• What is the cause and solution for SAP error message MDG_BS_BP_MLT_AS006 - Customer &1 is already assigned to business partner &2 ?

  The SAP error message MDG_BS_BP_MLT_AS006 indicates that a customer (or business partner) is already assigned to another business partner in the system. This typically occurs in the context of Master Data Governance (MDG) for Business Partners when there is an attempt to create or modify a business partner that conflicts with existing assignments.
  Cause:
  
  Duplicate Assignment: The customer you are trying to assign is already linked to a different business partner. This can happen if the same customer number is being used for multiple business partners.
  Data Migration Issues: During data migration or integration processes, if the same customer data is being imported multiple times, it can lead to conflicts.
  Incorrect Configuration: There may be configuration settings in the MDG or Business Partner setup that are not allowing the assignment due to existing relationships.
  
  Solution:
  
  
  Check Existing Assignments: 
  
  Use transaction codes like BP (Business Partner) to check the existing assignments of the customer and the business partner in question.
  Verify if the customer is indeed assigned to another business partner.
  
  
  
  Modify or Remove Existing Assignment:
  
  If the customer is assigned to another business partner and you want to change this, you may need to remove the existing assignment first before reassigning it to the desired business partner.
  Ensure that you have the necessary authorizations to make these changes.
  
  
  
  Data Cleansing:
  
  If this error arises from data migration, ensure that the data being imported does not contain duplicates or conflicts.
  Cleanse the data to ensure that each customer is uniquely assigned to a single business partner.
