Excel Update Row Error Message: Max Id columns count for a single table exceeded (2)



I am trying to build a flow that pulls data from multiple CDS entities. I have to look up using 'List Records' and then update the row on an excel spreadsheet. There are only 8 columns on the excel spreadsheet table but I keep getting the Max ID Columns error above in the subject.


It seems odd that there is only a max of 8 columns supported on an update row action.

I can't use sharepoint lists or CDS because I have to use a custom GUID to compare the key columns. 


Please help!

Hello @CBI_Oshin,


You should be able to update a row with more than 8 columns using the update row action.

To update a row, the flow does require the key Column and value.

Can you please share the error message.
And a picture of the excel connector. It’s hard to see the connector so zoomed out
It sounds like the key column is the one with the error.
