• What is the cause and solution for SAP error message XE026 - Function module &1: default value '&2' used ?

  The SAP error message XE026 indicates that a function module is using a default value for a parameter instead of a value that was expected or provided. This typically occurs when a parameter is not explicitly passed to the function module, and the system resorts to using a predefined default value.
  Cause:
  
  Missing Parameter: The function module is called without providing all the required parameters, leading to the use of default values.
  Incorrect Function Call: The function module might be called incorrectly, or the parameters might not be aligned with the expected input.
  Parameter Configuration: The function module may have been designed to use default values for certain parameters, which can lead to unexpected behavior if the defaults are not suitable for the current context.
  
  Solution:
  
  Check Function Module Call: Review the code where the function module is called. Ensure that all required parameters are being passed correctly.
  Review Parameter Documentation: Look at the documentation for the function module to understand what parameters are required and what the default values are.
  Modify the Call: If necessary, modify the function call to include the appropriate values for the parameters instead of relying on defaults.
  Debugging: If the issue persists, consider debugging the function module to see what values are being passed and how the defaults are being applied.
  
  Related Information:
  
  Function Module Documentation: You can access the documentation for the specific function module in the SAP system (using transaction SE37) to understand its parameters and default values.
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific function module you are using.
  Testing: After making changes, test the function module to ensure that it behaves as expected with the new parameter values.
  
  By addressing the root cause of the missing or incorrect parameters, you can resolve the XE026 error and ensure that the function module operates correctly.
