• What is the cause and solution for SAP error message CM_EHFND_BO_SUB003 - It is not allowed to change the internal number. ?

  The SAP error message CM_EHFND_BO_SUB003 with the description "It is not allowed to change the internal number" typically occurs in the context of Business Object (BO) operations, particularly when dealing with entities that have an internal identifier that should not be modified.
  Cause:
  This error usually arises when:
  
  Attempting to Modify Internal Key: You are trying to change the internal number (or key) of a business object that is meant to be immutable. In many cases, internal keys are generated by the system and are not intended to be altered by users or through API calls.
  Incorrect Data Handling: The data being sent to the system may include an internal number that is not allowed to be changed, possibly due to a misunderstanding of the data model or API usage.
  Business Logic Restrictions: The business logic defined in the application may enforce that certain fields, especially internal identifiers, remain unchanged after creation.
  
  Solution:
  To resolve this error, consider the following steps:
  
  Review the Data Model: Ensure that you are not attempting to modify the internal number of a business object. Check the documentation for the specific business object to understand which fields are mutable and which are not.
  Correct API Usage: If you are using an API to create or update business objects, ensure that you are following the correct procedures. For instance, when creating a new object, do not include the internal number in the request payload.
  Check for Updates: If you need to update an object, ensure you are only modifying fields that are allowed to be changed. The internal number should not be part of the update request.
  Consult Documentation: Refer to the SAP documentation or the specific API documentation for the business object you are working with to understand the constraints and requirements.
  Error Handling: Implement error handling in your application to catch this specific error and provide a user-friendly message or log it for further investigation.
