• What is the cause and solution for SAP error message REBDAO048 - There is already another object type (&1) on the same level ?

  The SAP error message REBDAO048 indicates that there is a conflict with object types at the same level in a project or structure. This typically occurs in the context of SAP Project System (PS) or SAP Real Estate Management (RE) when you are trying to create or modify an object (like a project, WBS element, or investment measure) that conflicts with an existing object of a different type at the same hierarchical level.
  Cause:
  The error is triggered when:
  
  You attempt to create or assign an object (e.g., a WBS element) at a level where another object of a different type already exists.
  For example, if you have a project and you try to add a WBS element at the same level where a network or another project already exists, this error will occur.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Objects: Review the structure of the project or hierarchy where you are trying to create the new object. Identify what object types are already present at that level.
  
  
  Change Object Type: If you need to create a new object, ensure that it is of the same type as the existing objects at that level. For instance, if there is already a project, you may need to create another project or a WBS element under that project.
  
  
  Reorganize Structure: If necessary, consider reorganizing your project structure. You may need to move existing objects to different levels or create new levels in the hierarchy to accommodate the new object.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on object types and their hierarchical relationships.
  
  
  Check Authorizations: Ensure that you have the necessary authorizations to create or modify objects in the project structure.
  
  
  Contact Support: If the issue persists and you cannot identify the conflicting object, consider reaching out to your SAP support team for further assistance.
