Negative amount in invoice

[in...@betabank.de]

Hi, we are trying to make a return invoice and it is negative, we receive this error:
Message Did not save Server Error: Please check your server logs or contact tech support.

We tried with Sales Order also, but negative amounts do not pass through. Is there an easy way to solve this? Thanks!

Hi, thanks for the answer.

It is not really a sales return, it is a new sale only with negative priced items. This corresponds to returnable bottles that the customer was bringing to the shop, but he already payed in a previous invoice for both the bottles and the drinks. We have items with positive prices for the bottles and items with negative prices for the bottles return.
