• What is the cause and solution for SAP error message /SAPAPO/PP_OPTIMIZER228 - No setup matrix assigned to resource &1 ?

  The SAP error message /SAPAPO/PP_OPTIMIZER228 No setup matrix assigned to resource &1 typically occurs in the context of SAP Advanced Planning and Optimization (APO) when the system is trying to perform a planning operation (like production planning or scheduling) and cannot find a setup matrix assigned to a specific resource.
  Cause:
  
  
  Missing Setup Matrix: The primary cause of this error is that the resource specified (denoted by &1 in the error message) does not have a setup matrix assigned to it. A setup matrix is essential for defining the setup times and costs associated with changing from one production order to another on the same resource.
  
  
  Configuration Issues: There may be configuration issues in the APO system where the setup matrix has not been properly defined or linked to the resource.
  
  
  Resource Definition: The resource may not be fully defined in the system, or it may not be set up to use a setup matrix.
  
  
  Solution:
  
  
  Assign a Setup Matrix:
  
  Go to the transaction code /SAPAPO/RESOURC (or the relevant transaction for resource maintenance).
  Locate the resource that is causing the error.
  Check the settings for the resource and ensure that a setup matrix is assigned. If not, create or assign an appropriate setup matrix.
  
  
  
  Create a Setup Matrix:
  
  If a setup matrix does not exist, you may need to create one. This can typically be done in the transaction code /SAPAPO/SETUP or through the relevant configuration menu.
  Define the necessary setup times and costs for the transitions between different production orders.
  
  
  
  Check Resource Configuration:
  
  Ensure that the resource is correctly configured to utilize the setup matrix. This includes checking the resource type and ensuring it is set up for production planning.
  
  
  
  Validate Data:
  
  After making changes, validate the data to ensure that the setup matrix is correctly linked and that the resource can now be used in planning.
  
  
  
  Testing:
  
  After assigning the setup matrix, perform a test run of the planning operation to ensure that the error does not reoccur.
  
  
  
  Related Information:
