How To Fix FDT_EXPRESSIONS847 - 2 or more parameters refer to the same object &1 with move type &2

SAP Error Message - Details

• Message type: E = Error

• Message class: FDT_EXPRESSIONS - Formula & Derivation Tool: Expressions

• Message number: 847

• Message text: 2 or more parameters refer to the same object &1 with move type &2

What causes this issue?

You have created an invalid mapping:
Two or more Exporting / Changing / Returning parameters of the procedure
to be called are mapped to the same BRFplus data object &v1& with move
type &v2&. Because of the two identical mappings to the same BRFplus
data object, one parameter would overwrite the other. As the system
cannot decide which parameter should be effective, this cannot be done
correctly.

System Response

The object cannot be activated.

How to fix this error?

Define new data objects for the mapping so that the system can properly
decide which parameter has to be mapped to which data object.

Procedure for System Administrators

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

• What is the cause and solution for SAP error message FDT_EXPRESSIONS847 - 2 or more parameters refer to the same object &1 with move type &2 ?

  The SAP error message FDT_EXPRESSIONS847 indicates that there is an issue with the way parameters are being referenced in a function or expression. Specifically, it means that two or more parameters are referring to the same object, which can lead to ambiguity or conflicts in processing.
  Cause:
  The error typically arises in scenarios where:
  
  You have defined multiple parameters in a function or expression that point to the same underlying object.
  The move type (e.g., input, output) of these parameters is conflicting, which can cause confusion in how the data should be handled.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Parameter Definitions: Check the parameters defined in the function or expression. Ensure that each parameter is uniquely defined and does not refer to the same object unless intended.
  
  
  Change Move Types: If the parameters are meant to refer to the same object, consider whether they should have different move types. Adjust the move types accordingly to avoid conflicts.
  
  
  Refactor Logic: If the logic requires that multiple parameters refer to the same object, consider refactoring the logic to avoid this situation. You might need to consolidate parameters or change how the data is processed.
  
  
  Consult Documentation: Review the SAP documentation or help resources related to the specific function or expression you are working with. There may be guidelines on how to properly define parameters.
  
  
  Testing: After making changes, test the function or expression to ensure that the error is resolved and that the desired behavior is achieved.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  Community Forums: Look for discussions in SAP community forums or platforms like SAP Community, where other users may have encountered and resolved similar issues.
  Debugging: If you have access to debugging tools, you can step through the code to identify where the parameters are being defined and how they are being used.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
