How To Fix FDT_EXPRESSIONS845 - 2 or more parameters are mapped on data object &1 with move corresponding

FDT_EXPRESSIONS845 - Overview

• Message type: E = Error

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

• Message number: 845

• Message text: 2 or more parameters are mapped on data object &1 with move corresponding

What causes this issue?

The system has determined an invalid mapping: Two or more Exporting /
Changing / Returning parameters are mapped to the same BRFplus structure
&v1& with subsequent MOVE statements of type MOVE-CORRESPONDING.
During the part of the processing when the parameters are mapped back to
the BRFplus data objects, those parameters will be mapped using the
MOVE-CORRESPONDING statement. With MOVE-CORRESPONDING, the system
alwaysinitializes the data object, so a second MOVE-CORRESPONDING would
erase the data written by the first MOVE-CORRESPONDING.

System Response

The object cannot be activated.

How to fix this error?

Resolve the subsequent MOVE-CORRESPONDING statements into distinct MOVE
statements for each of the remaining fields.

Procedure for System Administrators

• What is the cause and solution for SAP error message FDT_EXPRESSIONS845 - 2 or more parameters are mapped on data object &1 with move corresponding ?

  The SAP error message FDT_EXPRESSIONS845 indicates that there is an issue with the mapping of parameters in a data object within the context of a data flow or expression. Specifically, it suggests that two or more parameters are being mapped to the same data object using the "move corresponding" statement, which is not allowed.
  
  Cause:
  The error occurs when:
  
  You have defined multiple parameters in a function module or method that are trying to map to the same data object.
  The "move corresponding" statement is used to transfer data from one structure to another, but it cannot handle multiple mappings to the same target field.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Parameter Mapping: Check the parameters that are being passed to the function or method. Ensure that each parameter is mapped to a unique data object.
  
  
  Modify the Data Flow: If you need to map multiple parameters to a single data object,
