  The SAP error message RSDME811, which states "Connection parameter &1 not found," typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when there is an issue with the connection parameters defined for a data source or a data flow.
  Cause:
  
  Missing Connection Parameter: The error indicates that a required connection parameter (denoted by &1) is not defined in the system. This could be due to a misconfiguration or an oversight during the setup of the data source or connection.
  Incorrect Configuration: The connection parameters may have been incorrectly configured or deleted, leading to the system being unable to find the necessary information to establish a connection.

  Solution:
  
  Check Connection Parameters: Go to the relevant transaction (e.g., RSA1 for Data Warehousing Workbench) and check the connection parameters for the data source or InfoProvider that is causing the error. Ensure that all required parameters are defined correctly.

  Transport Check: If the issue arose after a transport, verify that all necessary objects and parameters were included in the transport request. You may need to manually add any missing parameters.
  Authorization Check: Ensure that the user has the necessary authorizations to access the connection parameters. You may need to consult with your SAP security team to verify this.
