• What is the cause and solution for SAP error message UJD_EXCEPTION056 - Number of '?' markers in external (&1) and internal (&2) must be equal ?

  The SAP error message UJD_EXCEPTION056 indicates a mismatch between the number of placeholders (or markers) in an external data source and the corresponding internal representation in the SAP system. This typically occurs in scenarios involving data extraction, transformation, or reporting where parameters are passed between different systems or components.
  Cause:
  The error arises when the number of placeholders (represented by '?') in the external data source (like a database query or a data source file) does not match the number of placeholders expected in the internal processing logic of SAP. This can happen due to:
  
  Mismatched Query Parameters: If a query is constructed with a certain number of parameters but the actual data source or the internal logic expects a different number.
  Changes in Data Structure: If the structure of the data source has changed (e.g., columns added or removed) but the corresponding SAP logic has not been updated.
  Incorrect Configuration: Misconfiguration in the data source settings or in the way the data is being fetched or processed.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the Query: Review the external query or data source to ensure that the number of placeholders matches the expected number in the SAP internal logic. Make sure that all required parameters are included.
  
  
  Update Data Source: If there have been changes to the data structure, update the SAP configuration or logic to reflect these changes. This may involve modifying the query or the data extraction logic.
  
  
  Parameter Mapping: Ensure that the parameters being passed from the external source to the internal processing are correctly mapped and that their counts match.
  
  
  Debugging: If the issue persists, consider enabling debugging or logging to trace the exact point of failure. This can provide insights into where the mismatch is occurring.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance related to the data source or module you are working with.
  
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide patches or updates that could resolve the issue.
