• What is the cause and solution for SAP error message ATP_ABC_LOGIC002 - ABC inline substitution cannot be executed: there is a supply assignment. ?

  The SAP error message ATP_ABC_LOGIC002 indicates that there is an issue with the Availability Check (ATP - Available to Promise) logic, specifically related to inline substitution. This error typically arises when the system is unable to execute the inline substitution due to existing supply assignments.
  Cause:
  
  Supply Assignment Exists: The error occurs when there is a supply assignment for the material in question, which prevents the ATP logic from executing the inline substitution.
  Configuration Issues: There may be configuration settings in the ATP check that are not aligned with the current supply chain setup.
  Material Master Data: The material master data may not be correctly set up, leading to conflicts in the ATP logic.
  Custom Logic: If there are custom enhancements or modifications in the ATP logic, they may interfere with the standard processing.
  
  Solution:
  
  Review Supply Assignments: Check the supply assignments for the material in question. If there are existing assignments that are not needed, consider removing or adjusting them.
  Check ATP Configuration: Review the configuration settings for the ATP check in the system. Ensure that the settings are appropriate for the business process and that inline substitution is allowed.
  Material Master Review: Verify the material master data for the affected material. Ensure that all relevant fields are correctly populated and that there are no inconsistencies.
  Debugging: If the issue persists, consider debugging the ATP logic to identify where the inline substitution is failing. This may require technical expertise.
  Consult Documentation: Refer to SAP documentation or notes related to ATP and inline substitution for any specific guidance or known issues.
  SAP Support: If the problem cannot be resolved internally, consider reaching out to SAP support for assistance. Provide them with the error message details and any relevant configuration settings.
  
  Related Information:
