• What is the cause and solution for SAP error message W_CB173 - Enter a customer or a customer list ?

  SAP Error Message:
  
  W_CB173 – Enter a customer or a customer list
  
  Cause:
  This warning message appears when a transaction or report requires you to specify a customer or a list of customers, but you have not entered any customer number(s). The system expects at least one customer to be entered to proceed with the processing or selection.
  
  When does it occur?
  
  When running reports or transactions that filter or process data based on customer master data.
  When selection criteria require a customer or customer list but the field is left blank.
  For example, in sales reports, billing documents, or customer-specific data extraction.
  
  
  Solution:
  
  Enter a valid customer number in the customer field.
  Alternatively, enter a customer list (range or multiple customers) if the transaction/report supports it.
  If you want to process all customers, check if the transaction allows leaving the field blank or using a wildcard (e.g., *), or use the appropriate selection option like "All customers" if available.
  Verify the input fields and ensure that the customer data is correctly entered before executing the transaction.
  
  
  Additional Information:
  
  This is a warning message (W_...), so it may allow you to continue after acknowledging it, but the system expects customer data for meaningful processing.
  Check the field help (F4) on the customer input field to select valid customers.
  If you are unsure about the customer numbers, consult your customer master data or your sales/finance department.
  In some custom reports or programs, this message might be triggered by validation logic that enforces customer input.
