  The SAP error message COM_PRODUCT_CUST008 indicates that there is an issue with the assignment of numbers to products in the system. Specifically, it states that numbers cannot be assigned externally for a particular product type and category. This typically occurs in the context of product master data management within SAP's Advanced Planning and Optimization (APO) or similar modules.
  Cause:
  The error is usually caused by one of the following reasons:
  
  
  Configuration Settings: The product type or category is configured in such a way that it does not allow external number assignment. This is often a setting in the product master data configuration.
  
  
  Number Assignment Settings: The system may be set to use internal number assignment for certain product types or categories, which means that users cannot manually assign numbers to these products.
  
  
  Authorization Issues: There may be restrictions based on user roles or authorizations that prevent the assignment of numbers.
  
  
  Data Integrity Issues: There may be inconsistencies or missing data in the product master data that prevent the assignment of numbers.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Configuration:

  Verify if the product type/category is set to allow external number assignment. If not, you may need to change the configuration to allow it.
  
  
  
  Use Internal Number Assignment:
  
  If external number assignment is not allowed, consider using the internal number assignment method. This means letting the system generate the product numbers automatically.
  
  
  
  Review User Authorizations:
  
  Ensure that the user attempting to assign the number has the necessary authorizations to do so. Check the roles and permissions assigned to the user.
  
  
  
  Data Validation:
