Smart SAP Assistant

• What is the cause and solution for SAP error message /SAPAPO/PSTRU028 - All location products are assigned to model &1 ?

  The SAP error message /SAPAPO/PSTRU028 indicates that all location products are assigned to a specific model in the Advanced Planning and Optimization (APO) module of SAP. This message typically arises during planning or modeling activities when the system detects that the products at a location are already linked to a particular planning model, which may not be the intended configuration for your planning scenario.
  Cause:
  
  Model Assignment: All products at the specified location are already assigned to a planning model, which may restrict further actions like creating new models or modifying existing ones.
  Planning Area Configuration: The planning area may be configured in such a way that it does not allow for multiple models for the same location products.
  Data Integrity: There may be data integrity issues where the system is unable to recognize the intended model assignment due to inconsistencies in the master data.
  
  Solution:
  
  Review Model Assignments: Check the model assignments for the location products. You can do this by navigating to the relevant planning area and reviewing the model configuration.
  Change Model Assignment: If you need to assign a different model, you may need to unassign the current model from the products at that location. This can typically be done in the model management transaction (e.g., /SAPAPO/MC62).
  Create a New Model: If the intention is to create a new model, ensure that the existing model is not preventing this. You may need to create a new planning area or modify the existing one to accommodate the new model.
  Check Configuration: Ensure that the planning area and model configurations are set up correctly to allow for the desired planning scenarios.
  Consult Documentation: Refer to SAP documentation or help resources for specific instructions on managing models and planning areas in APO.
  
  Related Information:

  User Roles and Authorizations: Ensure that you have the necessary authorizations to make changes to model assignments and planning areas.
  Testing in a Sandbox: If possible, replicate the issue in a sandbox environment to test potential solutions without affecting production data.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP Basis or APO support team for further assistance.
