• 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 W0143.
  
  
  Solution:
  
  
  Check Sales Document Type Configuration:
  
  Go to transaction VOV8 (Change Sales Document Types).
  Select the relevant sales document type (e.g., OR for standard order).
  Check the setting for "Without registration" (W/o registration).
  Ensure this flag is set if you want to allow one-time customers for this document type.
  
  
  
  Check Customer Master Settings:
  
  Verify that the customer master or sales area data allows one-time customers.
  This is usually controlled in the customer master data or sales area data settings.
  
  
  
  Align Settings:
  
  Both settings must be consistent:
  
  If Allow one-time customers = Yes, then W/o registration must also be enabled in the sales document type.
  If W/o registration is not enabled, then one-time customers should not be allowed.
  
  
  
  
  
  Adjust as per Business Requirement:
  
  If your business process requires one-time customers, enable "Without registration" in the sales document type.
  If not, disable the "Allow one-time customers" setting.
