• What is the cause and solution for SAP error message FDT_CORE289 - Customer applications should be created in customer namespace ?

  The SAP error message FDT_CORE289 indicates that a customer application is being created in a namespace that is not designated for customer developments. In SAP, namespaces are used to differentiate between standard SAP objects and customer-specific objects. The standard SAP objects are typically in the SAP namespace, while customer-specific developments should be in a designated customer namespace (usually starting with a "Z" or "Y").
  Cause:
  The error occurs when:
  
  A developer attempts to create or modify an application in the SAP namespace instead of the customer namespace.
  The system is configured to enforce the rule that customer applications must reside in a customer namespace to avoid conflicts with standard SAP objects.
  
  Solution:
  To resolve this error, you should:
  
  Check the Namespace: Ensure that you are using the correct customer namespace for your application. The namespace should start with "Z" or "Y".
  Create a New Application: If you are trying to create a new application, make sure to specify the customer namespace when creating it.
  Modify Existing Applications: If you have an existing application in the SAP namespace, you may need to create a copy of it in the customer namespace and make your modifications there.
  Consult Documentation: Review SAP documentation or guidelines regarding the use of namespaces to ensure compliance with best practices.
  
  Related Information:
  
  Namespace Management: SAP provides tools and guidelines for managing namespaces. Familiarize yourself with these to avoid similar issues in the future.
  Transport Requests: When working with customer namespaces, ensure that your transport requests are correctly configured to include the objects in the customer namespace.
