What causes this issue?

You have assigned a parameter to the method parameter from a function
module to which a field or a structure from the ABAP/4 Dictionary is
assigned as a data type reference. However, the method parameter has a
different dictionary reference.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

You should assign the same data type reference to the method parameter
as in the function module or implement a process to convert the method
parameter into the same type as the function module parameter in the
method before the function module is called.

  The SAP error message OL381 typically indicates that there is an issue with a function module parameter that refers to a structure or field that is not defined or is not accessible in the current context. This error can occur in various scenarios, such as when calling a function module or when working with data structures in ABAP programs.
  Cause:
  
  Undefined Structure/Field: The structure or field referenced in the function module parameter does not exist in the current program or context.
  Incorrect Data Type: The data type of the parameter being passed does not match the expected data type defined in the function module.
  Authorization Issues: The user may not have the necessary authorizations to access the structure or field.
  Transport Issues: If the function module or its associated structures were recently transported, there may be inconsistencies in the system.
  
  Solution:
  
  Check Structure/Field Definition: Verify that the structure or field referenced in the error message is correctly defined in the Data Dictionary (SE11). Ensure that it exists and is active.
  Review Function Module Parameters: Go to transaction SE37 (Function Builder) and check the parameters of the function module. Ensure that the parameters are correctly defined and that you are passing the correct data types.
  Data Type Compatibility: Ensure that the data type of the variable you are passing matches the expected data type of the function module parameter.
  Authorization Check: Ensure that the user has the necessary authorizations to access the structure or field.
  Transport Consistency: If the issue arose after a transport, check if all related objects were transported correctly. You may need to re-transport or adjust the objects.
  Debugging: If the issue persists, consider debugging the program to trace where the error occurs and to inspect the values being passed to the function module.
