• What is the cause and solution for SAP error message C1804 - Display mode - value cannot be selected ?

  The SAP error message C1804, which states "Display mode - value cannot be selected," typically occurs in the context of SAP applications when a user attempts to select a value in a display mode that is not allowed. This can happen in various scenarios, such as when working with reports, transactions, or data entry screens.
  Causes:
  
  Display Mode Restrictions: The field you are trying to select a value for may be in a display-only mode, meaning it is not editable or selectable.
  Authorization Issues: The user may not have the necessary authorizations to change or select values in that particular field.
  Field Configuration: The field may be configured in such a way that it does not allow selection in certain contexts (e.g., based on user roles or transaction types).

  Consult Configuration: If you have access to configuration settings, check if the field settings allow for selection in the current context. This may involve looking at the screen layout or field attributes in the relevant transaction.
  Use Alternative Transactions: If the current transaction does not allow for the selection, consider using an alternative transaction that provides the necessary functionality.
