• What is the cause and solution for SAP error message /SAPAPO/DMRES145 - The resource is already being used in models; rates cannot be changed ?

  The SAP error message /SAPAPO/DMRES145 indicates that a resource is currently being utilized in one or more models, and therefore, its rates cannot be modified. This is a common issue in SAP Advanced Planning and Optimization (APO) when trying to change the rates of a resource that is actively linked to planning models.
  Cause:
  
  Resource Utilization: The resource you are trying to modify is already assigned to one or more planning models (e.g., production models, planning scenarios).
  Active Planning Models: If the resource is part of an active planning model, any changes to its rates will be restricted to maintain data integrity.
  Locked Data: The resource may be locked due to ongoing planning activities or transactions that are currently using it.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Active Models:
  
  Check which planning models are currently using the resource. You can do this by navigating to the relevant planning area or model in SAP APO and reviewing the resource assignments.
  
  
  
  Deactivate or Modify Models:
  
  If possible, deactivate the planning models that are using the resource. This will allow you to change the rates.
  Alternatively, if you need to keep the models active, consider creating a copy of the resource with the desired rates and assigning it to the models instead.
  
  
  
  Check for Locks:
  
  Ensure that there are no locks on the resource. You can use transaction codes like SM12 to check for locks and release them if necessary.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation or help files related to resource management in APO for any specific guidelines or restrictions regarding rate changes.
