Concurrency and Unique Variable

(0) ShareShare
ReportReport
Posted on by 76

Hi- I have a flow which uses concurrency control as shown below.  The problem is that the unique variable that I want to establish for each instance is not occurring.  The variable uses a values from an excel spreadsheet in conjunction with UTCnow().  When I run the flow my UTCnow() value never changes.  Is this an expected outcome for "concurrent flows"?  If so, is there anyway to make each parallel flow unique?  I need a unique value for each concurrently run leg so that I can update an excel spreasheet later in the flow. Unlike a parallel action which I could add a delay to, I expect I do not have that option here. Thanks!

    Consider the use of the guid() function to create a reliable unique ID instead of utcnow()

    Using the guid() function did not work.  See output to excel for the two concurrency legs that are run at the same time - they are identicle.

    Here is my flow with the guid() function.  Still having issues creating a unique value for the variable UID within the Apply to Each 4 step.  Again, I think the issue is that because I have applied the concurrency option, it is not working.

    Yes, that is because you are setting the GUID in a variable. You don't need a variable. Use the guid() function directly inside of your add a row into a table action. Then it will be unique.
