• What is the cause and solution for SAP error message O1819 - Customer master record '&' contains vendor number '&' ?

  The SAP error message O1819 indicates that there is a conflict in the customer master record where a customer is also assigned a vendor number. This situation typically arises when a business partner is set up in both roles (customer and vendor) but is not configured correctly in the system.
  Cause:
  
  Dual Role Assignment: The customer master record is linked to a vendor number, which is not allowed in certain configurations or scenarios.
  Data Entry Error: During the creation or modification of the customer master record, the vendor number may have been incorrectly entered or assigned.
  Configuration Issues: The system may not be set up to handle business partners that serve dual roles properly.
  
  Solution:
  
  
  Check the Customer Master Record:
  
  Go to the customer master record in transaction code XD03 (Display Customer) or XD02 (Change Customer).
  Verify if the vendor number is indeed assigned to the customer record.
  
  
  
  Remove the Vendor Assignment:
  
  If the customer should not have a vendor number, you can remove the vendor assignment from the customer master record.
  Use transaction code XD02 to change the customer record and remove the vendor number.
  
  
  
  Create Separate Records:
  
  If the business partner needs to exist as both a customer and a vendor, ensure that they are set up as separate records in the system.
  Use transaction codes XK01 (Create Vendor) and XD01 (Create Customer) to create distinct records.
  
  
  
  Check Configuration:
  
  Review the configuration settings in the SAP system to ensure that it allows for dual-role business partners if that is the intended setup.
  This may involve checking the settings in the SPRO transaction under the relevant sections for customer and vendor management.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidelines on managing business partners in dual roles.
  
  
  
  Related Information:
  
  Business Partner Concept: In newer versions of SAP (like S/4HANA), the Business Partner (BP) concept is used, which allows a single entity to be defined as both a customer and a vendor. Ensure that you are familiar with how to manage business partners in your version of SAP.
  Transaction Codes:
  
  XD01: Create Customer
  XD02: Change Customer
  XD03: Display Customer
  XK01: Create Vendor
  XK02: Change Vendor
