How To Fix FL380 - Tables cannot contain any boxed components in RFC

SAP Error Message - Details

• Message type: E = Error

• Message class: FL - Function Builder messages

• Message number: 380

• Message text: Tables cannot contain any boxed components in RFC

What causes this issue?

Structures with boxed components are deep.
With the RFC, no deep structures can be used.

• What is the cause and solution for SAP error message FL380 - Tables cannot contain any boxed components in RFC ?

  The SAP error message FL380, which states "Tables cannot contain any boxed components in RFC," typically occurs when you are trying to pass a table that contains boxed components (like structures or complex types) in a Remote Function Call (RFC). In SAP, RFC is used to enable communication between different SAP systems or between SAP and non-SAP systems.
  Cause:
  The error arises because RFC does not support the transmission of tables that contain boxed components. Boxed components are complex data types that cannot be directly serialized for transmission over RFC. This limitation is due to the way data is structured and transmitted in RFC calls.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Modify the Data Structure: 
  
  Change the structure of the table you are trying to pass. Instead of using boxed components, use simple data types (like CHAR, NUMC, etc.) or flat structures that do not contain nested or complex types.
  
  
  
  Use Flat Structures: 
  
  If you need to pass complex data, consider flattening the structure. This means breaking down the complex types into simpler, individual fields that can be easily transmitted.
  
  
  
  Create Separate RFC Function Modules: 
  
  If the boxed components are necessary for your logic, consider creating separate RFC function modules that handle the boxed components individually and return the results in a simpler format.
  
  
  
  Check Data Types: 
  
  Review the data types used in your RFC function module. Ensure that all parameters, especially those that are tables, are defined using compatible data types.
  
  
  
  Testing: 
  
  After making the necessary changes, test the RFC call again to ensure that the error is resolved.
  
  
  
  Related Information:
  
  RFC Function Module: An RFC function module is a special type of function module that can be called from other SAP systems or external applications.
  Boxed Components: In the context of SAP, boxed components refer to complex data types that encapsulate multiple fields or structures. These are not directly supported in RFC calls.
  SAP Documentation: For more detailed information, refer to the official SAP documentation regarding RFC and data types. This can provide insights into best practices for designing RFC-enabled function modules.
  
  By following these steps, you should be able to resolve the FL380 error and successfully pass the required data through your RFC calls.
