• What is the cause and solution for SAP error message NJIT_MSG108 - &1 Reference Types with SAP reserved namespaces are not processed ?

  The SAP error message NJIT_MSG108 indicates that there is an issue with reference types that are using SAP reserved namespaces. This typically occurs in the context of ABAP programming or when working with certain SAP development tools.
  Cause:
  The error arises when a reference type (such as a class, interface, or data type) is defined in a namespace that is reserved by SAP. SAP reserves certain namespaces (like SAP, SAP_, etc.) for its own development and system objects. If a custom object is created in one of these namespaces, it can lead to conflicts or issues during processing.
  Solution:
  To resolve this error, you should take the following steps:
  
  
  Check the Namespace: Verify the namespace of the reference type that is causing the error. Ensure that it does not fall under the reserved SAP namespaces.
  
  
  Change the Namespace: If the reference type is indeed in a reserved namespace, you will need to move it to a custom namespace. Custom namespaces typically start with a prefix that identifies your organization or project (e.g., Z* or Y*).
  
  
  Adjust Code References: After changing the namespace, make sure to update any code that references the old namespace to point to the new one.
  
  
  Transport Requests: If you are working in a development environment, ensure that any changes are included in the appropriate transport requests for deployment to other environments (like QA or Production).
  
  
  Check for Dependencies: If the reference type is used in multiple places, ensure that all dependencies are updated accordingly to avoid further issues.
  
  
  Related Information:
  
  SAP Namespaces: SAP reserves certain namespaces for its own use. Custom development should always be done in a namespace that is not reserved by SAP to avoid conflicts.
  ABAP Development Guidelines: Follow best practices for ABAP development, including naming conventions and namespace usage.
  SAP Notes: Check SAP Notes for any specific guidance or updates related to this error message. SAP frequently updates its documentation and may provide additional context or solutions.
