• What is the cause and solution for SAP error message FDT_CORE390 - Invalid recursion: &1 holds a reference to itself ?

  The SAP error message FDT_CORE390: Invalid recursion: &1 holds a reference to itself typically occurs in the context of the SAP Form Data Tool (FDT) or when working with Adobe Forms in SAP. This error indicates that there is a recursive reference in the data structure or form definition, meaning that an object is referencing itself directly or indirectly, which is not allowed.
  Cause:
  
  Self-Referencing Structure: The most common cause of this error is that a field or node in the data structure is set to reference itself. This can happen if you have defined a field that points to itself in a way that creates a loop.
  Incorrect Data Binding: If you are binding data elements incorrectly in the form, it can lead to a situation where the form tries to access a field that references itself.
  Form Logic Issues: If there are scripts or logic in the form that inadvertently create a recursive call or reference, this can trigger the error.
  
  Solution:
  
  Check Data Structure: Review the data structure or the context in which the error occurs. Ensure that no field is referencing itself directly or indirectly.
  Review Form Bindings: Go through the bindings of the form fields and ensure that they are correctly set up. Make sure that no field is bound to itself.
  Debug Scripts: If there are any scripts or calculations in the form, check them for any logic that might cause a recursive reference. Modify the logic to prevent self-referencing.
  Test Changes: After making changes, test the form again to see if the error persists. If it does, continue to investigate other areas where recursion might be occurring.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error. Sometimes, specific versions of SAP software may have bugs that are documented in SAP Notes.
