Dear Community

Yesterday we observed that a Sales Invoice containing one single Invoice Line appeared in the Sales Invoice List with a negative total amount.

We have only one Person working in the Accounting. The Invoice was not added manually by this Person.
We tried to find out the source, but did not succeed. We ended up in deleting the Invoice. Unfortunately it appeared today again without any action from anybody from our Team.

Does anyone there have an Idea what else could be generating this Invoice?

Any help will be much appreciated!

Thanks

Do you have any jobs that automatically imports or creates sales invoices?

Have you had any customizations added to your system recently?

You can check which user created the sales invoice if you click CTRL+ALT+F1 on the sales invoice and inspect the fields on the record.

Maybe that will give you a hnt?

Hi Inge,

Thans for your response. I don't know if the Invoice is User or System generated. I don't have access to the environment because I am employed in the company and have limited access due to privacy and Data protection reasons. I will see with the Accountant which user is behind this entry and follow up on the Billing process behind the original Invoice. Maybe I will get closer to the source of this issue.

This Invoice started apprearing after some corrections were made due to a wrong payment amount from the customer that pais 2 cents more than the Invoiced amount of the original. The Corrective entries are correct and balanced out. No open balances related to the wrong payment and original Invoice. But after issuing the corrections this Invoice with the same amount of the original Invoice but negative is being generated for no reason. Deleting doesn't help because it appears again after a while.

Maybe it is being generated due to something that went wrong while correcting the incomming payment? Any Idea what could have been?

From Inspecting page / table fields You should be able to see who created it and when.
If this invoice is being created at the moment of posting correction - please give some more details how this correction is created.

Otherwise - You can also activate Change Log and add monitoring to table 36 and 37 - to get more details when an entry is created here.
