• What is the cause and solution for SAP error message MDC_BP_MODEL053 - Number range for customers must not be internal. ?

  The SAP error message MDC_BP_MODEL053, which states "Number range for customers must not be internal," typically occurs when there is an issue with the configuration of number ranges for business partners (BPs) in the SAP system. This error is related to the way number ranges are defined for customer master records in the Business Partner (BP) model.
  Cause:
  The error arises when the system is configured to use an internal number range for customer business partners, which is not allowed in certain scenarios. Internal number ranges are automatically generated by the system, while external number ranges require manual entry. In the context of business partners, SAP expects that customer records should use external number ranges to ensure proper management and tracking.
  Solution:
  To resolve this error, you need to check and adjust the number range settings for the customer business partners. Here are the steps to do this:
  
  
  Access the Number Range Configuration:
  
  Go to the SAP Easy Access screen.
  Navigate to the following path: SPRO -> SAP Reference IMG -> Cross-Application Components -> Master Data Synchronization -> Business Partner -> Define Number Ranges for Business Partners.
  
  
  
  Check the Number Range Settings:
  
  Look for the number range interval assigned to the customer business partners.
  Ensure that the number range is set to "External" rather than "Internal." 
  
  
  
  Adjust the Number Range:
  
  If the number range is set to internal, you will need to create a new number range interval that is external.
  Define the new number range and assign it to the relevant business partner role (e.g., customer).
  
  
  
  Assign the Number Range:
  
  Make sure that the new external number range is assigned to the customer role in the business partner settings.
  
  
  
  Test the Configuration:
  
  After making the changes, try to create or modify a customer business partner again to see if the error persists.
  
  
  
  Related Information:
  
  Business Partner Roles: Understand the different roles that business partners can have (e.g., customer, vendor) and how number ranges are assigned to these roles.
  Number Range Management: Familiarize yourself with how number ranges work in SAP, including the difference between internal and external number ranges.
  SAP Notes and Documentation: Check SAP Notes for any specific patches or updates related to this error message, as well as the official SAP documentation for best practices in managing business partner data.
