Elasticube - "Refresh Schema" error

[vaibhav_j]

When I click on the "Refresh Schema" option on an Elasticube, I get the following alert message:

Refreshing Schema: Differences detected

The following differences were detected between the current schema and the updated schema:

<followed by a list of every column in the Elasticube> null

1. Why am I getting this alert message?

2. What does it mean? 

3. How can I avoid this alert in the future?

See attached screen shot for reference.

Thanks!

Details on the specific error can be found in this article

To void this alert moving forward, I would recommend proactively refreshing the table connectivity settings in the elasticube once any changes are made on your database end.

Hope that helps!

@Diane_Kostka Thanks for your response and the link to the article. Is it OK (safe) to select "Apply" on the alert message and then continue to proceed with the build? Every time I select "Refresh Schema", the message pops up and subsequently the build fails.
