• What is the cause and solution for SAP error message WX151 - Plant or customer & already exists ?

  The SAP error message WX151: "Plant or customer & already exists" typically occurs in the context of customer master data maintenance or plant master data assignment. Here's a detailed explanation:
  
  Cause:
  
  The error message WX151 indicates that the combination of Plant and Customer you are trying to create or assign already exists in the system.
  This usually happens when you attempt to create a new customer master record or assign a plant to a customer, but the system finds that the same plant-customer combination is already present.
  It can also occur during data upload or batch input sessions where duplicate entries are being created.
  
  
  When does it occur?
  
  While creating or changing customer master data (transaction codes like XD01, VD01, FD01).
  During assignment of a plant to a customer in sales area data.
  During data migration or batch input sessions.
  When maintaining customer-plant relationships in sales or logistics modules.
  
  
  Solution:
  
  
  Check Existing Data:
  
  Use transaction XD03 (Display Customer) or VD03 to check if the customer already exists with the plant in question.
  Verify if the plant is already assigned to the customer in the sales area data.
  
  
  
  Avoid Duplicate Entries:
  
  If the customer-plant combination already exists, do not create a new one.
  Instead, change or update the existing record if needed.
  
  
  
  Correct Data Upload Files:
  
  If the error occurs during data migration, check the source data for duplicates.
  Remove or correct duplicate entries before uploading.
  
  
  
  Use SAP Reports or Tables:
  
  Check table KNVP (Customer Master Partner Functions) or KNVV (Customer Master Sales Data) for existing plant-customer assignments.
  Use SE16/SE16N to query these tables with the customer and plant combination.
