API browser of generalInvoiceRequest430 COM module


/images/arrow_right.png IGeneralInvoiceRequest::SetCredit method
Sets the optional credit object reference parameters. This object reference is only set if such a credit request was generated and accepted prior to the invoice generation.

The credit, invoice and reminder object references (if supplied in the request) form a object reference chain (credit -> invoice -> reminder) with the reminder as topmost object reference if supplied in the request otherwise the invoice is the topmost object reference (the invoice object is mandatory in all cases!). The page "object reference" provides an in-depth description of the concepts of "object reference", "object reference chain", and "topmost object reference".
