Multiple instances causing clash?

(0) ShareShare
ReportReport
Posted on by 13

We have a flow which reads a file, builds a pdf and attaches it to a personalised email. Sometimes, two instances of the flow will create the same file from the template, even though the file name appears to be a timestamp 22-05-30T04:09:31.6197872Z.docx. This results in the same attachment being sent to different personalised emails, causing a privacy breach. Is it possible that the there are different process threads causing a clash? and if so, can we restrict the process to be just one thread?

    I should have added that the flow is triggered by data being added into a List in bulk.

    Hi @DLACEY ,

     

    You could try:

    1. Click the 3 dots on your trigger
    2. click settings
    3. Enable concurrency, and set it’s value to 1
