Hi @answeriver :
Could you tell me :
- When a specific field is changed to "accept", do you want to send a notification to the user who created the record?
- Whether each record in the data source has a field containing the email address of the creator of the record?
- Can the operation of changing the value of the specified field be "Accept" only in this app?
I assume the above assumption holds.
Firstly,If my above assumption holds I suggest you take @Drrickryp 's solution.
You only need to put the code to send the email after the code to modify the specified field to "Accept". Then send the email to the creator's mailbox saved in the record.
Secondly,I suggest you migrate the data to SharePoint list, because excel has many restrictions.
There are three following benefits:
- High degree of automation:Can automatically detect whether the target field has changed through flow and trigger the specified event.
- Support delegation function:By default, if there are more than 500 records in the excel data source, problems will occur
- No need to manually save record creator information:Automatically save the information of the creator of the record in the default field ‘Created by’.
Finally,I've made a test for your reference:
My data source(Share Point List):'List A'
Column (click to edit) Type
I assume ‘status’ is the specified field.
1\Create a flow
