If your company has applied the duplicate expense detection policy rule to your account, then the system may flag or block certain expenses if they are deemed as duplicates.
The policy rule can be set up as a warning, which will appear if any duplicate expenses are detected when you submit your expenses. Clicking Continue on the policy warning will allow you to submit these expenses and they will be reviewed by your approver and/or finance team.
If the policy rule is set to block, then you will not be able to submit any expenses the system has flagged as duplicates. You need to speak to your company finance team and ask them how they would like you to proceed.
For more information on how the system determines if an expense is a duplicate, please read our What is a duplicate expense help article.
