I am building a flow aggregating multiple excel files into one on a regular basis. I have an Apply to Each step going through each individual file to add to a master, but before I do so, I want to add a random value to a key field if there isn't one.
The problem is, to update a row, you need a key field. Is there a method where I can indicate it is the current row within the Apply to Each step I am referencing?
Hi @Anonymous ,
Since update a row action need a key field and a key value of the row, you couldn't update the row without a key value.
Please take a try with two workarounds below:
1.Update the key field with a value manually in the individual file.
2.Add the rows to the master file derectly, if the key field has an empty value, add the random value.please refer to my screenshot below:
The expression for the Key column "Column4" as below:
