• What is the cause and solution for SAP error message FDT_EXPRESSIONS712 - Invalid data object assignment; source is equal to target (position &1) ?

  The SAP error message FDT_EXPRESSIONS712 indicates that there is an invalid data object assignment in your expression. Specifically, the error states that the source and target of the assignment are the same, which is not allowed. This typically occurs in the context of using the SAP Fiori Design Time (FDT) or in the context of ABAP programming where expressions are evaluated.
  Cause:
  The error arises when you attempt to assign a value from one variable (source) to another variable (target) where both variables refer to the same data object. This can happen in various scenarios, such as:
  
  You are trying to assign a value to a variable that is already being used as the source of that value.
  There is a logical error in your expression where the source and target are inadvertently set to the same variable.
  
  Solution:
  To resolve this error, you should:
  
  
  Check the Assignment: Review the expression or code where the assignment is taking place. Ensure that the source and target variables are different and that you are not trying to assign a value to a variable that is also being used to provide that value.
  
  
  Modify the Expression: If you find that the source and target are indeed the same, modify your expression to use different variables. For example, if you have:
  target_variable = source_variable.
  Ensure that target_variable and source_variable are not the same.
  
  
  Debugging: If you are unsure where the error is occurring, use debugging tools to step through your code and identify the exact line that triggers the error.
  
  
  Consult Documentation: If you are using specific FDT features or expressions, refer to the SAP documentation for guidance on proper usage and examples.
