Billing - Credit memo at IS-H

Dear all,

regarding the billing process at patient management at ECC6, is there a way to issue a credit memo instead of canceling the invoice?

The steps followed are entering transaction NP10, calling the case and proceed with billing. The request is to issue a credit memo afterwards for the patient on that invoice instead of cancelling it, either from NP transaction of from another procedure.

Thank you in advance,

I.
