  SAP Error Message:
  W_CB188: List and customer exclude one another
  
  
  Cause:
  This warning message occurs in SAP when you try to assign both a customer and a customer list simultaneously in a context where these two are mutually exclusive. In other words, the system does not allow you to specify a single customer and a customer list at the same time because they represent overlapping or conflicting selection criteria.
  Typically, this happens in scenarios such as:
  
  Pricing condition records
  Customer-specific pricing or discounts
  Customer master data maintenance
  Customer group or list assignments in sales documents or master data
  
  The system expects either a single customer or a customer list (group of customers), but not both together.
  
  
  Solution:
  
  Choose either a single customer or a customer list, but not both at the same time.
  Review the data entry screen or configuration where the error occurs and remove either the customer or the customer list field.
