Hello Business Central Community,
I hope you are doing great, Let me share a little about the issue that I am here for,
Our client is using the Workflow Approval process for the Purchase entities. In some of the cases The notification comes from incorrect person (user).
Let me share detail information of one incident.
- Here's the first image of Purchase Invoice Workflow. In which we have selected approver type as SalesPerson/Purchase and Approval Chain in Approval Limit Type.

- Now, Second screen shot of Approval User Setup. In that we have user Mayank J. We don't have an value in Sales Purchaser code at this moment in to the Approval User Setup.

- 3rd screen shot of the Purchase Invoice. Below Purchase Invoice is created by Mayank J. and We have added Viral L user as Purchaser Code.

- As a standard procedure, the email should be sent using the Mayank email id (Mayank J). but in this case business central have used random user Harsh M.
- Screen shot of Email Notification which we have received from Harsh M. user. Harsh M user is not included in any of this processes.

Is it a Microsoft bug? or is it a default behavior to use random users? 90% is choosing the right user email, but in some cases we see an odd behavior.
Is there any way to find out the reason behind this incident?
Thanks & Regards,
