  The SAP error message /SAPCND/CUSTOMIZING403 Entry is in SAP name space typically occurs when you are trying to create or modify a customizing entry in a namespace that is reserved for SAP. In SAP, namespaces are used to differentiate between SAP standard objects and customer-specific objects.

  Solution:
  
  Use Customer Namespace: Ensure that any custom entries you are creating or modifying use a customer namespace (typically starting with 'Z' or 'Y'). This means you should rename your entries to avoid using SAP's reserved names.
  Check Customizing Settings: Review the customizing settings you are trying to change. Make sure that they are intended for customer use and not for SAP standard configurations.
  Consult Documentation: Refer to SAP documentation or notes related to the specific customizing activity you are performing to ensure you are following the correct procedures.
