I have a pretty simple scenario but I'm not sure it will work. I created a custom metadata type for assessment questions sales reps have to do on lead.

Each question has a preferred answer (e.g. it should be "Yes").

I made a screen element w/ several radio components that all use "Yes" and "No" choices.

My hope was I could pull all assessment questions in to collection variable (this part seems to work) and then reference as the Label of each radio button component, e.g. {!QuestionRecordSet[0].Question__c}

Also, I'd later want to compare the screen component choice (e.g. "Yes" or "No") with the record preferred answer in the same way.

Is this possible? If so, how? Is there a better way to do what I'm trying to do? This is currently done with custom objects and apex but we don't need to store any of this data, only a text area with the question and the sales reps answer.

  • each radio button needs to reference a separate record variable (i.e. separate MDT record) as there is no support for indexing collection variables in V46. Fortunately, each MDT query does not burn soql limit – cropredy Sep 30 '19 at 17:50
  • Okay, so just to clarify, you're saying I can't use record collection variables? If so, how would I store each MDT record in a separate variable? Thanks – jameskbw Sep 30 '19 at 18:01
  • you can't index a collection variable in an expression - so either do one collection variable and then loop therein assigning each loop elm to a separate record variable -- or -- do n individual Get Record into specific record variables – cropredy Sep 30 '19 at 18:05
  • Okay, thank you for clarifying. – jameskbw Sep 30 '19 at 18:15

Because (as of V46) you can't index record collection variables, you have two options


  • Each radio button is bound to a singleton recordVariable, perhaps named questionX, questionY, ... Thus, you have n recordvariables


  • Query all the MDT into a record collection variable and then loop through them
  • Use decision elements to assign the MDT to one of the questionN record variable based on the developername of the MDT


Have a sequential series of Get Record elements, each querying a different MDT (using the developername) and assigning to the relevant questionN record variable

Fortunately, MDT queries don't count against your SOQL limits
