Incrementing a DateTime Variable within a Do Until Loop

(0) ShareShare
ReportReport
Posted on by SaltySeaDog 37
I have a Do Until loop where I want to add 1 day to a variable 'CurrentDate', which has been initialized outside of the loop. I am using the Set Variable with addDays() to add the day to the CurrentDate variable, but when I save the flow, I get the following error:
 
Flow save failed with code 'WorkflowRunActionInputsInvalidProperty' and message 'The inputs of workflow run action 'Set_variable' of type 'SetVariable' are not valid. Self reference is not supported when updating the value of variable 'CurrentDate'.'.
 
Any ideas on what I am doing wrong?

    Hi! Unfortunately, you cannot use self-reference inside the addDate() function, but I have an idea for you.

    How about using an additional integer variable called NumberOfDays? You need to initialize it outside the loop with a zero initial value. Then you can increment it inside the loop using the "Increment variable" action. After that, you can use the "Compose" action to add this incremented number of days to your CurrentDate. The formula in Compose action:
     
    addDays(variables('CurrentDate'),variables('NumberOfDays'))
     
     My test flow looks as follows:
     
     
    Let me know if this works for you!
