Error "Posting period &1 &2 not open for variant &4 and ledger &3" occurs when canceling the billing document using the API API_BILLING_DOCUMENT_SRV.

SAP S/4HANA Cloud Public Edition

One possible cause is that the posting period is closed. And the API does not support any date related parameters for the canceling billing documents. 

• Open posting period in the "Manage Posting Periods" app to allow posting in order to use the API to cancel the billing document.    
• If not opening the posting period is what you intend, then this scenario is not supported and the error is expected. 

• Cancel Billing Document
