• What is the cause and solution for SAP error message RSDME355 - Model has more than one Key, Update of results to BW not possible ?

  The SAP error message RSDME355 indicates that there is an issue with a data model in SAP BW (Business Warehouse) where the model has more than one key. This situation prevents the update of results to BW because the system cannot determine which key to use for the update.
  Cause:
  
  Multiple Keys Defined: The model in question has been defined with multiple keys, which can occur if the InfoObject or the data model is incorrectly configured.
  Inconsistent Data Model: The data model may not be aligned with the expectations of the BW system, leading to ambiguity in key identification.
  Data Source Configuration: The data source from which the data is being extracted may also be incorrectly set up, leading to multiple keys being recognized.
  
  Solution:
  
  
  Review the Data Model:
  
  Check the configuration of the InfoObjects and ensure that only one key is defined for the model.
  If multiple keys are necessary for your business logic, consider restructuring the model to accommodate this requirement.
  
  
  
  Adjust the Data Source:
  
  Verify the data source configuration to ensure it is correctly set up to provide a single key for the data being processed.
  If necessary, modify the extraction logic to ensure that it aligns with the BW model's expectations.
  
  
  
  Use a Composite Key:
  
  If your business requirements necessitate multiple keys, consider creating a composite key that combines the necessary fields into a single key.
  
  
  
  Check for Updates:
  
  Ensure that you are using the latest version of SAP BW, as updates may include fixes for known issues related to key handling.
