some corners in attempting to demonstrate the issue.  Below, I will show screen shots using the same hypothetical example.

Here is a screenshot of the relevant portion of the ExtenderBR that is to contain the common Structure & Function:

And since you mentioned it might be an issue with using an Extender for the common Structure/Function, here's a screen shot of the same structure/functions replicated into a Finance Rule file too:

 

And here is its properties tab showing that it has been tagged with having global functions:

 

And now we move on to the Finance rule where I want to use the common structure and function.  In this rules file, I have included calls to both the common Extender and the common Finance rule file to kill two birds with one stone.  I have placed comments on lines 28:36 indicating the compiler issues I receive:

 

And here is the properties tab:

 

As I hope to have demonstrated above, there are no issues referencing the Public functions (and simple variables) defined in other BR files.  I do this sort of stuff a lot with no issue.  But I cannot reference custom structures defined in other BR files.

Any ideas how I can access a custom structure that I have defined in another BR file?

      I can confirm either of the following did resolve the issue.

      Imports OneStream.BusinessRule.Extender.ExtenderBR.MainClass

      or 

      Imports OneStream.BusinessRule.Finance.FinanceCommonBR.MainClass

      Thanks for the pointer.
