  The SAP error message WUF081 indicates that the parameter i_prefetch must be defined as an "Importing" parameter in the context of a function module or method. This error typically arises when there is a mismatch in the definition of parameters in the function module or method signature.
  Cause:
  The error occurs when:
  
  The parameter i_prefetch is not defined correctly in the function module or method interface.
  It is likely defined as a different type (e.g., "Changing" or "Exporting") instead of "Importing".
  
  Solution:
  To resolve this error, you need to check and modify the definition of the parameter i_prefetch in the function module or method where the error is occurring. Here are the steps to do this:
  
  
  Access the Function Module/Method:
  
  Go to transaction SE37 (for function modules) or SE80 (for classes and methods).
  Enter the name of the function module or class/method where the error is occurring.
  
  
  
  Check Parameter Definition:
  
  In the function module or method interface, look for the parameter i_prefetch.
  Ensure that it is defined as an "Importing" parameter.
  
  
  
  Modify Parameter Type:
  
  If i_prefetch is not defined as "Importing", change its type to "Importing".
  Save and activate the changes.
  
  
  
  Test the Functionality:
  
  After making the changes, test the function module or method to ensure that the error no longer occurs.
