• What is the cause and solution for SAP error message CZ286 - Document type and invoice reduction document type must be different ?

  The SAP error message CZ286 indicates that there is a mismatch between the document type of the invoice and the document type of the invoice reduction document. This typically occurs in the context of invoice processing, particularly when dealing with credit memos or invoice adjustments.

  Document Type Mismatch: The error arises when the system expects the document type for the invoice reduction (e.g., a credit memo) to be different from the original invoice document type.
