Dataflow gen 1 refresh error

[robertCollect12]

Hi, 

I have 3 workspaces

Dev - PPU licence
Test - Pro licence

Prod - Pro licence

I have Gen 1 dataflow with computed tables in DEV workspace and reports that connects to this dataflow in PROD workspace.

Im getting refresh error : 
DataSource.Error: Downstream service call failed with status code '403'.. Microsoft.Data.Mashup.ErrorCode = PowerPlatformDataflows018. Error = Premium caller trying to read premium per user information.. ErrorCode = PPUInformationNotAllowedForPremiumCaller. 

Thanks

Robert

Hi @robertCollect12 

“PPUInformationNotAllowedForPremiumCaller”
means that your Pro-licensed workspace (Prod) is trying to access a PPU-only feature—in this case, a Gen1 dataflow with computed tables from your Dev workspace, which is under a Premium Per User (PPU) license.

Here’s the catch: Pro workspaces can’t consume content from PPU workspaces, especially when it involves premium-only features like computed tables in Gen1 dataflows

1. Move the dataflow to a Pro workspace
   If possible, recreate or migrate the dataflow to your Test or Prod workspace (both Pro). But note: computed tables are a premium feature, so they won’t work in a Pro environment.

2. Upgrade the Prod workspace to PPU
   This is the most straightforward fix. Assign a PPU license to the Prod workspace so it can access the Dev dataflow without hitting the 403 error.

3. Switch to Gen2 dataflows
   If you're open to reworking your dataflows, Gen2 dataflows offer more flexibility and better integration across licensing models.

4. Consolidate under a single license model
   Keeping all workspaces under PPU or Premium Capacity avoids these cross-license headaches.

Thank you @ribisht17 
I can't use Gen 2 because I dont have Fabric.
I want to assign power bi pro licence to report viewer and not ppu licence to lower the cost. I guess I will have to avoid computing tables in dataflow. 

There are no other alternative ? 

thank you
