  SAP Error Message:
  WXP774 Unexpected return code &1 for FB 'EVAL_FORMULA'
  
  Cause:
  This error occurs during the execution of a Web Dynpro application or a Business Server Page (BSP) when the function module (FB) EVAL_FORMULA returns an unexpected return code. The function module EVAL_FORMULA is used to evaluate formulas dynamically in SAP, often in the context of Web Dynpro applications or other dynamic evaluations.
  The unexpected return code indicates that the formula evaluation did not complete successfully, possibly due to:
  
  Syntax errors in the formula being evaluated.
  Invalid or missing input parameters.
  Runtime errors during formula evaluation (e.g., division by zero, invalid data types).
  Authorization or system issues preventing the function module from executing properly.
  Incompatibility or bugs in the underlying SAP kernel or component.
  
  
  Solution:
  To resolve the error, follow these steps:
  
  
  Check the Formula Syntax:
  
  Verify the formula passed to EVAL_FORMULA for correctness.
  Ensure that all variables and functions used in the formula are valid and properly defined.
  
  
  
  Validate Input Parameters:
  
  Check the input parameters passed to the function module.
  Make sure all required parameters are provided and have valid values.
  
  
  
  Debug the Function Module:
  
  If you have access, debug the call to EVAL_FORMULA to see what return code is being generated and why.
  Look for exceptions or error messages inside the function module.
  
  
  
  Check for System or Authorization Issues:
  
  Ensure the user executing the function has the necessary authorizations.
  Check system logs (SM21) and short dumps (ST22) for related errors.
