• What is the cause and solution for SAP error message SDX401 - Do not use a port with a dynamic file name ?

  The SAP error message SDX401: Do not use a port with a dynamic file name typically occurs in the context of SAP PI/PO (Process Integration/Process Orchestration) when dealing with file adapters. This error indicates that the configuration of the file adapter is not set up correctly, particularly regarding the naming of files.
  Cause:
  The error arises when a file adapter is configured to use a dynamic file name for the output file, which is not supported in certain scenarios. Dynamic file names can lead to issues with file handling, as the system may not be able to predict or manage the file names correctly.
  Solution:
  To resolve the SDX401 error, you should take the following steps:
  
  
  Check Adapter Configuration:
  
  Go to the configuration of the file adapter in your integration flow.
  Ensure that the file name is set to a static value rather than a dynamic one. This means you should specify a fixed name for the output file.
  
  
  
  Use Static File Names:
  
  If you need to include dynamic elements (like timestamps or unique identifiers), consider using a static base name and appending a static suffix or prefix instead of a fully dynamic name.
  
  
  
  Review Documentation:
  
  Consult the SAP documentation for the specific version of SAP PI/PO you are using. There may be additional guidelines or best practices for configuring file adapters.
  
  
  
  Testing:
  
  After making the changes, test the integration flow to ensure that the error is resolved and that files are being processed correctly.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes or updates that might address this issue or provide additional context.
