• What is the cause and solution for SAP error message TN_PROCESS302 - Line &1: Only the operations 'D' and 'I' are allowed ?

  The SAP error message TN_PROCESS302 indicates that there is an issue with the processing of a transaction in the SAP system, specifically related to the operations being performed. The message states: "Only the operations 'D' and 'I' are allowed," which means that the system is expecting either a 'Delete' (D) or 'Insert' (I) operation, but it has encountered an operation that is not permitted.
  Cause:
  
  
  Invalid Operation: The error typically occurs when an operation other than 'D' (Delete) or 'I' (Insert) is attempted. This could be due to:
  
  An attempt to update (U) or modify an existing record when only insertions or deletions are allowed.
  A misconfiguration in the data processing logic or a program that is trying to perform an unsupported operation.
  
  
  
  Data Integrity Issues: The data being processed may not meet the criteria for the allowed operations, leading to the system rejecting the operation.
  
  
  Custom Code or Enhancements: If there are custom developments or enhancements in the system, they might be incorrectly handling the operations.
  
  
  Solution:
  
  
  Check the Operation Type: Review the code or transaction that is generating the error. Ensure that only 'D' or 'I' operations are being executed. If an update operation is necessary, you may need to adjust the logic to handle it appropriately.
  
  
  Review Data Processing Logic: If you are using a custom program or enhancement, check the logic to ensure it adheres to the expected operations. Modify the code to ensure that it only attempts to insert or delete records.
  
  
  Debugging: If you have access to debugging tools, you can set breakpoints in the relevant code to see what operations are being attempted and why the error is being triggered.
  
  
  Consult Documentation: Review the SAP documentation or help resources related to the specific transaction or module you are working with to understand the expected operations.
  
  
  Testing: After making changes, test the transaction or program thoroughly to ensure that it behaves as expected and that the error does not recur.
