• What is the cause and solution for SAP error message GL347 - Both S and U exits are being used in field movement ?

  The SAP error message GL347 indicates that both S (substitution) and U (user exit) are being used in the field movement for a particular field in the General Ledger (GL) accounting process. This situation typically arises when there is a conflict in the way that data is being processed or modified during the posting of financial documents.
  Cause:
  
  
  Conflicting Logic: The error occurs when both substitution rules and user exits are trying to modify the same field in a conflicting manner. This can happen if:
  
  A substitution is defined for a field that is also being modified by a user exit.
  The logic in the user exit and the substitution is not aligned, leading to ambiguity in which value should be used.
  
  
  
  Configuration Issues: There may be configuration settings in the SAP system that allow both mechanisms to be applied to the same field, which is not permitted.
  
  
  Solution:
  
  
  Review Substitution and User Exit Logic:
  
  Check the substitution rules defined in transaction code OB28 (for substitution) to see if there are any rules that apply to the field in question.
  Review the user exits (often implemented in function modules) that are modifying the same field. You can find user exits related to GL postings in the SAP documentation or by checking the relevant function modules.
  
  
  
  Decide on One Approach:
  
  Choose either to use substitution or user exit for the field movement, but not both. This may involve:
  
  Modifying the user exit to remove the logic that conflicts with the substitution.
  Adjusting the substitution rules to ensure they do not apply when the user exit is active.
  
  
  
  
  
  Testing:
  
  After making changes, thoroughly test the posting process to ensure that the error is resolved and that the desired behavior is achieved.
  
  
  
  Documentation:
  
  Document any changes made to the configuration or code for future reference and to assist other team members.
