Certainly! Here's a detailed explanation regarding the SAP error message VN107 - "Print parameters are determined via customer exit": SAP Message: VN107 Text: Print parameters are determined via customer exit Cause This message appears during the vendor invoice processing or print program execution. It indicates that the print parameters (such as output device, form, print program, etc.) for the document are not determined by standard SAP configuration, but instead are controlled via a customer exit. In other words, the system expects the print parameters to be set dynamically by a custom ABAP enhancement (customer exit), and the standard print parameter determination is bypassed. This message is informational and often appears when the system detects that the print parameters are not set in the usual way but rely on a customer exit implementation. When does it occur? When output determination for vendor invoices or payment documents is customized. When a customer exit (user-exit) or BAdI is implemented to control print parameters
