Dear Team,
I have followed the below steps within the last 3 days many times, and yet the output column is empty.
> DataFlow has 2 different data sources.
1- PL/SQL Query which has 27K rows
2- User Created Table which has 9K Rows
and merged both data under the name "Merge" with Left Join and add a single column "ACTUAL_ARRIVAL_UTC"
DataFlow refreshed in 15 seconds successfully.
> The training has been accomplished successfully
1- ModelName: "DeliveryPointETA" with "360 Min Training"
2-"DeliveryPointETA Training Data" and "DeliveryPointETA Testing Data" have been created successfully.
3- Status = "Trained" (Took 16min)
4- Type = "Regression"
5- Model Training Report created and Performance is %86
> Then applied the model with the following details:
1- Input entity is selected "Merge"
2- New output column name "DeliveryPointETA"
3- "Merge enriched DeliveryPointETA" and "Merge enriched DeliveryPointETA explanations" have been created successfully
4- Applied model refreshed successfully (took 55 Min)
> When I have checked the Result columns they are all empty:
1- "DeliveryPointETA.RegressionResult" is empty
2- "DeliveryPointETA.RegressionExplanation" is empty
3- "DeliveryPointETA.RegressionIndex" is populated.
Since the RegressionResult column is empty unable to predict the data at all.
Can you please advise?

Hi @Anonymous,
If you do not apply merge operations in your entities, did these fields appeared?
BTW, it seems like you are creating a computed entity. Do you work with premium license that has premises to use this type of entity? Using computed entities on Power BI Premium

Hi,
shortly I am part of the Premium License and using it accordingly.
Also within the exact same way I did create 2 ML Model successfully and working fine.
The only different could be the cardinality of the training model, my previous records were around 10-17K but this time I did increase 40K.
Rather than that the rest is same.
Any further advise?
HI @Anonymous,
Maybe you can submit a support ticket to ask power bi team to check the backend requests to get further supports, it is free to pro and above licenses.
submit a support ticket
