• What is the cause and solution for SAP error message /SAPAPO/DMMOD059 - Hierarchy &1 has already been assigned to model &2 ?

  The SAP error message /SAPAPO/DMMOD059 indicates that a specific hierarchy (denoted as &1) has already been assigned to a particular model (denoted as &2). This error typically occurs in the context of SAP Advanced Planning and Optimization (APO) when you are trying to assign a hierarchy to a model that is already linked to another model.
  Cause:
  
  Duplicate Assignment: The hierarchy you are trying to assign is already associated with another model. In SAP APO, each hierarchy can only be assigned to one model at a time.
  Configuration Error: There may be a misunderstanding in the configuration or setup of the models and hierarchies, leading to attempts to assign the same hierarchy to multiple models.
  
  Solution:
  
  
  Check Existing Assignments: 
  
  Go to the relevant transaction in SAP APO (e.g., /SAPAPO/HIERARCHY or similar) to check which model the hierarchy is currently assigned to.
  If you need to use the hierarchy for a different model, you will need to first remove it from the current model.
  
  
  
  Remove Assignment:
  
  If you determine that the hierarchy should be reassigned, you can remove it from the current model. This can typically be done in the hierarchy maintenance transaction.
  After removing the hierarchy from the existing model, you can then assign it to the desired model.
  
  
  
  Create a New Hierarchy:
  
  If the hierarchy needs to be used in multiple models simultaneously, consider creating a new hierarchy that is similar to the existing one, rather than trying to reassign the existing hierarchy.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help resources for specific steps on managing hierarchies and models in your version of SAP APO.

  User Authorization: Ensure that you have the necessary authorizations to make changes to hierarchies and models in SAP APO.
  
  By following these steps, you should be able to resolve the error and manage your hierarchies and models effectively in SAP APO.
