What causes this issue?

You want to assign usage object &V1& to an architectural object. However
the usage object has not yet been assigned uniquely to a higher-level
object within the assignment period.

System Response

The system does not allow you to save the changes.

How to fix this error?

Make one of the following changes:
A higher-level object has not been uniquely assigned within the
assignment period (&V2&). Correct the assignment period.
The assignment within the architectural hierarchy is not unique. You may
experience this, for example, if a pooled space is to be assigned to the
architectural view and the buildings for the pooled space have either
not been assigned to an architectural hierarchy or have been assigned to
a different one. First assign the higher-level object for the usage
object to the higher-level object for the architectural object that you
want to assign.
Undo the assignment in the architectural object, and process the periods
and hierarchies relating to the usage objects.

REBDCA008 - Details

• The SAP error message REBDCA008 indicates that there is an issue with the assignment of a higher-level object in the context of a cost object or a project. Specifically, it means that the higher-level object (e.g., a project or order) is not uniquely assigned to the lower-level object (e.g., a cost center or internal order). This can occur in various SAP modules, particularly in Controlling (CO) and Project System (PS).
  
  Cause:
  
  Duplicate Assignments: The higher-level object is assigned to multiple lower-level objects, leading to ambiguity in the assignment.
  
  Configuration Issues: There may be issues in the configuration of the cost object hierarchy or the assignment rules.
  Data Integrity Issues: There could be inconsistencies in the master data or transaction data that lead to this error.
  
  
  Solution:
  
  
  Check Assignments: Review the assignments of the higher-level object to ensure that it is uniquely assigned to the lower-level object. You can do this by navigating to the relevant transaction
