Specifically, this error occurs when a data object is bound to more than one type, which is not allowed. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause
  
  Multiple Bindings: The primary cause of this error is that a data object (like a field or variable) has been assigned to more than one data type. This can happen if the same data object is used in different contexts or if there are conflicting definitions in the data model.
  Incorrect Configuration: Misconfiguration in the data binding settings or the data model can lead to this error. This might occur during the design phase of forms or reports.
  Versioning Issues: If there are multiple versions of a form or data model, inconsistencies between them can lead to this error.
  
  Solution
  
  
  Check Data Bindings: Review the data bindings for the affected data object. Ensure that each data object is bound to only one type. You can do this by:
  
  Opening the form or data model in the FDT editor.
  Navigating to the data object in question and checking its properties.
  Ensuring that it is not bound to multiple types.
  
  
  
  Remove Conflicting Bindings: If you find that a data object is bound to multiple types, you will need to remove the conflicting bindings. This may involve:
  
  Deleting or modifying the incorrect bindings.
  Ensuring that the data object is only associated with the intended data type.
  
  
  
  Validate Data Model: After making changes, validate the entire data model to ensure that there are no other similar issues. This can help catch any additional errors before deployment.
  
  
  Test Changes: Once you have made the necessary adjustments, test the form or report to ensure that the error no longer occurs and that the data is being processed correctly.
