• What is the cause and solution for SAP error message /SAPAPO/ATP093 - User-defined substitution selection results in more than one substitution ?

  The SAP error message /SAPAPO/ATP093 indicates that a user-defined substitution selection has resulted in more than one substitution being found for a given product or material. This typically occurs in the context of Advanced Planning and Optimization (APO) when the system is trying to determine how to fulfill a demand but encounters multiple potential substitutions that meet the criteria.
  Cause:
  
  Multiple Substitutions Defined: There are multiple substitution materials defined for the same product in the system, and the selection criteria do not narrow it down to a single substitution.
  Configuration Issues: The configuration of the substitution logic may not be set up correctly, leading to ambiguous results.
  Data Integrity Issues: There may be inconsistencies or errors in the master data related to the products and their substitutions.
  
  Solution:
  
  
  Review Substitution Settings:
  
  Go to the material master data and check the substitution settings for the affected product. Ensure that the substitution logic is correctly defined.
  If multiple substitutions are valid, consider whether the selection criteria can be refined to ensure only one substitution is selected.
  
  
  
  Adjust Selection Criteria:
  
  Modify the user-defined selection criteria to ensure that it can uniquely identify a single substitution. This may involve changing the priority or conditions under which substitutions are considered.
  
  
  
  Data Cleanup:
  
  Check for any duplicate or unnecessary substitution entries in the system. Remove or consolidate them as needed to avoid confusion.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to substitution logic in APO to ensure that the setup aligns with best practices.
  
  
  
  Testing:
  
  After making changes, conduct tests to ensure that the error no longer occurs and that the system behaves as expected when substitutions are required.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SAPAPO/SDP94 (for demand planning) or /SAPAPO/ATP (for available-to-promise checks) to analyze the situation further.
  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide additional guidance on handling substitutions in APO.
  User Exits and BAdIs: If custom logic is being used for substitutions, review any user exits or Business Add-Ins (BAdIs) that may be influencing the substitution selection process.
  
  By following these steps, you should be able to resolve the error and ensure that your substitution logic works as intended.
