Excel Update a row error 400

Posted on by jlwhittaker 4

I am trying to build a flow that updates an Excel table at each step, I've managed to get it to successfully modify 2 columns.

 

But it fails to modify anymore just gives the following error....

 

{
  "status": 400,
  "message": "Maximum number of identity column variants for a single table exceeded. Current '2', Maximum '2'. Up to '2' column name variants should be in use across workflows for one particular table.
  "error":

}
 
Can only 2 columns of an excel table be modified in a flows run?

    Hi @jlwhittaker ,

     

    I found a thread where said the same issue:

    Solved: Get Row Error 400 max ID columns exceeded - Power Platform Community (microsoft.com)

     

    According to the error message, I assume that in one flow you cannot update a same table twice for the same record. If possible, please share your flow with detailed steps in screenshots, or you can try and merge the update a row actions.

     

    Best regards,
