This error indicates that a specific field that is expected to be present in the channel structure cannot be found.
  Causes:
  
  Field Not Available: The field specified in the error message (&1) is not present in the data source or the structure of the InfoProvider.
  Changes in Data Source: If there have been recent changes to the data source (like a change in the underlying database or a modification in the data model), the field may have been removed or renamed.
  Incorrect Mapping: There may be an issue with the mapping of fields in the transformation or data flow, leading to the system not being able to locate the field.

  Check for Transport Issues: If the issue arose after a transport, ensure that all relevant objects were transported correctly and that there are no missing dependencies.
  Debugging: If the issue persists, consider debugging the data flow to identify where the field is being referenced and why it cannot be found.
