• What is the cause and solution for SAP error message W0143 - Allow one-time customers is set but "W/o registration" is not ?

  SAP Error Message:
  W0143 – Allow one-time customers is set but "W/o registration" is not
  
  
  Cause:
  This error occurs when the system configuration allows the creation of one-time customers (i.e., customers without a full master record), but the setting for "Without registration" (W/o registration) is not enabled in the sales document type or relevant configuration. Essentially, the system is inconsistent because it permits one-time customers but does not allow sales documents to be processed without customer registration.
  
  Explanation:
  
  One-time customers are customers created temporarily for a single transaction without maintaining a full customer master record.
  The system setting "Allow one-time customers" (usually in the customer master or sales area data) enables this functionality.
  The "Without registration" flag (often in sales document type configuration) must be set to allow sales documents to be created without a registered customer.
  If the system allows one-time customers but the sales document type does not permit processing without registration, the system throws error
