• What is the cause and solution for SAP error message DO893 - Key/Index &: Comp.&: Namespace in name & does not begin with 1st position ?

  The SAP error message DO893 indicates an issue related to the naming convention of a key or index in the database. Specifically, it suggests that the namespace in the name of the key or index does not begin with the expected character or position. This can occur in various scenarios, such as when creating or modifying database objects, especially in the context of ABAP Dictionary objects.
  Cause:
  
  Incorrect Naming Convention: The key or index name does not adhere to the required naming conventions set by SAP. For example, certain prefixes or characters may be expected at the beginning of the name.
  Namespace Issues: The namespace defined for the object may not be correctly set, or the object may be using a reserved namespace that is not allowed.
  Database Object Definition: When defining a key or index, the name may have been entered incorrectly, leading to this error.
  
  Solution:
  
  Check Naming Conventions: Ensure that the name of the key or index follows the SAP naming conventions. Typically, names should start with a letter and can include letters, numbers, and underscores.
  Review Namespace Settings: Verify that the namespace for the object is correctly defined. If you are using a custom namespace, ensure it is properly registered and follows the required format.
  Modify the Object Name: If the name is incorrect, modify it to comply with the naming standards. You can do this in the ABAP Dictionary (transaction SE11) or wherever the object is being defined.
  Consult Documentation: Refer to SAP documentation or guidelines regarding naming conventions for database objects to ensure compliance.
