• What is the cause and solution for SAP error message DRD126 - &1 is not an external customer, but a plant with a customer master ?

  The SAP error message DRD126 indicates that the system is trying to process a plant that is not recognized as an external customer but rather as a plant with a customer master. This typically occurs in scenarios where there is a mismatch in the configuration or data setup related to customer and plant definitions.
  Cause:
  
  Incorrect Master Data Configuration: The plant in question may be set up incorrectly in the system. It might be defined as a customer in the customer master data but is not recognized as an external customer.
  Data Inconsistency: There may be inconsistencies in the data between the customer master and the plant data.
  Transaction Context: The transaction being executed may require a valid external customer, but the system is referencing a plant instead.
  
  Solution:
  
  
  Check Customer Master Data:
  
  Go to the customer master data (transaction code XD03 for general data or VD03 for sales area data) and verify that the customer is set up correctly.
  Ensure that the customer is marked as an external customer if it is supposed to be one.
  
  
  
  Review Plant Configuration:
  
  Check the plant configuration in the system (transaction code OX10 for plant settings) to ensure that it is correctly defined and linked to the appropriate customer master data.
  Ensure that the plant is not mistakenly set up as a customer.
  
  
  
  Data Consistency Check:
  
  Run data consistency checks to identify any discrepancies between the customer and plant data.
  Use transaction codes like SE16 to view the relevant tables (e.g., KNA1 for customer master, T001W for plant data) and verify the entries.
  
  
  
  Adjust Transaction Logic:
  
  If the transaction being executed is not intended to involve a plant, review the logic to ensure that it is correctly referencing the intended external customer.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to this error message for any specific guidance or patches that may address the issue.
