  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WS264 - Input data missing during call of function module &1
  
  Cause:
  This error occurs when a function module is called without providing the necessary input parameters. The function module expects certain mandatory input data, and if these are missing or not properly passed, the system raises this error.
  In other words, the program or user interface is trying to execute a function module, but the required input data for that function module is incomplete or absent.
  
  Typical Scenario:
  
  A custom or standard program calls a function module.
  The function module has mandatory importing parameters.
  The calling program does not supply these parameters or supplies them as initial/empty.
  The function module detects missing input and triggers the error WS264.
  
  
  Solution:
  
  
  Check the Function Module Call:
  
  Identify the function module name from the error message (parameter &1).
  Review the code where this function module is called.
  Verify that all mandatory importing parameters are correctly filled before the call.
  
  
  
  Provide Required Input Data:
  
  Ensure that the calling program or interface passes all required input parameters.
  If the input data comes from user input or another program, check that this data is correctly captured and passed.
  
  
  
  Debugging:
  
  Set a breakpoint at the function module call.
  Run the program and check the values of the importing parameters.
  Confirm that none of the mandatory parameters are initial or missing.
  
  
  
  Check Documentation:
  
  Use transaction SE37 to display the function module.
  Review the interface tab to see which parameters are mandatory.
  Check the documentation of the function module for any special requirements.
  
  
  
  Correct the Calling Program:
  
  Modify the program logic to ensure all required data is available before calling the function module.
  Add error handling to catch missing data before the call.
  
  
  
  
  Related Information:
  
  Transaction SE37: To check the function module interface and documentation.
  Debugging Tools: Use the ABAP debugger to analyze parameter values.
  SAP Notes: Sometimes, specific function modules may have known issues or patches.
  Custom Code: If this occurs in custom developments, review the code logic for data preparation.
  
  
  Summary:
  
  Error WS264 means mandatory input data is missing when calling a function module.
  Fix: Provide all required input parameters before the function module call.
  Check: Function module interface, calling program logic, and debug to identify missing data.
