• What is the cause and solution for SAP error message EU485 - Dialog transaction: Start dynpro &1 cannot be a selection dynpro ?

  The SAP error message EU485 indicates that there is an issue with the dialog transaction you are trying to execute. Specifically, the message states: "Start dynpro &1 cannot be a selection dynpro." This means that the program is attempting to start a dialog transaction with a selection screen (a screen that allows users to input parameters for report execution), which is not allowed.
  Cause:
  The primary cause of this error is that the transaction you are trying to execute is defined to start with a selection screen (dynpro) instead of a standard dialog screen. In SAP, dialog transactions must start with a screen that is not a selection screen. This is a restriction in the way SAP handles dialog transactions.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Transaction Definition: Verify the transaction definition in the SAP system. Ensure that the transaction is set up correctly and that it points to a valid dialog screen (not a selection screen).
  
  
  Modify the Program: If you have access to the ABAP code, you may need to modify the program to ensure that it starts with a proper dialog screen. This may involve changing the screen number in the transaction definition or modifying the program logic.
  
  
  Use a Different Transaction: If the transaction you are trying to execute is not meant to be a dialog transaction, consider using a different transaction that is designed for selection screens.
  
  
  Consult Documentation: Check the SAP documentation or help resources for the specific transaction you are trying to use. There may be specific instructions or notes regarding its usage.
  
  
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP support team for further assistance.
  
  
  Related Information:
  
  Transaction Codes: You can check the transaction codes associated with the program in transaction SE93 (Transaction Codes) to see how they are defined.
  Screen Flow Logic: Review the screen flow logic in the program using transaction SE80 (Object Navigator) or SE38 (ABAP Editor) to understand how the screens are structured.
  SAP Notes: Search for relevant SAP Notes that may address this specific error or provide additional context.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
