• What is the cause and solution for SAP error message KB300 - Additional field can not be displayed ?

  The SAP error message "KB300 Additional field cannot be displayed" typically occurs in the context of SAP's reporting or data entry processes, particularly when dealing with additional fields in a transaction or report that are not configured correctly or are not available in the current context.
  Cause:
  
  Field Configuration: The additional field may not be configured in the relevant data structure or screen layout. This can happen if the field is not included in the data dictionary or if it is not activated for the specific transaction or report.
  Authorization Issues: The user may not have the necessary authorizations to view or access the additional field.
  Data Context: The additional field may not be relevant for the current data context or transaction, leading to its unavailability.
  Technical Issues: There could be underlying technical issues, such as missing updates or patches in the SAP system.

  Context Verification:
  
  Ensure that the additional field is relevant for the current transaction or report. If it is not applicable, consider whether it should be displayed or if the transaction should be modified to accommodate it.
