• Message number: 394

• Message text: Only standard, sorted and hashed tables are allowed for RFC

What causes this issue?

Complex data types are allowed with RFC as IMPORTING and EXPORTING
parameters, but only those table types whose access mode is defined as
'Standard', 'Sorted' or 'Hashed' are supported. You chose a different
access type.

• What is the cause and solution for SAP error message FL394 - Only standard, sorted and hashed tables are allowed for RFC ?

  The SAP error message FL394 indicates that there is an issue with the type of table being used in a Remote Function Call (RFC). Specifically, the error states that only standard, sorted, and hashed tables are allowed for RFC. This means that the table you are trying to use in your RFC-enabled function module is not of an acceptable type.
  Cause:
  The error occurs when:
  
  You are trying to use a table type that is not supported for RFC. This includes:
  
  Database tables
  Pool tables
  Cluster tables
  Any other non-standard table types
  
  
  The function module is defined to use a table parameter that does not conform to the RFC requirements.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Table Type: Ensure that the table you are using in your RFC-enabled function module is either a standard table, sorted table, or hashed table. You can check the table type in the ABAP Dictionary (transaction SE11).
  
  
  Modify the Function Module:
  
  If you are using a non-standard table, you will need to change the table type to one of the allowed types.
  If you are using a structure or a complex data type, consider converting it to a standard table type.
  
  
  
  Redefine the Table Parameter: If the table parameter in your function module is defined incorrectly, redefine it to use a standard, sorted, or hashed table.
  
  
  Testing: After making the necessary changes, test the RFC call again to ensure that the error is resolved.

  Table Types:
  
  Standard Table: A table that allows duplicate entries and is not sorted.
  Sorted Table: A table that is sorted and allows duplicate entries.
  Hashed Table: A table that is optimized for fast access and does not allow duplicate entries.

  By ensuring that you are using the correct table types in your RFC-enabled function modules, you can avoid the FL394 error and ensure smooth communication between systems.
