  The SAP error message 42355, which states "Select only one info object," typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when a user attempts to perform an operation that requires the selection of a single InfoObject, but multiple InfoObjects have been selected instead.
  Cause:
  
  Multiple Selections: The most common cause of this error is that the user has selected more than one InfoObject in a selection screen or in a query definition where only one is allowed.

  User Input Error: Users may not be aware that only one InfoObject should be selected, leading to confusion during data retrieval or reporting.
  
  Solution:
  
  Review Selections: Go back to the selection screen or query definition and ensure that only one InfoObject is selected. Deselect any additional InfoObjects that may have been inadvertently selected.
  Check Query Design: If you are designing a query, ensure that the structure allows for only one InfoObject to be selected. You may need to adjust the query settings or filters.
  User Training: Provide training or documentation to users to clarify the requirement of selecting only one InfoObject in specific scenarios.
  Debugging: If the error persists and you believe it should allow multiple selections, consider debugging the query or checking for any custom logic that may be enforcing this restriction.
