• What is the cause and solution for SAP error message 3T004 - Possible collision of proposal with existing substitution on & ?

  The SAP error message 3T004 indicates a potential collision between a new substitution proposal and an existing substitution rule in the system. This typically occurs in the context of SAP's substitution functionality, which is used to automatically replace certain values or fields based on predefined rules.
  Cause:
  The error arises when you attempt to create or modify a substitution proposal that conflicts with an existing substitution rule. This can happen if:
  
  The new substitution proposal overlaps with the criteria of an existing substitution.
  The same field or value is being targeted by multiple substitution rules, leading to ambiguity in which rule should be applied.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Existing Substitutions:
  
  Check the existing substitution rules in the system to identify any that may conflict with your new proposal. You can do this by navigating to the relevant transaction (e.g., transaction code OB28 for substitution rules).
  
  
  
  Modify or Delete Conflicting Rules:
  
  If you find a conflicting substitution rule, you may need to modify it to avoid the collision. This could involve changing the criteria or the fields being substituted.
  Alternatively, if the existing rule is no longer needed, consider deleting it.
  
  
  
  Adjust New Proposal:
  
  If modifying the existing rules is not feasible, you may need to adjust your new substitution proposal to ensure it does not conflict with existing rules.
  
  
  
  Testing:
  
  After making changes, test the substitution functionality to ensure that the desired behavior is achieved without any errors.
  
  
  
  Documentation:
  
  Document any changes made to the substitution rules for future reference and to maintain clarity in the system.
  
  
  
  Related Information:
