Smart SAP Assistant

• What is the cause and solution for SAP error message MDC_HDB_MTC014 - ABAP package &1 is in the SAP namespace; choose another package ?

  The SAP error message MDC_HDB_MTC014 indicates that you are trying to create or modify an ABAP package that is in the SAP namespace. In SAP, the namespace is divided into two main categories: the SAP namespace (which is reserved for SAP standard objects) and the customer namespace (which is available for customer-specific developments).
  Cause:
  The error occurs because:
  
  You are attempting to create or modify an ABAP package with a name that starts with "SAP" or is otherwise reserved for SAP's own development. Packages in the SAP namespace are not available for customer modifications or new developments.
  
  Solution:
  To resolve this error, you should:
  
  Choose a Different Package Name: Select a package name that is in the customer namespace. Customer namespaces typically start with a prefix that is assigned to your organization (e.g., "Z" or "Y"). 
  Check Existing Packages: Before creating a new package, check if there are existing packages in your customer namespace that you can use or extend.
  Use Transaction SE80: You can use transaction SE80 (Object Navigator) to create a new package. Make sure to specify a name that adheres to the naming conventions for customer packages.
  
  Related Information:
  
  Namespace Conventions: SAP reserves certain namespaces for its own use. Customer namespaces are typically prefixed with "Z" or "Y" to distinguish them from SAP's standard objects.
  Package Creation: When creating a package, ensure that you have the necessary authorizations and that you follow your organization's development guidelines.
  Transport Requests: If you are working in a development environment, remember that any changes or new packages will need to be included in transport requests for movement to other environments (e.g., QA, Production).
  
  If you continue to face issues or have specific requirements, consider consulting your SAP Basis or development team for further assistance.
