• What is the cause and solution for SAP error message W+579 - Inclusion of ref. customers in transfer only possible for message type &1 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  W+579 Inclusion of ref. customers in transfer only possible for message type &1
  
  Cause:
  This warning message occurs during the processing of customer master data or customer-related data transfer (e.g., in ALE/IDoc processing or customer master data distribution). It indicates that the inclusion of reference customers (i.e., customers referenced or linked to the main customer) in the data transfer is only allowed for a specific message type.
  In other words, the system is trying to include reference customer data in a transfer or distribution process, but the current message type being used does not support this inclusion. The message type parameter &1 specifies the allowed message type for such inclusion.
  
  Explanation:
  
  Reference customers are customers linked to a main customer, often used in scenarios like partner functions or hierarchical customer relationships.
  When distributing or transferring customer data (e.g., via ALE/IDocs), certain message types are designed to handle reference customer data.
  If you attempt to include reference customers in a message type that does not support it, SAP raises this warning to prevent inconsistent or incomplete data transfer.
  
  
  Solution:
  
  Check the message type used for the customer data transfer or distribution.
  Use the correct message type that supports the inclusion of reference customers. The message type is indicated in the message text (&1).
  If you are configuring ALE or IDoc distribution, ensure that the partner profile and distribution model use the appropriate message type for customer master data that includes reference customers.
  Review the customizing settings in:
  
  Transaction WE20 (Partner Profiles)
  Transaction BD64 (Distribution Model)
  Transaction WE21 (Port Definition)
  
  
  If necessary, adjust the process to exclude reference customers when using message types that do not support them.
  
  
  Related Information:
  
  Message Class: W+5xx (Customer Master Data / ALE)
  Transactions: WE20, BD64, WE21, XD01/XD02 (Customer Master Data)
  ALE/IDoc: Customer master data distribution often uses message types like DEBMAS (Customer Master).
  SAP Notes: Check for SAP Notes related to ALE distribution of customer master data for any known issues or updates.
  Documentation: SAP Help Portal on ALE and IDoc processing for customer master data.
  
  
  Summary:
  
  The warning indicates a mismatch between the message type and the inclusion of reference customers.
  Use the correct message type that supports reference customers for data transfer.
  Adjust ALE/IDoc configuration accordingly.
