• What is the cause and solution for SAP error message /BOFU/FDT_EXP_BO_RET130 - Repeating key entry for node no. &1 will be deleted during save ?

  The SAP error message /BOFU/FDT_EXP_BO_RET130 indicates that there is a repeating key entry for a node in a data model or configuration that is being saved. This typically occurs in the context of SAP's Flexible Data Model (FDT) or Business Object Framework (BOF) when there are duplicate entries that violate the uniqueness constraints defined for that node.
  Cause:
  
  Duplicate Entries: The error is primarily caused by having multiple entries with the same key for a specific node in the data model. This can happen if the data is being imported or manipulated in a way that creates duplicates.
  Data Integrity Rules: The system enforces data integrity rules that prevent saving duplicate keys for nodes that require unique identifiers.
  Configuration Issues: There may be issues in the configuration of the data model or business object that lead to the generation of duplicate keys.
  
  Solution:
  
  Identify Duplicates: Review the entries for the node specified in the error message (indicated by &1). Check for any duplicate key entries that may exist.
  Remove Duplicates: If duplicates are found, you will need to remove or consolidate them to ensure that each key is unique before attempting to save again.
  Check Data Import/Export Logic: If the data is being imported from an external source, ensure that the import logic is correctly handling duplicates. You may need to adjust the data extraction or transformation process to prevent duplicates from being created.
  Review Configuration: Check the configuration of the data model or business object to ensure that it is set up correctly and that the uniqueness constraints are properly defined.
  Testing: After making the necessary changes, test the save operation again to confirm that the error has been resolved.
