Excel Online (Business) - What is Key Value?



I got problem when creating Flows. When I need to update rows in excel file action ask me to fill Key Value when I fill it with suggested dynamics content I got error 404 that resource was not found. Also when I type string to this form also I got error 400 that value must be provided. I am really curious where the problem is as I try all things. Also I typing expression by my own but also then received 400 error. This action working in Apply to each rules but didnt work also without it.

Hi @KamilTee ,


Could you please share a screenshot of the configuration of your flow?


Have you created a flow as screenshot below:



The "Key value" field require a value of the Key column.

Please choose the "Key column" Value dynamic content in the "Key value" field.


Also please make sure the  "Key value" would always be unique to find a corresponding row in the excel.


Best regards,

Yes all flow is created as on below picture, also the value in the Key value field is selected from the dynamic content and under it its got following value "items('Apply_to_each)?[Status]" and still it doesnt work: 




Also now after test I got error 404 NOT FOUND. Which is really curious as every earlier step are executed on the same file. 




Best regards
