• What is the cause and solution for SAP error message RSWADMDERR1211 - Choice parameter &2 with value &1 of object &3 has more than one LL node ?

  The SAP error message RSWADMDERR1211 indicates that there is an issue with a choice parameter in a data model or a similar configuration where the specified choice parameter has more than one LL (Logical Layer) node associated with it. This can occur in various contexts, such as when working with SAP BW (Business Warehouse) or SAP HANA models.
  Cause:
  The error typically arises when:
  
  Multiple LL Nodes: The choice parameter is defined in such a way that it points to multiple logical layer nodes, which is not allowed. Each choice parameter should ideally map to a single logical layer node.
  Configuration Issues: There may be a misconfiguration in the data model or the way the parameters are set up, leading to ambiguity in the choice parameter's definition.
  Data Model Complexity: In complex data models, especially those involving multiple hierarchies or relationships, it can be easy to inadvertently create overlapping definitions.
  
  Solution:
  To resolve the RSWADMDERR1211 error, you can take the following steps:
  
  
  Review the Choice Parameter: Check the definition of the choice parameter in the data model. Ensure that it is correctly defined and that it points to a single logical layer node.
  
  
  Check LL Node Assignments: Verify the assignments of LL nodes to the choice parameter. If there are multiple nodes assigned, you will need to decide which one is appropriate and remove the others.
  
  
  Simplify the Model: If the data model is overly complex, consider simplifying it. This may involve breaking down the model into smaller, more manageable components or re-evaluating the relationships between nodes.
  
  
  Consult Documentation: Refer to SAP documentation or help resources specific to the version of SAP you are using. There may be specific guidelines or best practices for defining choice parameters and logical layer nodes.
  
  
  Testing: After making changes, test the data model to ensure that the error is resolved and that the model behaves as expected.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with a technical expert who has experience with the specific SAP module you are working with.
