• What is the cause and solution for SAP error message SMT083 - Parameter "i_prefetch" must be of type "wuf_boolean" ?

  The SAP error message SMT083, which states that the parameter "i_prefetch" must be of type "wuf_boolean," typically indicates that there is a type mismatch in the parameters being passed to a function or method in your SAP application. This error is often encountered in the context of ABAP programming or when working with specific SAP modules that require certain data types.
  Cause:
  
  Type Mismatch: The parameter i_prefetch is expected to be of type wuf_boolean, which is a specific boolean type in SAP. If the value being passed to this parameter is of a different type (e.g., integer, string, etc.), the error will occur.
  Incorrect Data Assignment: If the variable assigned to i_prefetch is not properly defined or initialized, it may lead to this error.
  Function Module or Method Call: The error may arise when calling a function module or method that requires i_prefetch to be a boolean type, but the provided argument does not match this requirement.
  
  Solution:
  
  Check Data Type: Ensure that the variable or value being passed to i_prefetch is of the correct type. It should be a boolean value (true/false).
  
  In ABAP, you can define a boolean variable as follows:
  DATA: lv_prefetch TYPE wuf_boolean.
  lv_prefetch = abap_true.  " or abap_false
  
  
  
  Review Function Calls: If you are calling a function module or method, check the documentation or definition to confirm the expected data types for all parameters, especially i_prefetch.
  Debugging: Use debugging tools in SAP to trace the execution and see what value is being passed to i_prefetch. This can help identify where the type mismatch is occurring.
  Code Review: Review the code where i_prefetch is being set or passed to ensure that it is being assigned correctly.
  
  Related Information:
  
  Data Types in ABAP: Familiarize yourself with the different data types in ABAP, especially boolean types. The wuf_boolean type is often used in specific contexts, so understanding its definition and usage is crucial.
  SAP Documentation: Refer to the official SAP documentation for the specific function module or method you are working with to understand the expected parameter types.
  SAP Community: If you are unable to resolve the issue, consider reaching out to the SAP Community or forums where other developers may have encountered similar issues.
  
  By ensuring that the parameter i_prefetch is correctly defined and passed as a boolean type, you should be able to resolve the SMT083 error.
