• What is the cause and solution for SAP error message FPAPICHK011 - Node name & is not unique ?

  The SAP error message FPAPICHK011 indicates that there is a problem with the uniqueness of node names in the context of the SAP system, particularly in relation to the Application Interface Framework (AIF) or similar configurations where nodes are defined.
  Cause:
  The error occurs when the system detects that there are multiple nodes with the same name in the configuration. This can happen due to:
  
  Duplicate Node Definitions: Two or more nodes have been defined with the same name in the configuration settings.

  Review the configuration settings to ensure that they are set up correctly and that no unintended duplicates exist.
  
  
  
  Transport Requests:
