  Namespace Management: If you are working in a custom namespace, ensure that your naming conventions are consistent and do not overlap with standard SAP namespaces.
  Review Code References: If the sub-module is being referenced in code, ensure that all references are updated to reflect the new name if you decide to rename it.
