  SAP Error Message:
  WSUBST006 - Error calling function module &1
  
  Cause:
  The error message WSUBST006 occurs when there is a problem during the call of a function module in SAPscript or Smart Forms processing. The placeholder &1 is replaced by the actual function module name that failed.
  Common causes include:
  
  The function module specified does not exist or is not active.
  The function module is not released for remote calls (RFC).
  Authorization issues preventing the function module from being executed.
  Incorrect parameters passed to the function module.
  System or communication errors if the function module is called remotely.
  Missing or incorrect configuration related to the function module.
  Runtime errors inside the function module itself.
  
  
  Solution:
  To resolve the WSUBST006 error, follow these steps:
  
  
  Identify the Function Module:
  
  Check the exact function module name in the error message (replaces &1).
  Use transaction SE37 to test the function module directly.
  
  
  
  Check Function Module Status:
  
  Ensure the function module exists and is active.
  Verify that it is released for remote calls if called remotely.
  
  
  
  Check Parameters:
  
  Review the parameters passed to the function module in the SAPscript or Smart Form.
  Make sure all required parameters are correctly filled and of the correct type.
  
  
  
  Authorization:
  
  Verify that the user executing the function module has the necessary authorizations.
  Use SU53 to check for authorization failures.
  
  
  
  Debugging:
  
  Debug the function module call to identify any runtime errors.
  Use breakpoints in SE37 or in the print program to trace the error.
  
  
  
  Check System Logs:
  
  Look into system logs (SM21) or short dumps (ST22) for related errors.
  
  
  
  Check Communication:

  Ensure that the print program and form are correctly linked and that the function module is designed to be called in this context.
  
  
  
  Example Scenario:
  
  A Smart Form calls a function module to fetch data.
  If the function module is deleted or changed without updating the form, WSUBST006 may occur.
