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
