• What is the cause and solution for SAP error message /PLMI/RFO_SP018 - More than one of item &1 of &2 &3 is marked as "Alternative Used" ?

  The SAP error message /PLMI/RFO_SP018 indicates that there is a conflict in the configuration of alternative items in a bill of materials (BOM) or a similar structure. Specifically, it means that more than one item has been marked as "Alternative Used" for a particular item in the context of a specific configuration or production order.
  Cause:
  
  Multiple Alternatives: The system has detected that multiple items are marked as alternatives for the same base item, which is not allowed. This can happen if the configuration of the BOM or the item master data has not been set up correctly.
  Data Entry Error: During the creation or modification of the BOM or item master, multiple alternatives may have been incorrectly flagged.
  Configuration Issues: There may be issues with how the alternatives are defined in the system, leading to ambiguity in which alternative should be used.
  
  Solution:
  
  
  Review BOM/Item Configuration:
  
  Go to the BOM or item master data where the error is occurring.
  Check the list of alternative items and ensure that only one item is marked as "Alternative Used" for the specific base item.
  If multiple items are marked, decide which one should be the primary alternative and adjust the settings accordingly.
  
  
  
  Adjust Alternative Settings:
  
  If you need to keep multiple alternatives, consider using a different configuration approach, such as using a different BOM or item category that allows for multiple alternatives without conflict.
  
  
  
  Data Consistency Check:
  
  Run a consistency check on the BOM or item master data to identify any other potential issues that may be causing the error.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for guidance on how to properly configure alternatives in your specific version of SAP.
