SQL data w/ Allowed Values & Explicit Column Selection

If Explicit Column Selection is enabled, it breaks the use of SQL tables sourcing dropdowns. Generates the following error:

 

"The requested operation is invalid. Server Response: The column 'Value' of the table wasn't found. inner exception: The column 'Value' of the table wasn't found."

 

Please do not turn this feature on for all apps until this is fixed.

Re: SQL data w/ Allowed Values & Explicit Column Selection

Hi @rgius,

 

Thanks for the feedback.

 

This is a known issue.

Please turn off this option for a temporary workaround if you are currently working with SQL Table in PowerApps.

 

Regards,

Michael

Go to File > App Settings > Advanced Settings.

You may need to save, close, and reopen studio for it to take effect.

Re: SQL data w/ Allowed Values & Explicit Column Selection

Hi, what's the status with this issue? I'm facing the same problem with the Explicit column selection feature turned on. The feature is now listed under Preview Features saying "These features will be turned on for all apps soon..."  So, I'm just wondering when will this happen and is the feature at it's release state currently or are there some fixes still ongoing?

 

The requested operation is invalid. Server Response: The column 'Value' of the table wasn't found. inner exception: The column 'Value' of the table wasn't found. clientRequestId: 65584ead-b265-4cfe-8a80-29ad5c887437

 Did you try File > App Settings > Advanced Settings.

Above steps will resolve the problem. I am not sure where Microsoft is at on resolving this.

Re: SQL data w/ Allowed Values & Explicit Column Selection

Yes I did and that workaround is ok for now. I'm just wondering the indication: "These features will be turned on for all apps soon..."

So, when they do that, the workaround is no longer valid.

Hopefully they'll just exclude the functionality from incompatible sources - like delegation.

Re: SQL data w/ Allowed Values & Explicit Column Selection

Is there an article or link that explans exactly what this does and what data sources it is confirmed to work with? The setting just says:

 

 



Target data source must support this feature

But I've been unable to find what target sources do support it.
