• What is the cause and solution for SAP error message COM_PRODUCT071 - Object type & has multiple subtypes ?

  The SAP error message COM_PRODUCT071 indicates that the object type you are trying to work with has multiple subtypes defined in the system. This typically occurs in the context of product master data management, particularly when dealing with product hierarchies or classifications.
  Cause:
  The error arises when:
  
  You are trying to create or modify a product that is associated with multiple subtypes, but the system expects a single subtype for the operation you are performing.
  There may be inconsistencies in the product data or configuration that lead to ambiguity regarding which subtype should be used.
  
  Solution:
  To resolve the COM_PRODUCT071 error, you can take the following steps:
  
  
  Check Product Configuration:
  
  Review the product master data to identify the subtypes associated with the object type in question. You can do this by navigating to the product master data in the relevant transaction (e.g., C223 for product master data).
  
  
  
  Identify Subtypes:
  
  Use transaction COM_PRODUCT or C223 to check the subtypes assigned to the product. Ensure that the product is correctly classified and that there are no conflicting entries.
  
  
  
  Select a Single Subtype:
  
  If the operation you are performing requires a single subtype, you may need to specify which subtype to use. This could involve modifying the product data to ensure that only one subtype is active or relevant for the operation.
  
  
  
  Data Consistency:
  
  Ensure that the data is consistent across all relevant tables and that there are no orphaned or incorrectly linked records. You may need to run consistency checks or data validation processes.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on handling product subtypes and classifications. This can provide insights into best practices and configuration settings.
