• What is the cause and solution for SAP error message FDT_EXPRESSIONS718 - Writing table lines requires change mode "insert" (position &1) ?

  The SAP error message FDT_EXPRESSIONS718 indicates that there is an issue with the mode in which you are trying to write to a table. Specifically, the error states that writing table lines requires the change mode to be set to "insert" at a specified position.
  Cause:
  This error typically occurs in the context of using the SAP Fiori or SAP GUI when you are trying to insert or modify data in a table but the system is not in the correct mode to allow for that operation. The error message suggests that the system expects an "insert" operation, but it may be in a different mode (like "update" or "read").
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Change Mode: Ensure that the operation you are trying to perform is indeed an "insert" operation. If you are trying to add new entries to a table, make sure that the system is set to the correct mode.
  
  
  Review Code Logic: If you are working with custom code (e.g., ABAP code), review the logic to ensure that the change mode is set correctly before attempting to write to the table. You may need to explicitly set the mode to "insert" using the appropriate function or method.
  
  
  Transaction Settings: If you are using a specific transaction or application, check the settings or configurations to ensure that they allow for insert operations. Sometimes, user authorizations or transaction settings can restrict certain operations.
  
  
  Debugging: If you have access to debugging tools, you can step through the code to see where the change mode is being set and identify why it is not in the expected state.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for the specific transaction or function module you are using. There may be additional requirements or settings that need to be configured.
  
  
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with SAP experts who can provide more specific guidance based on your system configuration.
