• What is the cause and solution for SAP error message W_CB386 - Copy function doesn't support that new condition deletes source condition ?

  SAP Error Message:
  
  W_CB386 Copy function doesn't support that new condition deletes source condition
  
  Cause
  This warning message occurs in SAP Pricing (Condition Technique) when you try to copy condition records using a copy function (e.g., in transaction VK11/VK12 or through programmatic means), and the new condition record you are attempting to create or update would effectively delete the source condition record.
  In other words, the system detects that the copy operation would result in the source condition being removed or invalidated, which is not supported by the copy function. This typically happens if:
  
  The new condition record has no valid data (e.g., all condition values are zero or blank), which is interpreted as a deletion.
  The copy function is used in a way that tries to overwrite the source condition with an empty or invalid condition.
  The copy logic or program incorrectly attempts to delete the source condition instead of creating a new one.
  
  
  Explanation
  
  Condition Records in SAP pricing are stored with keys and validity periods.
  Copy functions are designed to create new condition records based on existing ones.
  Deleting a condition record is a separate operation and cannot be done via the copy function.
  If the new condition record is empty or invalid, SAP interprets this as a deletion attempt, which is not allowed in the copy process.
  
  
  Solution
  
  
  Check the Data Being Copied:
  
  Ensure that the new condition record you want to create has valid data (e.g., non-zero condition values).
  Avoid copying condition records that would result in empty or zero-value conditions unless you intend to delete them explicitly.
  
  
  
  Use Correct Transaction/Method for Deletion:
  
  If your intention is to delete a condition record, use the appropriate transaction (e.g., VK12 to delete condition records) or programmatic deletion methods.
  Do not use the copy function to delete condition records.
  
  
  
  Review Copy Logic:
  
  If you are using a custom program or user exit/BAdI to copy condition records, review the logic to ensure it does not attempt to create empty or invalid condition records.
  Add validation to prevent copying when the target condition would be empty or invalid.
  
  
  
  Check Validity Periods:
  
  Make sure the validity periods of the new condition record do not overlap or conflict with the source condition in a way that would cause deletion.
