Patching a single CDS item in a gallery should be simple... but it's not.

I need to update a CDS D365 text record each time such item becomes selected via a checkbox in a gallery. To test my approach, I use a hard coded text value in the following formula, but PowerApps keeps saying the function path contains invalid argument. I've read other articles on patching, but it remains a mystery why something so simple doesn't work... Thanks for your help in advance..

Patch([@Projects],ThisItem,{msdyn_description:"test"})

You are very close, is msdyn_description a column in your Gallery?:
Patch([@Projects],ThisItem,{msdyn_description:"test"})

Hi @testasdfasfsafa

If you have a required field in your entity, you will need to patch it as well. If you have an Autonumber field that is required, you will need to uncheck required.

Thanks for your help. No, "msdyn_description" is an internal column name in D365. Should the column value in curly brackets be the display name of the column or the internal name? Perhaps, that is what is wrong? The documentation related to those details are non-existent.

Actually, I just replace the internal name with display name for the column in curly bracket and no difference 😞

Inexplicably, when I hover over the error, now I get a little more details... It's complaining about a column in the schema that I'm not trying to update.

I can't believe this... I just replaced CDS source with the same Dynamics 365 and it's working just fine. I'm so nervous about Microsoft replacing D365 with CDS, there are so many issue that I have encountered... 😞

If it is part of the internal column, its ok.
On the error message,
Is the specified column in the error is a required column. Either you add it to the Patch or Make the column not required in the table
