Unable to access Multi Row Variable Set values in Flow Designer – Grayed out in Create Catalog Task

[Community Alums]

Hi Team,

I have a Catalog Item where I am creating a Catalog Task (sc_task) using Flow Designer.

For normal catalog variables, I am able to populate the values in the Description field of the Catalog Task using:

Trigger → Requested Item → Variables

However, I have a Multi Row Variable Set (MRVS) on the catalog item.
When I try to access those variables inside the Create Catalog Task → Description field, the MRVS variables are grayed out and not selectable in the data pill picker.

Requirement:

After the catalog item is submitted, I need to display a variable value from MRVS in the Description of Catalog task.

Thanks! I’m also sharing a blog I wrote on this topic — “How to Safely Calculate Percentages in a Finance Flow Designer Using MVRs and Set Cost Centers”.
It demonstrates the same approach with inline scripts (f(x)), looping through MVRs, and safely handling percentage calculations. I hope it will be helpful for others working on Finance flows 👍🙂

Hello @Community Alums ,

First of all you will need to extract the MRVS values, so you can use this approach :

1) Create a custom action and pass your mrvs variable from Get Catalog Variables step taking input as json: 

2) Inside the Action use script step so their you can send your values as output to display a variable value from MRVS in the Description of Catalog task : 

If my response helped mark as helpful and accept the solution.

Multi Row Varaible set will retrun in Array of Object, so use for each loop and iterate then you can read the elements in it
