Avoid duplicate check between MM and FI invoices

[former_member542366]

Hi!

My client has the following situation:

- They created a PO and a related MM invoice,
- Decided that the process should be FI, and reversed the MM invoice,
- Tried to post an FI invoice, but with no success, as they are getting a duplicate error.

Is there any way to deactivate the duplicate check between MM and FI invoices?

Thanks

That is a bad business practice to deactivate that check; that would not be approved by the auditors. They can change a character in the reference field to get past the duplicate check.
