Service contract termination - Generating Credit memo from SC without link to invoice

Hi all,

We are able to generate CM's from SC module, by terminating a contract. When the invoice is already paid in AR, the CM comes to AR interface and gets stuck with error - it is not able to apply the amount on the already paid invoice, as the invoice balance is 0.

I would like to know, if it is possible to generate a CM from SC, without the link to invoice, so that the CM gets generated and applied on the customer account in AR and not on the invoice.

Thanks,
