Posted on by perksyaus

I am running a flow where I am extracting data and adding rows into an excel table. I am then taking a key field from my extract and using this field into a PowerBI query to return two other variables which I want to then update the row in excel that I have just added.

the query returns the correct data and I map it to a variable using the select statement - but when I go to update the row in excel it does not update - it

I'm not sure what I am doing worng.

Hi Denise,

You need to write an expression to get the value of 'ProfitCentre' property from the output array of Select action.

Here are the detailed steps to extract the value from Select action output:
1. Click & select the column to update in the excel, here I have chosen Serial# column to update.
2. Next, we will select 'Expression' option and type the below expression in the expression textbox. First() formula will get the first item of an array and then we will pull out 'ProfitCenter' value using indexer:
first(body('Select'))?['ProfitCenter']
3. Click, save & test your flow

If this helps & solves your problem, please remember to give a 👍 and accept my solution as it will help others in the future.

Thanks

Re: Update row in Excel using dynamic content is not adding fields into row

Thanks for the reply: the output from the select returns as an array:

[
{
"Material": "1557LV",
"ProfitCentre": "1TR007LV00"
}
]

I just require the value to be updated in the Excel row - but I can't get the syntax right to access the value in the array - any help would be grateful

Re: Update row in Excel using dynamic content is not adding fields into row

You are using the Variable in multiple steps, but that doesn't change the variable. You could use the Variable in 10 different steps and it will remain the same, that is the purpose of using a variable.
You set a Variable to be a value, and then when you use the Variable throughout the flow, it will remain that same value.

The only way to change a Variable is to use another Set Variable action or Append to Variable action.

Hi @perksyaus

You can get the value of 'Profit Center' without using variable. For that, you don't need to write the variable name in Map key inside select action, just type the plain text 'ProfitCenter' as shown beloe:

Once it is done, then you can write the below expression in the Update row action to save that value in excel sheet:
first(body('Select'))?['ProfitCenter']
